Analysis of Simulated Heavy Rain over the Yangtze River Valley During 11-30 June 1998 Using RIEMS

RIEMS' ability to simulate extreme monsoon rainfall is examined using the 18-month (April 1997September 1998) integrated results. Model-simulated heavy precipitation over the Yangtze River valleyduring 11-30 June 1998 is compared with the observation, and the relationships between this heavy rainfallprocess and the large-scale circulations, such as the westerly jet, low-level jet, and water vapor transport,are analyzed to further understand the mechanisms for simulating heavy monsoon rainfall. The analysisresults show that (1) RIEMS can reproduce the pattern of heavy precipitation over the Yangtze River valleyduring 11-30 June 1998, but it is shifted northwestwards. (2) The simulated West Pacific Subtropical High(WPSH) that controls the East Asia Monsoon evolution is stronger than the observation and is extendedwestwards, which possibly leads to the north westward shift of the heavy rain belt. (3) The Westerly jetat 200 hPa and the Low-level jet at 850 hPa, both of which are related to the heavy monsoon rainfall,are reasonably reproduced by RIEMS during 11-30 June 1998, although the intensities of the simulatedWesterly/Low-level jets are strong and the location of the Westerly jet leans to the southeast, which maybe the causes of RIEMS producing too much heavy rainfall in the north of the Yangtze River valley.

A Comparative Study of the Numerical Simulation of the 1998 Summer Flood in China by Two Kinds of Cumulus Convective Parameterized Methods

The NCC T63L20 model of the National Climate Center, China Meteorological Administration isemployed to simulate the 1998 summer flood, which mainly occurred in the region of the Yangtze River andNortheast China. For this study, two kinds of cumulus convection parameterized schemes are employed inthis model respectively. The simulations show that the Gregory parameterized scheme, which is still usedin the United Kingdom Meteorological Office routine model, simulates more reasonable rainfall amountand distribution compared to the Kuo-type scheme. Moreover, the Gregory scheme better simulates thetendency of general circulation than the Kuo-type scheme. On the whole, the Gregory scheme providesa good simulation of the main features of the seasonal precipitation and general circulation in China,although the simulated result still exhibits some departures from the observations.

Numerical Simulations of a Heavy Rainfall Case in South China

Using a double-parameter non-hydrostatic elastic three-dimensional model with detailed microphysicalprocesses, the authors simulate the heavy rainfall event in South China which occurred on 9 June 1998 andlasted for more than 3 hours. This case is a supercell, and the upward and downward drafts interact witheach other, which transfers rich water vapor at the converging position to upper levels, and the two draftstogether maintain the convective course. The vertical heating profiles and contributions to water matterof five kinds of micro-phase processes are revealed quantitatively in the results. Condensation releases themost heat, which is more than that of the absorption by evaporation and melting. The rain particles firstcome from the autoconversion of cloud particles, the warm-rain process; later from the cold-rain process,the melting of grauple particles. The precipitation intensity reaches 75 mm h-1 while its efficiency remainshigh. The total amount of rain is 32 mm, a value close to the observations of nearby stations.

Mechanism of Formation of the Ozone Valley over the Tibetan Plateau in Summer Transport and Chemical Process of Ozone

With the 3D chemical transport model OSLO CTM2, the valley of total column ozone over the TibetanPlateau in summer is reproduced. The results show that when the ozone valley occurs and develops, thetransport process plays the main part in the ozone reduction, but the chemical process partly compensatesfor the transport process. In the dynamic transport process of ozone, the horizontal transport process playsthe main part in the ozone reduction in May, but brings about the ozone increase in June and July. Thevertical advective process gradually takes the main role in the ozone reduction in June and July. The effectof convective activities rises gradually so that this effect cannot be overlooked in July, as its magnitudeis comparable to that of the net changes. The effect of the gaseous chemical process brings about ozoneincreases which are more than the net changes sometimes, so the chemical effect is also important.

