PREFACE 

The following report is the sixth in a series of such documents that present 

the findings of field tests conducted under the Department of Energy's (DOE) 

Cooperative Field Test Program with the u.s. wind industry. This report 

provides the results of a study to collect data at two windfarms. The two 

wind turbine arrays, located in the Altamont Pass east of San Francisco, were 

instrumented with anemometers and a central monitoring computer. To obtain a 

high spatial density of wind-speed measurements, every other turbine in both 

arrays was instrumented. Wind-speed data were collected over a period of four 

days during the summer high-wind season wi th all turbines shut down. The 

resultant data set was analyzed to determine the spatial variability of the 

wind resource in the two arrays. Because no turbine wakes were present, 

variation in the flow was caused by the interaction of the flow with the 

terrain and was not a function of turbine wake interaction. 

The free-flow data sets can be used by other researchers to refine numerical 

free-flow computer models. The data sets will be used to fine tune and validate these computer models. In addition, the free-flow data will be compared 

to results of a wake energy deficit study also under way on these turbine 

arrays. 

The success of this project is due to a number of people, who the author

Corporation (now KENETECH Service Company) managed the entire project. Richard 

Farrell and Kevin O'Keefe of Altamont Energy Corporation assisted in arranging 

private-sector funding. Dave Kresse, of KENETECH Service Company, helped 

supervise the installation and operation of the data collection network.

SUMMARY 

The objective of the free-flow study was to collect a sufficient wind data 

base to describe the general spring/summer (high-wind season) wind flow over 

the Jess and Souza Ranch areas. To do this, a central monitoring computer was 

installed on each ranch. The computers were connected by communication cables 

to 50 turbines on the Souza Ranch and 150 turbines on the Jess Ranch. Anemometers were installed on every other turbine on 12-ft booms 35 ft above ground 

level (AGL). Spacing between anemometers was approximately 200 ft in the 

crosswind direction by 450 ft in the parallel direction. A total of 23 turbines on the Souza Ranch were instrumented this way, as were two multilevel 

meteorological towers. On the Jess Ranch, 77 turbines were instrumented, 

about half at 35 ft AGL and half at 50 ft AGL, and four additional towers were 

also instrumented. 

Wind data were collected for approximately a 100-hour period on each ranch. 

All turbines were shut down during these periods so that no turbine wakes 

would be present. The data periods were selected by the meteorologist to 

insure that they occurred during typical spring/summer flow regimes. 

There were several reasons for collecting this free-flow data: 

• The data were to be analyzed to determine the flow variability over the 

study area. The high density of sensors, which was nearly unprecedented in 

previous publicly funded micrositing studies, allowed a microscale examination of the spatial flow variability. Large variations in energy production 

had been observed previously within these turbine arrays and at other similar arrays. The free-flow data set allowed a determination of how much of 

this variability was caused by differences in ambient flow conditions, 

without turbine wakes. 

• The two ranches had different levels of terrain complexity; this would 

allow a comparison of terrain influences on the two ranches. 

• The variations in available energy would be compared to subsequent wake 

energy-deficit measurements to be made on the same ranches. 

• The data set would be useful to other researchers, especially those interested in computer modeling of flow over complex terrain. 

The raw data collected by the central computer consisted of 10-minute averages. These lO-minute averages were processed into hourly averages. The 

hourly averages were screened to ensure the quality of the data. When that 

process was completed, the data from all turbine anemometers were correlated 

to a designated upwind reference anemometer. Correlation coefficients and 

speed ratios were calculated between the turbines and the reference site. The 

ratios were then plotted on topographic maps, and isopleths were drawn around 

areas of equal speed ratios. By observation, patterns in the flow were quite 

apparent. 

On the Souza Ranch, speed ratios to the reference tower ranged from 77% to 

110%, for a range of 33%. On the Jess Ranch, ratios ranged from 60% to 100%, 

for a range of 40%. On both ranches, flow variations over very small areas 

were present. For example, within a distance of 400 ft, changes of 20% in 

speed and 35% in theoretical energy were measured.

STR-3404 

Elevation enhances flow, as expected. However, upstream terrain features 

appear to play the most significant role in flow variability in these study 

areas. Several valleys oriented parallel to the predominant flow appear to 

channel the flow to a great extent. Turbine anemometers downwind of the 

valleys had enhanced wind speeds relative to other turbines away from the 

outflow from these valleys. Small hills approximately 150 ft higher than the 

surrounding terrain had the opposite effects of the valleys. Turbines located 

up to 1500 ft downwind of these hills had lower speed ratios than did surrounding turbines. Correlation coefficients at these sites were also affected 

by these hills. The coefficients were generally lowest at these sites. 

However, the correlation coefficients improved dramatically as the height of 

the low-level subsidence inversion increased. The speed ratios at these sites 

also improved as the inversion height increased. Terrain features upwind of 

the site appear to playas significant a role in the flow variability as do 

terrain features within the site.

1.0 INTRODUCTION 

Approximately 7000 wind turbines, ranging in size from 20 kW to 750 kW, have 

been installed in the Altamont Pass during the 1980s. Few wind developers had 

the opportunity to conduct detailed micrositing studies. Many felt it was 

adequate to make wind measurements at one to five sites per square mile. 

Thus, wind turbine developers and operators have been amazed at the enormous 

variability in energy production within the pass, both between turbine arrays 

and, especially, within the arrays. The enormous variations could be caused 

by (1) individual turbine operating characteristics, (2) free-flow variability 

from terrain, or (3) wake effects. This free-flow study was conducted to 

explain turbine production variabili ty and, in particular, to addres s the 

free-flow variability. A second study was also conducted simultaneously to 

address the wake effects. 

1.1 Meteorological Discussion of the Altamont Pass 

A brief discussion about the driving mechanism of the winds in the Altamont 

Pass is appropriate. The Altamont Pass is located in a gap in the California 

coastal range, approximately 45 miles east of San Francisco. To the east of 

the pass lies the great Central Valley, and to the west lies several ranges of 

coastal hills, the San Francisco Bay, and the Pacific Ocean. During the 

spring and summer months, the high-wind season, there is a large temperature 

gradient between the cool Pacific Ocean and the hot interior valleys. The 

coastal waters near San Francisco remain in the high 50s (15°C), whereas the 

Central Va11ey temperatures rise to nearly 100° (35 °C). As the interior 

temperatures rise, air density decreases and the hot, low-density air rises. 

This creates a low-pressure area over the interior, known as a thermal trough. 

The thermal trough can usually be found in the summer months, extending from 

the Coachella Valley in southeastern California up through the Central Valley 

(Sacramento - San Joaquin). Over the eastern Pacific Ocean, which is cool by 

comparison, the Pacific high-pressure cell is nearly always present. Thus, 

there is a pressure difference or gradient between the coast and the inland 

valleys. The result of this pressure difference is wind that blows from areas 

of high pressure to low pressure. 

A second important meteorological feature is the subsidence inversion. An 

inversion occurs when a layer of warm air is found over a layer of cool a1r. 

Associated with the Pacific high-pressure cell is the west-coast subsidence 

inversion, the culprit blamed for trapping California smog. This inversion is 

present along the California coast and over the eastern Pacific during most of 

the spring and summer months. The mean summer height of the inversion base, 

measured at the Oakland airport (about 35 miles west of the pass) is 1350 ft 

above mean sea level (MSL). Measurements of the inversion height in the pass 

itself show it to be several hundred feet AGL, which is slightly lower than it 

is in Oakland. 

