摘要
对１９８０～１９８３年梅雨期间安徽发生的６次暴雨过程，作了沿１１７．５°Ｅ的空间剖面图分析。结果发现，梅雨锋常不及地，在低层锋区特征不明显，而且在地面出现带状雷暴雨时，常在雨区南侧形成“雨成锋”。作者对雨成锋的形成和演变作了初步探讨，并对各阶段经圈环流特征进行了详细的分析。
Research is carried out of six rainstorm events during 1980～1983 Meiyu periods, oc-curring in Anhui based on the 1 17.5°E section, Evidence suggests that the Meiyu front is usuallyaway from ground without pronounced frontal features at low levels, and that a“precipitation-caused front”is often observed On the s outhsidewhen abeldikethunderstorm rainfall occurs inthe near-surface layer,Apreliminary study is undertaken of the genesis and evolution of the pre-cipitation-caused front alongside detailed analysis of meridional circulation features at variousphases.
