摘　　要：本文利用北京、石家庄等地的天气雷达连续观测回波资料,同步气象卫星提供的每3小时的卫星云图资料,华北地区每小时航空地面观测资料,以及北京、天津和河北省与山东省部分地区气候站提供的每小时降水资料,对1981年7月3—4日冷锋云系前暖区内中尺度回波系统的形成和发展的特征及其与暴雨的关系进行了分析。Based on the following data:the continuously observed radar echo data from Beijing,Shiji-azhuang,Dezhou,etc.,3-hourly satellite cloud pictures from GMS;hourly aviation surface obser-vations in North China;and hourly precipitation records taken from climatological stations in Bei-jing,Tianjin and some regions of Hebei and Shandong Provinces,analysed in this paper are thecharacteristics in the formation and development of the mesoscale echo system in the warm sectorahead of cold front during 3—4 July 1981 are analysed,as well as Its relationship with heavyrains。