The significance of the inversion 1S that it acts as a lid. Air flowing 

inland from high pressure to low pressure is accelerated through coastal gaps 

like the Altamont Pass. The presence of the inversion enhances the venturi 

effect of the pass by providing an additional constriction to the flow, from 

the top. Thus, air flow is squeezed from the bottom and sides by the pass 

itself, and from the top by the inversion. In addition, the inversion can 

enhance the blocking capability of obstacles such as hills. If the inversion 

1 
is strong and fairly close to the ground, the wind ~s 

hills rather than over them.

forced to flow around 

The inland pressure gradient and the inversion are the basic elements responsible for the persistent spring/summer winds in the Altamont Pass. As 

mentioned earlier, the height of the inversion in the pass is only several 

hundred feet AGL. Wind speeds are higher below the invers ion, and decrease 

with height above the inversion. At times, the inversion is very close to the 

ground and vertical wind shear is negative (i.e., wind speeds decrease with 

height). 

The free-flow data were collected during typical spring/summer conditions. A 

detailed synoptic discussion of the meteorological conditions during the 

free-flow periods can be found in Appendix A.

STR-3404 

2.0 STUDY METHODOLOGY 

The methodology for the free-flow study was to collect several days of 

10-minute-average wind data from the anemometer arrays. The data were collected during typical spring/summer (high-wind) season flow regimes. All 

turbines were shut down during the data collection periods. 

The 10-minute data were processed to hourly averages and analyzed on a mainframe computer. The analysis consisted of calculating correlation coefficients and speed ratios between a designated reference site and all other 

sites. The values were then manually plotted, and isopleths were drawn. 

2.1 Study Areas 

The Jess Ranch study area is In the eastern portion of the Altamont Pass. The 

ranch is on relatively flat terrain, by Altamont Pass standards, with elevation dropping gently to, the northeast. Although the study area is relatively 

flat, the terrain immediately upwind is qui te complex. There are two hills 

just west of the Jess Ranch that are several hundred feet higher than the 

ranch. Elevations in the study area range from 600 ft MSL in the southwest 

corner to 400 ft MSL in the northeast corner. The study area is approximately 

one-half square mile, one mile long (in the north-south direction) and onehalf mile wide. The northern half of the ranch has Nordtank turbines, and the 

southern half has ESI turbines. Figure 2-1 is a topographic map of the Jess 

Ranch and surrounding terrain. 

The Souza Ranch study area is in the northern portion of the Altamont Pass, 

about six miles north-northwest of the Jess Ranch. The terrain in the Souza 

study area is more complex than that in the Jess study area. The study area 

is on gently rolling hills. Immediately south of the study area is a canyon 

trending east-west, with an elevation of about 350 ft MSL. Elevations in the 

study area range from 440 ft MSL in the western portion to 300 ft MSL in the 

eastern portion. The Souza study area is about half the size of the Jess 

area. All turbines In the Souza Ranch study area are Nordtanks. Figure 2-2 

IS a topographic map of the Souza area and surrounding terrain. 

2.2 Monitoring Equipment 

2.2.1 Anemometry 

Due to the relatively flat terrain on the Jess Ranch, the turbines are laid 

out in straight rows, normal to the west-southwest flow. Spacing between 

turbines, within rows, is 100 ft (2 rotor diameters); spacing between rows is 

about 450 ft (9 rotor diameters). Anemometers were installed on every other 

turbine, so the spacing between sensors is 200 ft crosswind by 450 ft downwind. Figure 2-3 is a topographic map of the Jess Ranch and shows the locations of the turbines and anemometer towers. The large letters indicate the 

locations of groups of turbines. Individual turbines are plotted as small 

triangles, and only the end turbines in a given row are labeled. For example, 

see the upper left corner of Figure 2-3, in the row adjacent to the J-08 

anemometer. Here, there are six turbines, but only Ll and L6 are labeled. 

A total of 77 anemometers were installed on the Jess Ranch on booms on every 

other turbine. Again, the southern half of the Jess Ranch consists of ESI-54S

turbines on 80-ft towers. On Figure 2-3, these are in the C, D, E, H, I, and 

J groups. The northern half of the ranch consists of Nordtank 65-kW turbines 

on 72-ft towers. These are in groups F, G, K, L, M, and N. Anemometers were 

installed on the ESI-54S turbines on existing 5-ft booms at 50 ft AGL. Anemometers were installed on the Nordtank turbines on 12-ft booms at 35 ft 

AGL. A longer boom was used on the Nordtanks because of their large tubular 

tower (versus the open-lattice ESI tower). The anemometers were installed at 

the 35-ft (versus 50-ft) level to keep them below the rotor. The boom orientation was north-northwest, which is normal to the flow, so there was no tower 

shadow. On the Nordtank turbines, 35 ft AGL is about 11 ft below the bottom 

of the rotor; on the ESI turbines, 50 ft AGL is 3 ft below the rotor. Of 

course, the rotors were stationary during the free-flow data collection 

period, so no interference was expected. 

In addition to the 77 anemometers installed on turbines, there were five 

additional meteorological towers. Table 2-1 lists the towers, their locations, measurement levels, and sensor types. Note that two of the Jess Ranch 

towers were not integrated with the central monitoring computer (to be discussed hereafter), and data collected at these towers were hourly averages, 

not 10-minute averages.

The Souza Ranch terrain is slightly more complex than that of the Jess study 

area, and the turbine rows follow the local ridge lines to some extent. The

STR-3404 

turbine rows are not as straight, nor are they all parallel. Spacing between 

anemometers and sensor height is the same as on the Jess Ranch. However, the 

boom orientation is northwesterly because the prevailing wind direction is 

southwesterly. Figure 2-4 is a topographic map showing the location of turbine anemometers and towers. Anemometers were installed on 23 Souza turbines 

as well as 3 meteorological towers. Table 2-2 lists the characteristics of 

these towers. All three towers were connected to the central monitoring 

computer.

Except for those on the two reference towers, all sensors were Maximum type 

40 cups. The sensors are molded-lexan 3-cup anemometers. The transducer is 

an alternating current (AC) generator that produces a sine wave signal. The 

signal frequency is proportional to wind speed. The manufacturer specifies 

the accuracy to be +2.5% of actual speed and the distance constant to be 

9.7 ft. 

The two reference towers, J-08 on Jess and 8-13 on 8ouza, had R.M. Young "Wind 

Monitor" Model 1105103 propvanes. Wind direction is measured with a potentiometer, and wind speed is measured with an AC sine wave generator. The manufacturer specifies the distance constant to be 8.9 ft and the accuracy to be 

+2.0% of actual speed. 

Approximately 60 of the Maximum cups and both propvanes were tested in the 

University of California at Davis wind tunnel. The test procedure called for 

approximately 30 samples for each sensor in wind speeds ranging from 10 to 

60 mph. Almost all of the cups tested read 1%-2% below tunnel speed, and the 

mean speed of al1 cups tested was 98.7% of tunnel speed. The two propvanes 

read about 1% above tunnel speed. Appendix B lists the results of the wind 

tunnel tests and the location of sensors. 

2.2.2 Central Monitoring Computer and Communicating Turbine Monitors (CTKs) 

The Second Wind, Inc., moni toring system on each ranch has two main components: (1) the central computer and (2) the CTMs. Each individual turbine has 

a CTM that monitors turbine status, turbine power, and wind speed and direction (if wind sensors are installed). The CTMs operate on a one-second scan 

interval and calculate and store 10-minute averages. The eTMs are connected 

8 
STR-3404 

9 
STR-3404 

vla cable to the central computer, which interrogates all turbines once a 

minute. The central computer performs many functions; of particular importance to this study is the data archiving function. The lO-minute data are 

stored on a Bernoulli disk drive, which permits these data to be accessed by 

other computers. 

