中文摘要: 该文以长江三峡地区6个站1961—1994年10月—1月的逐日降水量来确定该地区发生区域性强降水的雨日，用同期的历史天气图分析产生区域性强降水的原因、影响系统和环流形势特征，归纳出长江三峡地区产生区域性强降水的6类环流型，并进行逐日反查，概括出两类环流型产生区域性强降水的预报指标。用1995年历史天气图和降水资料进行检验，并在1996年10、11两月进行试预报，结果可供参考。

Abstract:By using the precipitation data in the dry season from 19(51 to 1994 and the same time synoptic maps, the severe precipitation factors and features of circulation prior to the occurrence of the regional severe precipitation are analysed. Six circulation patterns are classified from numerous cases and the indexes of forcasting severe precipitation are discovered from the every day data.
The forecasting indexes of severe precipitation for two circulation patterns are given, which is proved to he practical value in the dry season severe precipitation occurrences in Sanxia on the Changjiang in recent two years.
