Content:
pressure patterns, frontal systems, and temperature and humidity conditions reported by the applicant by comparing them with standard references. ` Verify the applicant’s description of the role of synoptic scale and mesoscale atmospheric processes on local (site) meteorological conditions by comparing it with the descriptions provided in standard references and the reviewer’s knowledge of the area. (2) Examine the regional meteorological averages and extremes, including severe weather phenomena and air quality conditions, to establish that the data represent site conditions by comparing ` concurrent offsite and onsite data (e.g., monthly averages of wind speed, wind direction frequency, and precipitation, and monthly averages and diurnal variations of temperature and humidity) ` offsite data for the concurrent period of onsite data with long-term (about 30 years) offsite data ` the locations of the stations with respect to major topographic features and airflow patterns (e.g., valley flow, land-sea (lake) breeze circulations, principal storm tracks). (3) Evaluate the local (site) meteorological parameters and topographic descriptions of the site area to establish that the data represent conditions at the site and its immediate vicinity by examining the location of the onsite meteorological tower (and other local sources of meteorological data) with respect to local topographic characteristics that could impact local airflow patterns (e.g., local circu- lation conditions such as “drainage flow”) and meteorological parameters such as temperature and humidity. October 1999 2.7-9 NUREG-1555 (4) Determine if the regional and local meteorological data are appropriate as bases for the applicant’s evaluation of potential changes in normal and extreme values, severe weather phenomena, and air quality conditions resulting from station construction and operation. (This information may be cross- referenced from Chapter 5.0 of the applicant’s ER.) (5) Analyze the