Because of the electrical nOlse in a wind-farm environment, the CTM has a 

threshold voltage for wind-speed signals. This threshold is equivalent to 

roughly 2 mph for a Maximum cup and slightly higher for an R.M. Young propvane. A one-second scan below this 2-mph threshold would be interpreted as a 

O-mph reading. Thus, a lO-minute average of 0 mph could actually have been 

between 0 and 2 mph. Furthermore, during any 10-minute period below about 

5 mph, there could be excursions below 2 mph that would be read as zero. Thus, 

a true average wind speed of 5 mph could be archived as a 4.5-mph average. As 

the average wind speed increases, there are fewer excursions below 2 mph, and 

this bias goes to zero. Almost all of the data collected were in winds well 

above 10 mph, so this problem is trivial. However, there are a few averages 

in the data set in the range of 0-5 mph that are negatively biased. 

2.3 Data Processing 

The Second Wind, Inc., field computer stores the 10-minute averages. These 

data are transferred to the office computer on a Bernoulli disk. The office 

computer has two programs that were used to access these data. One program is 

a Data Dump facility that allows the user to specify a start and end time and 

a range of parameters. It creates a file that can be printed out for review 

of the 10-minute records. A second program is the hourly program that computes hourly averages from the six 10-minute records. The program creates an 

hourly average for any hour when three or more valid 10-minute records were 

available. The hourly program was used on all sites to generate hourly data. 

The hourly averages were transferred from the office computer to a PRIME 

mainframe computer for quality assurance (QA) and subsequent analysis. 

2.3.1 QA Procedures 

The hourly averages were loaded into a PRIME computer, where an extensive wind 

energy data base and software library resides. The QA procedures required 

calculating correlation coefficients and speed ratios, and also reviewing and 

plotting these. This was followed by scrutinizing any outlying data points 

that were revealed by these plots, and making some subjective judgment as to 

the data points' validity. Specifically, the following steps were taken: 

1. Calculate correlation coefficients and speed ratios between the reference 

anemometer and all other sites on the ranch 

2. Calculate correlation coefficients and speed ratios between all adjacent 

pairs of anemometers 

3. Review the correlation coefficients and speed ratios, and investigate any 

sites that had peculiar speed ratios or correlations below 0.9 

4. Scan both the hourly and 10-minute data listings to spot any suspect data 

points (an example of a suspect data point might be a O-mph wind speed at 

one level of a tower and a 20-mph wind speed at another level) 

5. Delete any invalid data 

10 
STR-3404 

6. Recalculate correlation coefficients without invalid data and verify that 

a significant improvement in correlation was achieved 

7. Fill in gaps where data were deleted using surrogate data from closest 

adjacent site (surrogate data points were created using linear regression 

equations). 

Review of the Souza data set revealed no spurious data. All correlations were 

between 0.94 and 1.00. A total of 2726 parameter-hours of data were collected, 

with a data recovery of 100%. 

Review of the Jess data set revealed suspect data at six sites. In most cases, 

the suspect data were for O.O-mph wind speeds when other levels or adjacent 

sites had strong winds. It has not been determined if the cause was a sensor, 

sensor wire, CTM, or communication failure. Table 2-3 lists suspect data 

sites.

Thus, two sites, F5 and 112, were deleted altogether; an additional 55 hours 

of data from four turbines were also deleted. A total of 8717 parameter-hours 

of valid data were collected out of a possible 8976 parameter-hours, for a net 

data recovery of 97.1%. The 55 hours of data were filled in at the four sites 

listed above; however, no attempt was made to fill in data from turbines F5 

and 112. Data recovery for the entire study, including both areas, was 97.8%. 

This is an excellent rate of data recovery for a study of this scale. 

2.3.2 Site J-08 Sensor Problems 

Two problems were detected with the R.M. Young sensor at site J-08. This sensor was installed on September 7, 1987. Prior to this installation, three 

years of data had been collected at this site, as well as at site J-04. The 

established speed ratio between these sites for the previous three Septembers 

was 98.8% (J-08 was 98.8% of J-04). After installation of the R.M. Young sensor, this ratio jumped 2.8%, to 101.6% of J-04. It was felt that the J-08 

sensor might have a positive bias. To determine if this were true (in the 

field), a calibrated Maximum cup was installed at J-08 at the same level, in 

the field in January 1988. Three months of concurrent wind-speed data were 

collected by these two sensors. Correlation of all concurrent wind data, in 

11 
STR-3404 

winds of 10 mph or greater, showed that the R.M. Young sensor was reading 2% 

higher than was the Maximum cup. The correlation was perfect. As a result, 

all wind speeds at J-08 were reduced by 2% to reflect this field calibration. 

The other problem with site J-08 was in orientation of the vane. It was discovered that the north point on the wind 'vane was oriented toward 22.5 0, or 

22.5° east of true north. With this orientation, all wind-direction data 

would be recorded 22.5° too low. (For example, a true north wind at 360 0 

would read 337.5°.) It was evident from the base plate and guy wires that the 

mast had not turned but had been installed incorrectly. Therefore, 22.5° have 

been added to J-08 wind-direction data. 

These problems were not evident at the other R.M. Young sensor installed at 

site S-13 on the Souza Ranch.

3.0 DATA ANALYSIS 

3.1 Data Sets 

Data collection took place on the Souza Ranch from September 10, 1987 at 1600 

Pacific Daylight Time (PDT) through September 14, 1987 at 1400 PDT. The duration of the data collection phase was 94 hours, representing 564 10-minute 

samples. Data collection on the Jess Ranch took place in two periods: from 

October 1, 1987 at 1400 PDT through October 3, 1987 at 0500 PDT; and from 

October 7, 1987 at 0800 PDT through October 10, 1987 at 0900 PDT. During 

the first period on the Jess Ranch, light and variable winds occurred on 

October 2; these data were not included in the final data set. The duration 

of the Jess data collection phase was 102 hours, representing 612 10-minute 

samples. Although data collection took place in October on the Jess Ranch, 

the meteorological conditions were typical of summer, as shown in Appendix A. 

Appendix A is a detailed synoptic discussion of the atmospheric conditions 

that occurred during the free-flow periods. A descriptive paragraph and two 

weather maps are included for every 12-hour period. The weather maps are a 

western U.S./eastern Pacific surface map and an "upper air" map of the 500-mb 

(18,000-ft) level. This appendix will be of particular interest to meteorologists or readers with some knowledge of the subject. 

A complete listing of the hourly data can be found in Appendix C, which lists 

up to 48 hours of data for 15 sites on each page. Data are listed synoptically (i.e., each line of data lists data for one hour for 15 sites). 

3.2 Linear Correlations 

Correlation is defined as the degree of relationship between variables. The 

correlation coefficient is a dimensionless number that varies from -1 to +1. 

A positive correlation means that variable y tends to increase as variable x 

increases. A negative or inverse correlation means that variable y tends to 

decrease as variable x increases. The correlation coefficient should not be 

confused with a ratio; two variables or sites could have a high degree of 

correlation, close to 1.0, but have a ratio very different from unity. The 

square of the correlation coefficient is called the coefficient of determination. It is a useful term that is equal to the ratio of explained variation 

between two variables to the total variation. 

Artificially high linear correlations can exist between two variables if both 

variables depend on time. Because many meteorological parameters are timedependent, the reader is cautioned that to some degree the high correlations 

discussed hereafter could be due to this phenomenon.

Table 3-2 lists the correlation coefficients for the Jess Ranch. The correlations include the surrogate data points at the four sites listed in Table 2-3. 

The Jess sites were also correlated to the J-04, 120-ft tower. J-04 and J-08 

are at opposite ends of the study area (see Figure 2-3). Table 3-2 lists the 

correlation coefficients to these two sites. Sample size at all sites was 102 

data points. In addition, the table lists the correlation of all sites to 

their adjacent site. The table shows that the mean correlation coefficient to 

adjacent sites was 0.98, which is excellent. The mean correlation coefficient 

to Site J-08 was 0.89. This analysis on Jess was done as part of the QA 

process. Poor or fair correlations may be indicative of invalid data points.