Heat and Moisture Budgets during the Period of HUBEX/GAME in the Summer of 1998

By using the high-resolution GAME reanalysis data, the heat and moisture budgets during the period of HUBEX/GAME in the summer of 1998 are calculated for exploring the thermodynamic features of Meiyu over the Changjiang-Huaihe (CH) valley. During the CH Meiyu period, an intensive vertically-integrated heat source and moisture sink are predominant over the heavy rainfall area of the CH valley, accompanied by strong upward motion at 500 hPa. The heat and moisture budgets show that the main diabatic heating component is condensation latent heat released by rainfall. As residual terms, the evaporation and sensible heating are relatively small. Based on the vertical distribution of the heat source and moisture sink, the nature of the rainfall is mixed, in which the convective rainfall is dominant with a considerable percentage of continuous stratiform rainfall. There are similar time evolutions of the main physical parameters(〈Q1〉,〈Q2〉,and vertical motion ω at 500 hPa).The time variations of〈Q1〉and〈Q2〉are in phase with those of -ω500, and have their main peaks within the CH Meiyu period. This shows the influence of the heat source on the dynamic structure of the atmosphere. The wavelet analyses of those time series display similar multiple timescale characteristics. During the CH Meiyu period, both the synoptic scale(～6 days) and mesoscale (～2 days and ～12 hours) increase obviously and cause heavy rainfall as well as the appearances of the maxima of the main physical parameters. Among them, the mesoscale systems are the main factors.

Runoff Simulation Using Radar and Rain Gauge Data

The conceptual rainfall-runoff model TOPMODEL is used to simulate runoffs of the Meishan and Nianyushan catchments during the summers of 1998 and 1999 in the GAME/HUBEX (GEWEX Asia Monsoon Experiment/HUAIHE River Basin Experiment) project. The rainfall distributions are estimated by weather radar and rain gauge networks according to different methods. Observed and simulated runoffs are compared and analyzed for both catchments. Results show that(1) the runoff of the catchment is best simulated by radar data combined with rain gauge network data from inside the catchment, and (2) the rainfall estimated by radar adjusted by a few rain gauges outside the catchment can be used to simulate runoff equally as well as using the dense rain gauge network alone.
Application of Radar-Measured Rain Data in Hydrological Processes Modeling during the Intensified Observation Period of HUBEX

On the basis of Digital Elevation Model data, the raster flow vectors, watershed delineation, and spatial topological relationship are generated by the Martz and Garbrecht method for the upper area of Huangnizhuang station in the Shihe Catchment with 805 km2 of area, an intensified observation field for the HUBEX/GAME Project. Then, the Xin'anjiang Model is applied for runoff production in each grid element where rain data measured by radar at Fuyang station is utilized as the input of the hydrological model. The elements are connected by flow vectors to the outlet of the drainage catchment where runoff is routed by the Muskingum method from each grid element to the outlet according to the length between each grid and the outlet. The Nash-Sutcliffe model efficiency coefficient is 92.41% from 31 May to 3 August 1998, and 85.64%, 86.62%, 92.57%, and 83.91%, respectively for the 1st, 2nd, 3rd, and 4th flood events during the whole computational period. As compared with the case where rain-gauge data are used in simulating the hourly hydrograph at Huangnizhuang station in the Shihe Catchment, the index of model efficiency improvement is positive, ranging from 27.56 % to 69.39 %. This justifies the claim that radar-measured data are superior to rain-gauge data as inputs to hydrological modeling. As a result, the grid-based hydrological model provides a good platform for runoff computation when radar-measured rain data with highly spatiotemporal resolution are taken as the input of the hydrological model.
Diagnosis of the Heavy Rain near a Meiyu Front Using the Wet Q Vector Partitioning Method

