摘　　要：应用卫星云图、地面加密记录和各种常规资料，通过对４个台风暴雨个例云图特征和物理量场的综合诊断，探讨低层风场扰动对暴雨云团的激发作用。结果表明，中低纬度两类不同性质不同尺度云系相叠加，并在叠加区内出现低层风场扰动，则预示着台风倒槽北部将有暴雨云团发展，将引起华东北部地区降水强度突然增幅。Using satellite cloud pictures and data from the intensive and conventional observation,the characteristics of the cloud pictures and the physical quentity field are comprehensively diagnosed. Then trigger actions of the disturbance of low-level wind field for cloud cluster with heavy rain are discussed.
