| 摘 要： | 通过卫星云图、大尺度环流背景和动力条件分析了2007年7月7~8日临泉县迎仙气象观测站特大暴雨。结果表明:在有利的梅雨期环流背景下,由江淮切变线附近发生发展维持的中尺度对流系统,使迎仙站长达8 h持续处在-50℃东西向狭窄TBB低值带,云顶TBB梯度达2~3.5℃/km,导致安徽省日最大降水记录的特大暴雨发生。

| Abstract: | According to satellite cloud image,large-scale circulation background and dynamic condition,the torrential rainstorm occurring in Yingxian station in Linquan county in July 7th～8th,2007 was analyzed.The results showed that under the advantaged background of Meiyu season circulation,the mesoscale convective system occurred,developed and maintained near Jianghuai shear line,it made Yingxian station be in transmeridional narrow low value belt with TBB at-50 ℃ continuously for 8 h,the cloud top TBB gradient reached 2～3.5 ℃/km,which lead the happen of excessively heavy rainstorm with maximum daily rainfall record to occur in Anhui province. |
