| 摘 要： | 通过对2000年及2003年发生在浙江省金华市的两次大暴雨过程进行对比分析,发现大暴雨的产生必然具备高能、高湿及强上升运动;主要影响系统是500 hPa低槽东移加深和低层切变南压,而对流层高层200 hPa和低层850 hPa大风核的同时东传是大暴雨发生的预兆。

| Abstract: | This article analysis two heavy rainstorm processes happened in Jinhua city of Zhejiang province in 2000 and 2003 ,It is found that high energy,high humidity and strong updraft are the necessary conditions for producing heavy rainstorms,and the main synopticsystems are westerly developing through on 500hPa and northerly shear in low troposphere.While the simultaneous moving eastwards of 200hPa shoot core and 850hPa shoot core is a sign of coming heavy rainstorm. |
