1991年7月江淮暴雨过程风──压场特征分析

AN ANALYSIS OF THE WIND-PRESSURE FIELD FOR THE HEAVY RAINFALL OVER THE CHANGJIANG-HUAIHE VALLEY IN JULY 1991

本文用1991年7月5－9日资料，计算了我国江淮地区持续暴雨期间的地转偏差的各种特征。结果表明：暴雨区及附近，上下层的地转偏差各不相同。这可能表明存在会引起暖区暴雨发生的一种动态的地转调整和适应过程。

Using the date of 5 - 9 July 1991. the geostriphic departures during the heavy rainfall over the Changjiang - Huaihe Valley are calculated. It is showed that the geostriphic departures are different between the upper level and the lower layer. It may implicates that a kind of moving geostriphic adjustment cause heavy rainfall over the warm area exists in the process
