摘　　要：通过对发生于长江中游地区两个中 -β尺度对流云团引起的特大暴雨过程的分析 ,探讨中 -β尺度对流云团产生强降水的条件 ,研究其变化规律 。An analysis of the heavy rain over the Changjiang River basin during 21—22 July 1998 was made.It is mainly to inquire into the problems with the genesis and development of the meso β scale convective systems which caused severe convective weather.The results show that the environmental conditions,especially the interaction between the upper level and lower level jets for the formation of deep convection is very important.