The data listed in Table 3-2 are plotted on Figures 3-2 and 3-3. Figure 3-2 

shows the correlations to J-08, and Figure 3-3 shows the correlations to 

J-04. Both figures show the areas of high correlation in the vicinity of the 

reference tower used. Well-exposed sites such as L-3, L-5, and C-10 through 

C-14 show good correlations to both towers. Figure J-2 shows that there are 

two areas wi th relatively low correlation coefficients to J-08. These two 

areas are downwind of hills on the adjacent ranch. The hills are marked with 

"X". Evidently, the hills act as obstacles to the flow. The low correlations 

at these sites indicate a relatively high degree of variability in the wind in 

these two small areas. Site F-12, in the northern area, had the lowest correlation coefficient to Site J-OB. 

Additional analysis was done to determine the effect of inversion height on 

the degree of correlation. Inversion height data were collected on the Souza 

Ranch by Howden Wind Parks Inc. These data were made available by Howden. 

The analysis showed that for low inversion heights, with an inversion top 

below 1000 ft MSL, the correlation coefficient at F-12 drops to 0.56. However, 

when the inversion top is above 1000 ft MSL, the correlation coefficient jumps 

to 0.91. For comparison, site M-13 was analyzed, which is in the northeast 

portion of the Jess study area and not downwind of the 67B-ft hill. This site 

has a correlation coefficient of 0.97 for both low and high inversions, so the 

inversion has no effect on the correlation at this site. This exercise illustrates the combined effect of the low inversion and the topography. When the 

inversion is low, the wind at sites such as F-l2 is highly variable; this 

variability is a local effect, not seen at J-OB. This variability may be 

caused partially by wave activity within the inversion. The inversion rises 

and falls, and as it does, flow over the 67B-ft hill may be interrupted. The 

result could be that the wind might come in spurts downwind of this hill 

whenever the right combination of inversion height and wave activity occurs. 

When the inversion is higher the flow over the entire Jess Ranch is deeper. 

This leads to a more homogeneous wind resource over the ranch because the 

hills upwind do not obstruct the flow significantly.

This type of analysis was not done on Souza for two reasons: (1) the correlation coefficients to the reference tower were all quite high on Souza, and 

(2) the mean height of the inversion was considerably higher during the Souza 

free-flow period than it was during the Jess period. It is believed that the 

higher inversion during the Souza study is responsible, in part, for the

Tables 3-3 and 3-4 are joint-frequency distributions of wind speed and direction for sites S-13 and J-08, respectively. The data are grouped in 5-mph 

speed bins and 5° direction bins. Table 3-3 shows that wind directions ranged 

from 210° to 255°, south-southwest through west-southwest. Table 3-3 also 

shows that almost all the data fall in a 15° band from 220° to 235°. This is 

typical of spring/summer flow at site S-13. The table shows that most of the 

hourly mean speeds were between 20 and 30 mph.

hours of data, so the typical diurnal pattern may not be reflected in the 

data. The data from S-13 show the typical diurnal pattern of an Altamont 

site: highest winds just before midnight and lowest winds around noon. The 

data from the midday lulls at J-08 on October 2, 3, and 10 were deleted from 

the data set. Thus, J-08 does not show this pattern. 

A complete listing of the diurnal mean speeds at all sites can be found in 

Appendix D. These summaries are interesting because they allow a comparison 

of different sites' diurnal patterns and mean speeds. 

3.5 Vertical Shear 

In all, five two-level towers were available for this study, three on Jess and 

two on Souza. Vertical wind shear is often expressed as an exponent, alpha. 

Normally, in neutral atmospheric stability in areas of flat terrain, alpha is 

equal to 1/7 or about 0.14. Because of the inversion (which results in high 

stability) and the complex terrain, vertical shear in the Altamont Pass varies 

considerably from this value and is often less than 0.14. In the Altamont 

Pass, alpha values are generally very low on well-exposed ridges and higher at 

sheltered sites. The low values on well-exposed sites are because of speed-up 

effects near the ground. 

Alpha has been calculated for each hour of data at all five towers. Table 3-6 

is a diurnal summary of these data. (Note that the units in the table are 

"100 or %," so all values have been mUltiplied by 100. Thus, an alpha of 14.0 

in the table is actually 0.14.) The table shows that all five towers have 

alpha values below 0 .14. On the Jess Ranch, the mean of the alpha values 

ranged from 0.114 at site J-18 to a low of 0.058 at J-19. Site J-19 is on a 

well-exposed knoll, which helps explain its lower shear. 

There is no clear diurnal pattern shared by all si tes. J-18 and J-19 have 

lower shear in the midday than at night. Shear often increases after sunset 

as the lack of thermal instability creates less downward mixing of momentum. 

Because of the lack of mixing at night, flow lifts or separates from the 

ground, resulting in stronger shear. This phenomenon has beeni'tiiscussed quite 

extensively in meteorological and air-quality literature. 

The Souza sites also have mean alpha values below 0.14. In fact, site S-27 

has a mean shear close to zero, indicating that wind speeds are the same at 

both levels. Site S-13' s shear is larger, 0.075, and is about half the "normal" value. 

As noted in Section 2.2.1, there were two turbine anemometer heights on the 

Jess Ranch: 35 and 50 ft AGL. The vertical shear measured at the three Jess 

two-level towers suggests that the speed difference between 35 and 50 ft would 

be 2%-4%. 

3.6 Wind-Speed Frequency Distribution and Theoretical Energy 

Theoretical energy production is calculated by integrating the measured frequency distribution over a given time period and by using a power curve. This 

calculation has been done for the two reference sites, with the Nordtank power 

curve. In the calculation, the power curve has been adjusted to 97% of sealevel density, which is a close approximation based on the altitude and temperature. Wind-speed data at S-13 were collected at hub height, so no shear

adjustment is necessary. J-08 data were collected at 50 ft, which is 22 ft 

below hub height. However, based on the excellent exposure of J-08 (on a 

bluff), the shear between 50 and 72 ft AGL is probably negligible; therefore, 

no correction has been made. 

Tables 3-7 and 3-8 are the distributions for S-13 and J-08, respectively. The 

tables show that theoretical energy at these sites during the free-flow period 

was about 4300 kWh at S-13 and about 4700 kWh at J-08.

Theoretical energy at J-08 was slightly higher, partly because of the longer 

integrating period (102 hours versus 94 hours). Thus, the two periods were 

quite similar in energy content at these two sites. The mean wind speeds were 

nearly identical also. The data periods in these two tables are not identical 

because the free-flow measurements took place on different dates on these two 

ranches.

3.7 Speed and Energy Ratios 

The principal analysis tool of this report was the calculation of speed ratios 

between the reference site and all other sites. Ratios have been calculated 

for the entire data set and for a number of subsets. The subsets were based 

on stratification by a third parameter. The stratifications were done by the 

following: 

1. Wind direction at the reference site 

2. Wind speed at the reference site 

3. Day versus night hours 

4. Data period (at Jess, where there were two periods). 

Theoretical energy ratios were also calculated for the entire data set, using 

the Nordtank 65-kW power curve. 

After these various ratios were calculated, the data were plotted on topographic maps, and isopleths were drawn. The maps are an excellent vehicle for 

presenting this large amount of data, as the wind speed ratio patterns are 

quite apparent, when plotted out. In some cases, the ratios of a particular 

stratification class did not reveal any difference in overall pattern from the 

entire data set. In these cases, the maps are redundant and have not been 

included in this report. 

3.7.1 Souza Ranch Ratios 

Table 3-9 lists the speed ratios to S-13 for the various stratifications, as 

well as the energy ratios for the entire "data set. Reviewing Table 3-9 reveals 

that stratification by wind direction changes the ratios from the entire data 

set; however, stratification by speed and time of day shows fewer changes. 

