Statistics on the tornado in evaluation area of nuclear power plant and weather characteristics analysis
摘要
Abstract
By means of tornado materials from 1971 to 2005,according to tornadoes spatiotemporal and geographical distribution, and weather system characteristics in evaluation area of Pengze nuclear power plant, statistical methods are adopted to investigate and analyze. The results show that： the survey area is about 23.58 square kilometers,including 5 provinces, 22 cities and 163 counties. There were totally 151 tornadoes,an average of 4.31 times a year,mainly in spring summer from March to August,most occurred in 16：00-19.00. Tornadoes mainly happened around the Yangtze River and Poyang Lake,and rarely appeared in mountain and hilly area. The following weather systems can lead to a tornado generation such as cold front, warm air mass, stationary front, squall line and tropical cyclone. Both low-level warm wet and dry cold in the middle and upper air is one of the basic conditions that can cause the tornado.关键词
