摘要
本文选取了列为1970～1983年出现在珠江三角洲的范围最大的一次雹暴过程，从天气尺度环流背景、层结条件、抬升力、高低空急流等方面进行分析，探讨了在锋后对流层低层已明显降温的情况下出现大范围持续雹暴的原因。
A case of severe convective process. which is known the wildest one in the Delta Area of the Pearl River during the period of 1970 - 1983, was chosen to investigate the development conditions of severe convection. The analysis aspects include the circulationbackground, the stratification of the atmosphere, the lifting forces and the Jet streams in the lower and upper layers. This paper emphasizes to discuss the reason why the continued hail storms can develop in the wide post - frontal area where the temperature descends obviously in the lower troposphere.
