【 摘 要 】

Wind speed and direction data have been collected by National Weather Service (NWS) Stations in the U.S. for a number of years and presented in various forms to help depict the climate for different regions. The Savannah River Technology Center (SRTC) is particularly interested in the Southeast since mesoscale models using NWS wind observations are run on a daily basis for emergency response and other operational purposes at the Savannah River Site (SRS). Historically, wind roses have been a convenient method to depict the predominant wind speeds and directions at measurement sites. Some typical applications of wind rose data are for climate and risk assessment; air pollution exposure and dose calculations; siting industrial plants, wind turbine generators, businesses, and homes; city planning; and air stagnation and high ozone concentration studies. The purpose of this paper is to demonstrate the overall relationships of wind patterns for NWS stations in the Southeast. Since organized collection of wind data records in the NWS developed rapidly in conjunction with the expansion of commercial aviation after World War II there are now about 50 years of wind speed and direction data available for a large number of NWS stations in this area. In this study we used wind roses for relatively short time scales to show the progression of winds diurnally and monthly to span a typical year. The date used here consist of wind records from 13 National Weather Service Stations in the Southeastern U.S. for approximately 50-year periods.
