| 摘 要： | 2001～2007年初夏孟加拉湾共发生了6次风暴过程,结合风暴活动期间曲靖地区的降水概况,应用micaps常规气象资料和物理量场对这6次过程的环流背景及水汽、动力条件展开分析,结果表明:初夏孟湾风暴影响曲靖降水有3个较典型的环流类型,即与冷空气配合型、孟湾风暴云团北上引发强对流降水型以及孟湾风暴登陆减弱变性成南支东移影响型;孟湾风暴活动期间,90°E～120°E,15°N～30°N区域存在位置基本对应的东北-西南向强西南风速带、水汽通量大值带和强水汽通量辐合带,说明风暴的活动为云南降水提供了充足的水汽和动力条件。

| Abstract: | Six storms occurred over the Bay of Bengal(BOB) in early summer during 2001～2007.Based on the micaps conventional observations,we analyzed the atmospheric circulation backgrounds,moisture and dynamic conditions of the six storms and their impacts on the precipitation in Qujing.The results show that,in early summer,there are mainly three types of the BOB storm influencing Qujing rainfall,namely,cold air involved pattern,northward progress of the BOB storm to arouse deep convection precipitation and eastward ... |