There are four ratio maps included in this section: 

l. Speed ratios to S-13 for the entire data set 

2. Energy ratios to S-13 for the entire data set 

3. Speed ratios for wind direction band 210°-226° 

4. Speed ratios for wind direction band 226°-255°. 

Before reviewing these figures, it is useful to look at Figure 2-2, the topographic map of the Souza Ranch and surrounding terrain. Notice the location 

of the canyon aligned with the southwest flow that intersects the lower left 

(southwest) corner of the study area. 

Figure 3-4 is a plot of the speed ratios to S-13 for the entire data period. 

The wind speeds were quite uniform, except at G9. Almost all the site ratios 

were within a range of 90% to 110% of S-13. There are two high-wind areas: in 

the west area near G2 and F2-F8, and in the east area around 011 and 013. The 

first area is on a ridge downwind of the principal canyon axis, as mentioned 

above. The second area is a lower ridge jutting into a small drainage canyon 

(also aligned southwest). The areas with speed ratios of 100% or higher have 

been lightly shaded on the Souza maps. All sites with ratios above 100% are 

on ridges that intersect or jut into small drainage canyons, aligned with the 

prevailing flow. Turbine G9 is in a low-wind area that appears to be sheltered by the terrain immediately west of it.

Figure 3-5 is a plot of the theoretical energy ratios for the entire data 

period. The pattern is the same as that of Figure 3-4. Note that no shear 

adjustments were made to correct the 35-ft data to hub height (72 ft). 

Vertical-shear data for the Souza sites were discussed in Section 3.5. As 

mentioned-, site S-13' s shear was about one-half the "normal" value of 0 .14 

(for flat terrain) and S-27's shear was about zero. At sites that are not on 

the tops of well-exposed ridges, shear values may be close to 0.14. This is 

probably true at many of the "E" sites, which are on terrain that slopes 

gently down behind a ridge. Therefore, the energy ratios on Figure 3-5 may be 

artificially low at these sites. However, trying to estimate wind shear at 

individual sites is difficult; the resulting errors could be larger than if 

simply presenting the data as-is. 

Figure 3-6 is a plot of speed ratios for the more south-southwesterly winds 

(210°-226°). The ratios are about 3% higher overall than on Figure 3-4, but 

the general pattern is the same. Figure 3-7 is a plot of the speed ratios for

the more west-southwesterly winds (226°-255°). The ratios are about 2% lower 

overall than those of Figure 3-4 and 5% lower than those of Figure 3-6. 

3.7.2 Jess Ranch Ratios 

Table 3-10 lists the speed ratios to J-08 for the var~ous stratification 

classes, as well as the energy ratios for the entire data set. The speed 

ratios are for anemometer height and have not been normalized, except for 

those for site J-04. The ratios from the four sites that had some invalid 

data points are calculated from the data sets that include the surrogate data. 

As with Souza, the stratification by windcdirection changes the ratios more 

than does stratification by wind speed or time of day. The first data period, 

October 1-3, was characterized by somewhat weaker flow, and it also shows 

numerous changes in the speed ratios relative to the entire data set. Thus, 

there are five ratio maps included in this section: 

1. Speed ratios to J-08 for the entire data set 

2. Energy ratios to J-08 for the entire data set 

3. Speed ratios for wind direction band 210°-247° 

4. Speed ratios for wind direction band 247°-262° 

5. Speed ratios for the October 1-3 data period. 

Before reviewing the figures, it is useful to refer back to Figure 2-1 to 

study the upwind terrain. Notice the locations of the canyons aligned with 

the southwest flow, upwind of the ranch. Two large canyons and one small canyon should be noted. The largest canyon intersects the southern border of the 

study area and continues southwest for two miles, through sections 35 and 2. 

A second large canyon, which contains the southern lanes of Interstate 580, is 

west of the northern part of the study area. A small, third canyon can be seen 

in the southeast portion of Section 26. The canyons are marked with arrows. 

One additional terrain feature is the 681-ft hill upwind of Jess just west of 

the area marked "Cayley." This is the same hill discussed in Section 3.2.2, 

the Jess correlation discussion. 

Figure 3-8 is a plot of the speed ratios to J-08. All ratios are based on 

data from 35-ft or 50-ft levels with the following caveats. 

1. J-04 is adjusted from 120 ft to 50 ft using an alpha of 0.10. This value 

of alpha is considered a good estimate because J-04 is located in a slight 

depression. This terrain feature would result in a higher alpha than that 

measured at nearby site J-19, which has an alpha of about 0.06. 

2. J-19 data ~s actually from 40 ft (unadjusted). 

3. J-08 data ~s actually from 50 ft (unadjusted). 

4. Ratios for the 35-ft turbine anemometer are adjusted to the 50-ft level 

using an alpha of 0.10. Data collected on turbines on the northern half 

of the ranch were at 35 ft, versus 50 ft on the southern half. It is 

possible that using an alpha of 0.10 could yield a speed ratio error of 

±3% based on the expected range of shear values at these sites. Using an 

alpha of 0.10 is considered a good compromise based on data from J-17 and 

J-18.

Figure 3-8. Normalized Speed Ratios {X> to J-08 for All Hours 

36 
STR-3404 

S=~I. 

Note that almost all ratios are less than 100%. This IS because of site 

J-08's excellent exposure. J-08 is situated on a bluff, which juts into the 

large canyon that Interstate 580 runs through. J-08 is exposed to this channel, which is oriented parallel to the west-southwest flow. There are three 

relatively high wind areas; one around J-08 (extending downwind of it), one in 

the southern part of the study area at J-19, and another in the southern part 

of the study area (around H-1, H-2, C-IO, C-12, and C-14). These areas are 

aligned with the large canyons discussed previously. A fourth, smaller area 

of relatively high winds can be found near £-10 and E-22. This area is aligned 

with the third small canyon discussed previously. A relatively low wind-speed 

area can be found around G-l, G-3, and G-8. This area appears to be blocked 

by the 681-ft hill to the immediate southwest. Recall that this is close to 

the area with low correlation coefficients discussed in Section 3.2.2. Limited 

analysis shows that speed ratios at these low-wind sites increase with 

increased inversion height. The increase in speed ratios is on the order of 

10% when the inversion top is above 1000 ft MSL. 

It is interesting to note that the range of ratios on Jess is considerably 

larger than that of the ratios on Souza. The Jess study area is larger than 

Souza, but more homogeneity was expected because of its flatter terrain. 

Analysis of the inversion data collected on the Souza Ranch, as well as at the 

Oakland Airport, which is about 30 miles west of the Altamont Pass, shows that 

the mean inversion height was several hundred feet lower during the Jess 

free-flow period. Because of the interaction of the terrain with the inversion, the lower inversion heights during the Jess study are believed to be 

responsible, in part, for the wider range of ratios on the Jess Ranch. 

Figure 3-9 is a plot of the energy ratios to J-08. Note that all sites except 

J-08 have been normalized to hub height (72 ft) using a vertical wind shear 

exponent of 0.10. Meteorological towers J-17, J-18, and J-19 use their 

hub-height sensors for this map. Tower J-04 has been adjusted (down) from the 

120-ft level. All turbines have been adjusted (up) from the 35-ft or 50-ft 

levels. Vertical wind shear has been discussed in Sections 3.5 and 3.7.1. In 

Section 3.5, it was shown that sites J-17 and J-18 had shear exponents of 

about 0.10. These sites have exposure that is representative of many of the 

si tes on Jess. They are in fairly flat areas, not on highly exposed knolls 

like J-08 and J-19. Using an alpha of 0.10 is a good compromise. Some sites, 

like turbines L-3 and L-5, probably have less positive shear because of their 

similar exposure to J-08. Thus, their theoretical energy production may be 

biased positively. Other sites, like G-1, G-3, and G-8, are downwind of a 

hill and probably have higher shear than 0.10. Thus, they may be negatively 

biased. As mentioned in Section 3.7.1, estimating individual sites' vertical 

shear is difficult, so the reader is cautioned that individual energy ratios 

on Table 3-10 and Figure 3-9 could be in error by as much as 10%. Figure 3-9 

shows a similar pattern to that of Figure 3-8, except that there is a wider 

range of ratios (the lows are lower). 

