摘　　要：通过常规气象资料、卫星云图及地面加密观测资料的诊断分析发现，在影响河北产生“９６．８”特大暴雨的两个中－α尺度云团中，有６个地面中尺度雨团（１小时降雨量≥１０ｍｍ，生命史≥３小时）先后形成，与之伴随的有多个地面中尺度系统，它们的形成及活动、发展都与地面湿斜压锋区及地面辐合场的分布有重要关系。After diagnosing the operational meteorological data,the satellite cloud pictures,and the intensive surface observational data,it was found that there were six surface mesoscale rain clusters (1 hr rainfall ≥10mm,life cycle ≥3 hr) formed in succession in the two meso α cloud clusters causing the torrential rain in Hebei in August 1996.And,associated with the clusters,there were several surface mesoscale systems closely related to the surface moist baroclinic front and the surface convergency in their development.
