鄂东地区雷雨大风多普勒天气雷达回波特征

Characters of Doppler Radar Velocity on Intense Gust in the East of Hubei Province

摘要: 使用多普勒雷达速度场等资料,对2004—2005年发生在武汉附近五次灾害性大风过程进行了分析,同时,利用雷达风廓线产品(VWP)计算的0~1、0~3km的风垂直切变和风暴相对螺旋度(SRH)等物理量,分析了低层环境风垂直切变与中气旋存在的关系

Abstract: Using Doppler radar velocity field data the analyses were conducted on five gust processes happened near Wuhan from 2004 to 2005, and also on the relation between low-level wind vertical shear and mesocyclone usi