Figure 3-10 is a plot of the normalized (to the 50-ft level) speed ratios to 

J-08 for wind directions from 232° to 247°. The pattern is similar to that of 

Figure 3-8, except that many sites have higher ratios. This is especially 

true in the southern and central parts of the study area. The ratios in the 

northern area, around J-08, are unchanged.

Figure 3-10. Normalized Speed Ratios (X) to J-08 for Wind Direction Band 

23r-24r 

39 
STR-3404 

Figure 3-11 is a plot of the normalized speed ratios to J-08 for wind 

directions from 247 0 to 262 0

• On this figure, many of the ratios are lower 

than those on Figure 3-8. As in Figure 3-10, the largest swing occurs in the 

southern and central parts of the study area, with the northern area 

unchanged. A possible explanation is that in winds with a more southerly 

component (Figure 3-10) the large canyon near the southern part of the study 

area (see Figure 2-1) is more aligned with the flow. Thus, these areas get an 

additional boost and the ratios increase. With more of a westerly component, 

this canyon is not as well aligned and the ratios fall. 

Figure 3-12 is a plot of the normalized speed ratios to J-08 for the first 

study period. In this figure, the ratios in the center of the ranch drop 

considerably. This is especially noticeable around tower J-18 and the F, G, 

J, and K turbines. Sites at the northern and southern ends of the study area 

show little change relative to Figure 3-8.

SECTION 4.0 

CONCLUSIONS 

Wind-speed data were collected from two dense networks on two wind farms in 

the Al tamont Pass. The data were collected during typical spring/ summer 

conditions, with no turbines operating in the study areas. Data were analyzed 

to determine variability of the wind resource. The principal method for doing 

this was to calculate wind-speed ratios to a single reference location. 

The smaller test area, the Souza Ran~h, has moderately complex terrain. The 

topography slopes gently downward and is punctuated with some small ridge 

lines that trend perpendicular to the flow. In spite of the complex terrain, 

the data set revealed a fairly homogeneous resource. All sites were highly 

correlated to the reference tower, and the mean speed ratio was 98%. The 

range of speed ratios was 77% to 111%; however, all but two sites had ratios 

within a band from 90% to 110% of the reference. Site elevation appears to 

enhance the flow. A topographic pattern at least as significant as the 

elevation is a combination of ridges and canyons. Specifically, ridges normal 

to the flow that jut into drainage canyons, parallel to the flow, appear to 

have the highest wind resource. 

The Jess Ranch study area has slightly complex terrain. It slopes gently 

downward, with a few ridges and valleys oriented parallel to the terrain. The 

data set was not as homogeneous as the Souza data set. This may be due in 

part to the lower height of the subsidence inversion during the Jess study 

period. The average correlation coefficient between the reference site and 

the other sites was 0.89. Speed ratios ranged from 56% to 102%, with a mean 

ratio of 79%. The range of theoretical energy ratios was 40% to 104%. Thus, 

the ratio between the best and worst turbine's theoretical energy production 

is 260%. These turbines are separated by about a half-mile and an elevation 

difference of only 60 ft. The low speed ratios to J-08 were due to the excellent exposure of the reference site relative to the other sites. Site elevation does not appear to be a factor at this ranch. However, the topographic 

pattern observed at Souza was seen here as well. Sites on ridges that jut 

into drainage canyons, or that are downwind of drainage canyons, have the best 

resource. Conversely, a hill rl.Sl.ng 150 ft above the surrounding terrain 

appears to disturb the flow for a downwind distance of approximately ten times 

the hill height. The flow disturbance caused by the hill is accentuated by 

the subsidence inversion. When low inversion heights were measured, the sites 

downwind of the hill had lower correlation coefficients and lower speed 

ratios. The strong positive effect of the drainage canyons parallel to the 

flow may not have universal application. This is true in the Altamont Pass 

because of the shallow, stable flow under the inversion. In areas with deeper 

layers or higher instability, these canyons might not have such a dramatic 

effect.

FOR THE SOUZA AND JESS FREE-FLOW STUDIES 

A.1 Summaries for the Souza Study, September 10-14, 1987 

September 10 

STR-3404 

On the afternoon of September 10, 1987, at 1600 Pacific Standard Time (PST), 

the semipermanent, subtropical Pacific surface high-pressure area was centered 

southwest of San Francisco at 32°N 132°W, with a central pressure of 1026 millibars (mb). A thermal low-pressure area, also a semipermanent feature, was 

centered over the southern tip of Nevada, with a central pressure of 1006 mb. 

The axis of this trough extended into southeast British Columbia. (Figure A-I 

has the important weather map features labeled.) The surface pressure gradient between the coast and the San Joaquin Valley was moderate at 3 mb. Aloft, 

southwest winds of 10 knots (kt) and a height of 585 decameters (Dm) were 

reported at the 500-mb level over Oakland, as the upper winds circulated 

around a low-pressure area with a central height of 574 Dm, located at 40 0 N 

134 Ow (see Figure A-2). The height of the marine layer was at a typical 

summertime level of 400 m. Winds at Souza were 20-30 mph at this time. 

Although the thermal trough axis was east of its usual position, and extended 

much farther north than it normally does, this was more or less a typical 

summertime weather pattern over the western United States. 

September 11 

At 0400 PST on September 11, surface high pressure was centered at 33°N 137°W, 

with a central pressure of 1025 mb. The thermal low was centered over southwest Arizona, with a central pressure of 1005 mb, and the axis continued east 

of its normal position and extended through Nevada, Oregon, and into eastern 

Washington (see Figure A-3). The surface pressure gradient from the coast to 

the valley at this time had diminished to 2.0-2.5 mb. The 500-mb low moved 

eastward to 40 0N 130 oW. At Oakland, the wind at 500 mb had increased to 15 kt 

out of the southwest, and the height of the 500 mb surface had dropped 5 Dm 

(which is greater than the fall that normally occurs during that part of the 

day) to 580 Dm (see Figure A-4). The marine layer at this time continued at a 

depth of about 400 m. Winds at Souza had increased slightly to 25-30 mph. 

At 1600 PST, the thermal low center had deepened to 1002 mb and moved into 

southeastern California, with the trough axis extending into eastern Washington. Along this axis, there was another low center of 1005 mb in central 

Nevada, and one of 1007 mb in northeast Oregon (see Figure A-S). These last 

two centers were probably due more to atmospheric dynamics rather than surface 

heating. The surface pressure gradient had increased to 3.0-3.5 mb. At 

500 mb, the upper level low moved southeast toward the area and intensified 

slightly to 573 Dm at 38°N 128°W (see Figure A-6). This caused the winds at 

this level to back down to the south and increase to 20 kt above Oakland, and 

the level of the SOO-mb surface dropped to 577 Dm at a time of day when it 

normally rises. It also allowed the marine layer to deepen to 800 m. The 

winds at Souza had increased to 25-35 mph in a weather pattern that is quite 

common in spring but occurs infrequently in the summertime.

STR-3404 

S=~I.' 