A heavy rain process of the Changjiang-Huaihe Meiyu front (MYF) is diagnosed by the agency ofthe traditional Q vector partitioning (QVP) method to decompose the wet Q vector (Q) in a naturalcoordinate system that follows the isoentropes and by using the numerical simulation results of the revisedMM4 meso-scale model. The technique shows that the partitioned wet Q vectors can lead to a significantscale separation of vertical motion related to the torrential rain. The results not only verify the existingconclusion that different scales interact throughout the rainstorm but also indicate the largely differentroles of these scales during differing phases of the heavy rainfall on a quantitative basis. Specifically, duringthe developing stage, the large-scale plays a predominant role in forcing vertical motion, while frontal-scaleforcing is secondary; during the intense stage, the frontal-scale evolves into the primary factor of forcingvertical motion, whereas the large-scale forcing is minor and plays a diminishing role and can even beignored; and during the decaying stage, the large-scale once again serves as the main forcing of verticalmotion in such a way that the forcing of the frontal-scale decays quickly and is of secondary importance.Furthermore, the partitioned wet Q vectors are suggested to be more suitable than the total wet Q vectorfor evaluating the potential physical mechanism of rainstorm genesis. The first step is that the forcingof large-scale 2▽ · Q_s~* gives rise to the genesis of meso-scale 2▽· Q_n~* forcing; and then, accordingly as2▽· Q_n~* forcing increases, whereby the secondary circulation is reinforced, the intensity of the rainfall isstrengthened; and at last, the secondary circulation caused by 2 ▽· Q_n~* forcing is directly responsible forgeneration of the MYF heavy rainfall.

Spatial and Time Structure of a Gravity Wave in Horizontal Atmosphere of Heterogeneous Stratification

By the use of the WKBJ method combined with the characteristic line method, the asymptotic solutionof a gravity wave envelope in the atmosphere of horizontal heterogeneous stratification and time-varyingstratification is obtained. The solution shows that not only the variation of amplitude of the gravitywave but also the variation of wavelength and the width of the envelope are affected by the horizontalheterogeneity. As the wave envelope moves from a region of strong stratification to a weak one, thehorizontal wavelength will become shorter, the width of the envelope will narrow and its amplitude willincrease. The variation of stratification with time cannot lead to the variation of wavelength and envelopewidth, but the amplitude of the wave envelope will increase while the amplitude of the wave decreases intime.

Application of TRMM/PR Data for Numerical Simulations with Mesoscale Model MM5

Numerical simulations of two heavy rainfall cases in the Changjiang-Huaihe River basin are performed with TRMM/PR (precipitation radar) data incorporated into the PSU/NCAR meso scale model MM5.The mixing ratio of rainwater qr is obtained from the R-qr relation (R is the rainfall rate), and the mixing ratio of water vapor qv in the model is replaced by q'v=qv+qr. Then, TRMM/PR data are used to modify humidity analysis obtained from conventional radiosonde data, and sensitivity experiments (STE) are performed and compared to control experiments (CTL). Results show that both the heavy rainfall distribution and its maximum amounts from STE are improved compared with those from CTL.

河南熊耳山区的铁炉坪银矿定位于高级变质基底中的NE向断裂带中,是熊耳山脉状造山型金、银、铅锌矿床的重要组成部分.成矿作用包括了早、中、晚3个阶段,分别形成石英-黄铁矿,多金属硫化物和碳酸盐脉3类矿物组合.早阶段成矿温度大约为373℃左右, 成矿流体δD=-90‰, δ13CCO2=2.0‰, δ18O=9‰,来源较深; 晚阶段流体温度<203℃,δD=-70‰, δ13CCO2=-1.3‰, δ18O=-2 ‰, 属于浅源大气降水热液; 中阶段流体均一温度210～249℃,δD= -109‰, δ13CCO2=0.1‰, δ18O=2‰, 是深源与浅源流体的混合.对比讨论表明,熊耳山区的早前寒武纪变质基底、熊耳群火山岩和燕山期花岗岩类的三者之一或它们的混合物,均无法提供具有早阶段流体D-O-C同位素组成(高δ18O和δ13C,低δD)的成矿流体,表明早阶段流体来自栾川群和管道口群的碳酸盐-页岩-硅质岩建造的变质脱水作用.矿石硫同位素组成较低,铅同位素比值较高,同样不可能来自熊耳山的主要地质体,更不可能来自其下伏的地幔和下地壳,指示成矿物质和流体应主要来自栾川群和管道口群.尽管栾川群和管道口群地层的同位素地球化学研究尚待补充,铁炉坪银矿的同位素地球化学特征似乎只能借助碰撞造山成岩成矿与流体作用模式才能合理解释.即华南与华北古板块在中生代发生陆陆碰撞,包含栾川群和管道口群地层的板片沿马超营断裂向北俯冲到熊耳山之下,俯冲板片变质脱水诱发作为仰冲板片的熊耳山广泛发育Au、Ag等造山型流体成矿系统,最终导致铁炉坪造山型银矿的形成.
Applications of a Surface Runoff Model with Horton and Dunne Runoff for VIC

