中文摘要: 分析了1996年8月3～5日河北省西南部致洪暴雨最大时段的卫星云图、雷达回波、地面风场及θse场的分布特征。结果发现，中－α尺度云团中的中－β和中－γ尺度云团不仅可使降水增幅，而且可以直接引起强降水产生；另外湿中性结构有利于特大暴雨的产生和加强。
中文关键词: 台风外围，特大暴雨，中小尺度，结构特征
Abstract:The distribution characteristics of satellite picture,radar echo,surface wind field and θse field were analyzed in order to in vestigate the very heavy rain occurred in the southwest of Hebei province in August 3～5，1996.The results show that meso-β and mesoγ cloud clusters in meso-αare able to result in not only the precipitation enchancing but also the bursting of severe precipitation.In addition,the wet neutral structure is beneficial to the emerging and strengthening of very heavy rain.