September 12 

At 0400 PST on September 12, the Pacific high-pressure area was centered at 

35°N 150 oW. The thermal low had a central pressure of 1003 mb and was centered over southern Nevada; the axis extended southward into extreme northwestern Mexico and northward into eastern Oregon (see Figure A-7). The surface pressure gradient had slackened to about 2 mb. The 500-mb low continued 

its southeast trek to a position at 35°N 125°W, and the central pressure 

dropped to 570 Dm. At Oakland, the 500-mb winds became southeast and diminished to 5 kt, while the level of the 500-mb surface fell to 573 Dm (see 

Figure A-8). The marine layer was somewhat shallower, at 650 m. As the 

pressure gradient had diminished and the marine layer had become thinner, the 

winds at Souza had decreased to about 25 mph. 

At 1600 PST, the Pacific high-pressure area had a central pressure of 1025 mb 

and was located at 34°N 143°W. The thermal low was centered over southeastern 

California, with a central pressure of 1002 mb; a trough axis extended into 

the southern Sierra Nevada. A dynamic low-pressure center of 1000 mb was 

located in northwestern Nevada, and a secondary center of 1002 mb was centered 

over western Idaho (see Figure A-g). The pressure difference from the coast 

to the valley had increased to 3 mb. Aloft, the 500-mb disturbance intensified to 569 Dm and moved to a position just off the California coast at Point 

Conception. In response, the winds at that level became east-northeast above 

Oakland (see Figure A-I0). The marine layer continued at about the same depth 

at 700 m. The winds at the site also changed little, at 25-35 mph, in a West 

Coast weather pattern that is typical in the spring but quite unusual in the 

summertime. 

September 13 

On September 13, at 0400 PST, surface high pressure was centered at 32°N 

141°W, with a central pressure of 1025 mb. The thermal low-pressure system 

was gone, and dynamic low-pressure centers of 1004 mb and 1003 mb were located 

over southern Nevada and southwestern Idaho, respectively (see Figure A-II). 

The surface pressure gradient between the coast and the valley was about 2 mb. 

Aloft, the upper low moved into southern California; winds above Oakland were 

from the northeast at 10 kt, with the 500-mb surface measured at 574 Dm (see 

Figure A-12). With cyclonic curvature aloft, the layer of marine air deepened 

to 950 m. At Souza, the winds had diminished to about 20-25 mph. 

At 1600 PST, surface high pressure continued well offshore. The low-pressure 

center that had been over southern Nevada at 0400 PST was now centered over 

southern· Arizona with a central pressure of 1009 mb. The low over southwestern Idaho continued to be nearly stationary with a central pressure of 

1003 mb (see Figure A-13). The surface gradient between San Francisco and 

Sacramento had increased to 2.7 mb. At the 500-mb level, the upper low had 

moved into southern Nevada, and at Oakland, the 500-mb height had risen to 

581 Dm, with the winds becoming north-northwest at 15 kt. These winds were in 

response to the movement of the upper level low out of the area and the 

upstream ridge moving in behind it (see Figure A-14). With the upper air flow 

becoming anticyclonic, and the marine layer becoming shallower at 600 m, the 

winds at Souza decreased to 10-20 mph in the "spring-like" weather pattern. 

45 
STR-3404 

September 14 

At 0400 PST on September 14, high pressure at the surface was centered at 42°N 

l54°W, with a weak ridge extending into northern California and Oregon. Once 

again, the thermal trough was absent; but the dynamic low pressure center over 

southwestern Idaho continued, though weakening, with a central pressure of 

1010 mb (see Figure A-IS). " The surface gradient between the coast and the 

Central Valley had diminishe"d to 1.0-1.5 mb. The upper low was over southeastern Utah at this time, and the ridge that had been upstream 12 h earlier 

had just passed Oakland. Heights continued to rise at Oakland, as the 500-mb 

surface was measured at 583 Dm and the upper winds at Oakland were out of the 

northwest at 15 kt (see Figure A-16). The marine layer had deepened a little 

to a depth of 750 m. The winds ac Souza increased slightly to 15-25 mph. 

At 1600 PST, the surface high-pressure area was centered at 42°N l50 o W, and a 

surface cold front extended from southeastern British Columbia through eastern 

Washington and Oregon and northwestern California. The thermal low had 

reformed over southern California, with a central pressure of 1010 mb (see 

Figure A-ln. The surface gradient had increased to 2.0-2.5 mb. At 500 mb, 

heights continued to rise at Oakland to 587 Dm, and the upper winds were westnorthwest at 20 kt (see Figure A-18). The marine layer quickly became very 

shallow, with the base of the inversion reported at the surface at Oakland. 

The winds at Souza at 1300 PST, when the study ended, were 15-20 mph. Although 

the weather was in the process of returning to normal summertime conditions, 

it was still in a springtime weather pattern. 

A.2 Summaries for the Jess Study, October 1-3 and October 7-10, 1987 

October 1 

On the afternoon of October 1, 1987 at 1600 PST, the semipermanent, subtropical Pacific surface high-pressure area was centered southwest of San Francisco 

at 29°N 130 o W, with a central pressure of 1019 mb. A thermal low-pressure 

area of 1008 mb was centered over the Imperial Valley, with a trough axis 

extending northward over the Central Valley, through western Oregon, and into 

western Washington (see Figure A-19). The surface pressure gradient between 

the California coast and the Central Valley at this time was rather large at 

4 mb. Aloft, south-southeast winds of 15 kt, with a 500-mb height of 586 Dm, 

were reported at Oakland. The winds were the result of the circulation around 

an upper level high-pressure area with a central pressure of 588 Dm, located 

over southern Idaho (see Figure A-20). Because of the anticyclonic motion and 

high heights aloft, the layer of marine air was shallow at 300 m. Although 

the surface pressure gradient was quite large, the winds at Jess Ranch were 

only 20-25 mph because of the influence of the shallow marine layer in this 

typical summertime weather pattern. 

October 2 

At 0400 PST on October 2, surface high pressure developed a center of 1022 mb 

at 41°N 128°W and was starting to build inland over the Pacific Northwest 

behind a weak, diffuse, cold front. The thermal low had a central pressure of 

1011 mb and was located over the east coast of Baja California, with the 

trough axis extending northward through the San Joaquin Valley into the Sacramento Valley (see Figure A-21). The surface pressure gradient was still large 

46 
STR-3404 

at 2.5-3.0 mb. At the 500-mb level, heights continued to be high at Oakland, 

with 585 ~m reported. The wind at that level was out of the southwest at 5 kt 

in the circulation around a strong upper level low-pressure area that was 

centered in the Gulf of Alaska (see Figure A-22). As a result, the marine 

layer deepened to 500 m. With the pressure gradient weakening and surface 

high pressure building into the Pacific Northwest, the winds at Jess had 

diminished to 15-25 mph and would continue to decline and even become northerly during the day. 

At 1600 PST, surface high pressure was centered at 37°N 133°W, with a central 

pressure of 1026 mb and a weak ridge extending into the Pacific Northwest. 

The thermal low was centered over extreme northwestern Mexico, with a central 

pressure of 1010 mb, and the trough axis extended northward through southern 

California, the Central Valley, Oregon, and eastern Washington (see Figure A-23). The pressure gradient was a moderate 2.4 mb. Aloft, Oakland was 

sandwiched between high-pressure centers of 589 Dm at (36°N 132°W) and 591 Dm 

over Utah. The level of the 500 mb surface at Oakland had risen to 589 Dm, 

greater than the normal daytime rise (see Figure A-24). Winds over Oakland 

were light and variable, and the marine layer became quite shallow at 100 m 

under the influence of the strong high pressure aloft. At Jess, the winds 

that had become light northerly earlier in the day continued out of that 

direction, and they would not become southwest again until 1700 PST in the 

typical summertime weather pattern. 

October 3 

At 0400 PST on October 3, the Pacific high was centered at 38°N 135°W, with a 

central pressure of 1030 mb and a weak ridge extending over Washington and 

Oregon. The thermal low was centered in northern Baja California; the trough 

extended northward off the southern California coast to Point Conception, then 

inland over the coast range through the Sacramento Valley (see Figure A-25). 

