| 摘 要： | 1998年6月江西特大降水过程的环流特征与历年重大连续暴雨过程不同，500hPa形势对连续暴雨的形成并不很有利，但是，强盛的中低层西南急流、穗定的中低层切交、经常存在的地面辐合线为这次降水提供了有利条件，在这样的条件下，降水的热力作用非常突出。

| Abstract: | In this paper, the amrence between the circulation feature of heavy rain process in June l998 Jiangxi and former continuous heaVy ndn procese is shown. The pattern of 500 hPa is uilfavourabe to the formation of colltinuous heavy bon. But poweful southwest jet and stabe sbear on the mesosphere and the the lower layer, and constan existed conveopnce line on the grdund provide favourabe condition for the fallout. On this condition, thermodynmaic effect is very outstanding to the fallout. |
