| 摘 要： | 根据湖北省浠水核电站周边300 km×300 km区域范围内1964—2007年龙卷风资料,对龙卷风的时间分布和灾害特征进行了分析。结果表明：龙卷风有明显的时间分布,一年之中主要集中在春、夏两季,秋、冬季无龙卷风发生,以7月最多;一天之中,午后至傍晚最多,集中在16：00—18：59之间,龙卷风平均持续时间27 min。近44年,21世纪头7年中龙卷风出现最为频繁。龙卷风出现时,蒲福风力等级一般在10级以上,集中出现在12级;富士达风力等级集中出现在F0、F1级,F2级以上出现的几率较小。龙卷风多以自西向东方向移动,影响宽度平均1.20 km,平均带长21.66 km。龙卷风灾害主要是风灾,往往伴有冰雹、暴雨、雷击,破坏力极强。 |

| Abstract: | The characteristics of tornado events around the Xishui nuclear power plant of Hubei Province from 1964 to 2007 are analyzed based on the data from the area of 300 km×300 km around the nuclear power plant in the ways such as meteorological station records,climate impact assessment reports,etc.The results indicate that： there was apparent temporal distribution in those tornado events,such as daily,monthly,and decadal scale variation.The tornadoes concentrated mostly in spring and summer,especially in July,and occurred frequently from mid-day to early evening,especially at afternoon;however,there was seldom tornado occurred in autumn and winter.The average lasting time for all tornadoes is 27 min.During the past 44 years,tornadoes appeared most frequently in the first seven years of the 21st century.The wind speed grade is mostly 10 on the Beaufort scale,concentrated around 12.The most frequent moving direction of the tornadoes is from west to east,and the average affected width is 1.20 km,and the average affected length is 21.66 km.The most severe tornado-induced disaster is that induced by the extremely strong wind,which mostly accompanies hailstones,heavy rainfall,and lighting strikes. |
| Keywords: | tornado temporal distribution disaster characteristic wind level |