The pressure gradient between the central California coast and the Central 

Valley had slackened to 1.7 mb at this time. At 500 mb, high pressure was 

centered at 38°N l29°W, with a center of 592 Dm (see Figure A-26). In response 

to the movement of the upper high toward the coast, the winds above Oakland 

had become northerly at 10 kt and the heights continued to rise to 590 Dm. 

The marine layer was very shallow at this time, less than 100 m. The winds at 

Jess that had been about 15 mph at 0300 had stopped completely at this time, 

and the study ended. The winds would later become northerly in a pattern that 

was developing the characteristics of a classic late summer/early fall coastal 

heat wave. 

October 7 

On the morning of October 7 at 0400 PST, the semipermanent, subtropical eastern Pacific surface high-pressure area was centered southwest of San Francisco 

at 27°N l30 o W, with a central pressure of 1020 mb. The thermal low-pressure 

area was located over the Mexico/Arizona border and had a central pressure of 

1008 mb, with a weak trough axis extending northwestward along the southern 

Sierra Nevada (see Figure A-27). The surface pressure gradient between the 

California coast and the Central Valley at this time was large at 3.5 mb. 

Aloft, a weak trough just offshore was spinning out of a deep upper level lowpressure area centered at 38°N 145°W with a central pressure of 551 Dm. This 

caused west-southwest winds of 20 kt, with a height of 581 Dm at the 500 mb 

47 
STR-3404 

level, over Oakland (see Figure A-28). Because of the approaching upper level 

trough anfl the west-southwest winds aloft, the summertime layer of marine air 

was a little deeper than usual at 500 m. With an ample marine layer and a 

strong pressure gradient, the winds at the Jess Ranch were quite high at 30-

35 mph. 

At 1600 PST, the Pacific high had moved toward California and was centered at 

30 0 N 127°W, with a central pressure of 1021 mb. The thermal low was nearly 

unchanged, with a weak trough over the southern Sierra Nevada (see Figure A-29). The surface pressure gradient between the coast and the San Joaquin 

Valley continued at about 3.5 mb. At the sOO-mb level, the weak trough that 

was offshore at 0400 was now over the Sierra, while the upper low had filled 

to 561 Dm and was now located at 39°N 141°W (see Figure A-30). In response, 

the winds at Oakland had become west-northwest at 20 kt, and the height of the 

sOO-mb surface had risen to 583 Dm. The depth of the marine layer continued 

at 500 m. The winds at Jess Ranch had decreased to 25-30 mph in the typical 

summertime weather pattern. 

October 8 

At 0400 PST on October 8, surface high pressure was centered at 26°N 130 o W, 

with a central pressure of 1019 mb. The thermal low was centered over southwest Arizona, with a central pressure of 1008 mb, and the axis was oriented 

along the southern Sierra Nevada, through the Sacramento Valley, and through 

northwestern California (see Figure A-31). The surface pressure gradient from 

the coast to the valley at this time was a moderate 2.0-2.5 mb. The sOO-mb 

low moved eastward slightly to 39°N 140 oW, with a central pressure of 560 Dm. 

At Oakland, the wind at 500 mb was out of the west-northwest at 15 kt, and the 

height of the sOO-mb surface remained 583 Dm in response to a weak upstream 

ridge just offshore (see Figure A-32). The marine layer deepened slightly to 

700 m. The winds at Jess were about 25 mph. 

At 1600 PST, the thermal low center had deepened to 1006 mb and moved into 

southeastern California, with the trough axis along the Sierra Nevada (see 

Figure A-33). The surface pressure gradient had increased rapidly to over 

3.5 mb. At 500 mb, the upper level low moved to 38°N 136°W, with a central 

pressure of 566 Dm. The axis of the weak ridge that had been offshore at 0400 

had just passed Oakland and was now approaching the Sierra, causing the upper 

winds at Oakland to back to the southwest at 10 kt (see Figure A-34). The 

winds at Jess continued at 25 mph in the typical summertime weather pattern. 

October 9 

At 0400 PST on October 9, the Pacific high-pressure area was centered at 2s o N 

133°W. The thermal low had a central pressure of 1008 mb and was centered 

over the California-Arizona border, with the axis extending northward along 

the west side of the Central Valley, into northwestern California, and along 

the Oregon coast. A dynamic surface low (a reflection of the low in the upper 

atmosphere) with a central pressure of 1010 mb was centered at 36°N 13s oW (see 

Figure A-3s). The surface pressure gradient had slackened to 2.0-2.5 mb. The 

sOO-mb low continued its slow eastward trek to a position at 37°N 13s o W, with 

a central pressure of 565 Dm. At Oakland, the sOO-mb winds continued out of 

the southwest and increased to 20 kt while the level of the sOO-mb surface 

fell to 578 Dm (see Figure A-36). The marine layer was deep at 700 m. As the 

48 
STR-3404 

pressure gradient had diminished, the winds at Jess had decreased slightly to 

20 mph. 

At 1600 PST, the Pacific high was ill defined while the thermal low was centered over southeastern California, with a central pressure of 1008 mb, and 

the trough axis extended northward along the Sierra Nevada. A dynamic lowpressure area was centered over the Pacific at 34°N 132°W, with a central 

pressure of 1010 mb (see Figure A-37). The pressure difference from the coast 

to the valley had increased to 2.5-3.0 mb. Aloft, the 500-mb low-pressure 

area was now situated at 34°N l32°W, directly above the surface low, with a 

central pressure of 567 Dm. In response-; the winds at that level became 

southerly at 25 kt above Oakland (see Figure A-38). The marine layer was 

somewhat shallower, at a depth of 550 m. The winds at Jess increased slightly 

to 25 mph in a West Coast weather pattern that is typical in the spring but 

occurs infrequently in the summertime. 

October 10 

On October 10 at 0400 PST, surface high pressure was centered at 30 0N l22°W, 

with a central pressure of 1017 mb. Surface low pressure was centered at 34°N 

131°W with a central pressure of 1010 mb. The thermal low was centered near 

Yuma, Ariz., with a central pressure of 1012 mb. The thermal trough axis 

extended out of the low, -up the southern Sierra Nevada, through the Sacramento 

Valley, and into the California-Oregon border region (see Figure A-39). The 

surface pressure gradient between the coast and the valley had decreased 

significantly to about 1.5 mb. Aloft, the upper low was directly above the 

surface low at 34°N 13l o W, and Oakland had south-southeast winds of 30 kt at 

500 mb, with a height of 578 Dm reported (see Figure A-40). With cyclonic 

curvature aloft, the layer of marine air deepened to 750 m. At Jess, the 

winds had diminished slightly to about 15-20 mph in the "spring-like" weather 

pattern.

16. Abstract (Limit: 200 words) This report is one of a series of such documents that present the findings of field tests conducted under the Department of Energy's (DOE) 

Cooperative Field Test Program with the U.S. wind industry. The report provides the 

results of a study to collect data at two windfarms. The two wind turbine arrays, 

located in the Altamont Pass east of San Francisco, were instrumented with anemometers and a central monitoring computer. To. obtain a high spatial density of windspeed measurements, every other turbine in both arrays was instrumented. Wind-speed 

data were collected over a period of four days during the summer high-wind season 

with all turbines shut down. The resultant data set was analyzed to determine the 

spatial variability of the wind resource 1n the two arrays. Because no turbine 

wakes were present, variation 1n the flow was caused by the interaction of the flow 

with the terrain and was not a function of turbine wake interaction •. The free-flow 

data sets can be used by other researchers to refine numerical free-flow computer 

models. The data sets will be used to fine tune and validate these computer models. 

In addition, the free-flow data will be compared to results of a wake energy deficit 

study also under wayan these turbine arrays.
