中文摘要: 分析2002年6月6次强降水过程的逐时GMS-5红外云图TBB资料和加密多普勒雷达回波资料,结果表明:这6次大到暴雨天气过程都是在川滇低涡切变影响下,由中尺度系统造成的。在卫星云图上都是由MCC活动造成的,MCC云顶亮温都低于-75℃。大于40dBz的飑线、涡旋带状回波和中尺度絮状回波团直接产生这6次大到暴雨过程。
中文关键词: 中尺度对流复合体MCC，TBB，多普勒雷达回波
Abstract:By analysis of hourly GMS-5 infrared TBB image and intensive observation of Doppler radar, it indicated that the 6 heavy rain events were created by the mesoscale system due to the impact of the mesoscale and microscale low voxtex shear in Sichuan and Yunan. Mesoscale Convective storm Complex(MCC) in the TBB pictures likely occurred in the TBB low value area of ≤-75℃,and on the other hand,due to the squall line,vortex zonality echo and the mesoscale floccus echo on the Doppler radar echoes, likely occurred in the echo intensity area of ≥40dBz.
