江西对流风暴触发系统与形成机制探讨

Discussion on triggering system and forming mechanism of convective storm in Jiangxi

利用常规天气图、中尺度分析图、卫星云图和雷达回波图等资料,通过个例分析方法,对江西对流风暴的触发系统与形成机制进行了初步分析,结果表明:冷锋、静止锋、850HPa切变线、850HPa能量锋、中尺度对流云团、中尺度地形辐合线、雷暴冷堆、冷出流边界和局地锋区是江西对流风暴的9种主要触发系统与形成机制。

By means of routine synoptic charts,meso-scale analysis charts,satellite cloud pictures and radar echo pictures,triggering system and forming mechanism of convective storm in Jiangxi were preliminary analyzed and summarized with case study method.Results show that the influential factors including cold front,stationary front,shear（850Hpa）,energy front（850Hpa）,meso-convective clusters,meso-topography convergence line,cold storm stack,cold effluent border and local frontal zone are mainly the storm triggering system and forming mechanism.
