| 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、稳定的中低层切变、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: | The difference of the circulation feature between the continuous torrential rain events in June 1998 and the historical similar events in Jiangxi was described.The 500hPa pattern is unfavonrable to the formation of the continuous torrential rain.However,the prevailing southwest jet and stable shear in the mesosphere and the lower troposphere,and the convergence line existed usually on the ground provide a favourable condition for the precipitation events.Under this condition,the thermodynamic effect in precipitation is obvious. |