Surface runoff is mainly generated by two mechanisms, infiltration excess (Horton) runoff and saturation excess (Dunne) runoff; and the spatial variability of soil properties, antecedent soil moisture, topography, and rainfall will result in different surface runoff generation mechanisms. For a large area (e.g., a model grid size of a regional climate model or a general circulation model), these runoff generation mechanisms are commonly present at different portions of a grid cell simultaneously. Missing one of the two major runoff generation mechanisms and failing to consider spatial soil variability can result in significant under/over estimation of surface runoff which can directly introduce large errors in soil moisture states over each model grid cell. Therefore, proper modeling of surface runoff is essential to a reasonable representation of feedbacks in a land-atmosphere system. This paper presents a new surface runoff parameterization with the Philip infiltration formulation that dynamically represents both the Horton and Dunne runoff generation mechanisms within a model grid cell. The parameterization takes into account the effects of soil heterogeneity on Horton and Dunne runoff. The new parameterization is implemented into the current version of the hydrologically based Variable Infiltration Capacity (VIC) land surface model and tested over one watershed in Pennsylvania, USA and over the Shiguanhe Basin in the Huaihe Watershed in China. Results show that the new parameterization plays a very important role in partitioning the water budget between surface runoff and soil moisture in the atmosphere-land coupling system, and has potential applications on large hydrological simulations and land-atmospheric interactions. It is further found that the Horton runoff mechanism should be considered within the context of subgrid-scale spatial variability of soil properties and precipitation.

埃达克质岩与Cu-Au成矿作用关系的初步探讨

近来的研究发现,埃达克质岩与Au、Cu、Mo等浅成低温热液矿床及斑岩矿床有密切的关系.我们的研究表明:(1)我国的斑岩铜矿大多与埃达克质岩有关,如德兴、沙溪、多宝山、乌奴格吐山和新近发现的东疆土屋斑岩铜矿等,有些被划归与富碱侵入岩或A型花岗岩有关的斑岩铜矿,如玉龙,也具有埃达克质岩的地球化学特征;(2)华北地区的Au矿床大多与埃达克质岩有关,最典型的如胶东和小秦岭;(3)长江中下游地区的Cu、Au、Mo矿床的岩浆岩大多为埃达克质岩.埃达克质岩与成矿作用之所以密切相关,其原因在于它们在地壳深部形成的条件和环境类似,这就为Au、Cu、Mo等的找矿开辟了一个新的思路.埃达克质岩浆是玄武质岩石在高压、高温和含水条件下熔融形成的,上述条件有利于Cu、Au、Mo等金属元素溶解进入熔体.关于找矿方向,文中指出3点:(1)埃达克质岩发育的地区可能是矿床聚集的地区;(2)与消减作用有关的埃达克岩更有利于成矿元素的富集,对于中国来说,晚元古宙-古生代的古亚洲洋造山带内消减作用广泛发育,有巨大的找矿前景;(3)找矿工作应围绕埃达克质岩体及周围地质体进行.
