摘　　要：本文利用高空常规资料,格距为150km,取λ_(max)=1500km的带通滤波器对长江三角洲地区的暴雨云团所处的环境场(包括风场,高度场和温度场)进行尺度分离,讨论中尺度扰动场与暴雨云团的关系。In this paper,wind field,height field and temperature field of heavy rain cloud cluster over Yangtze River Delta Region have been explored by bandpass filter techniques with the maximum response wave length fo 1500km and the grid length of 150km,using the conventional meteorological data (1000-100hPa). The relationship between the meso-sc,ale disturbance field and the heavy rain cloud cluster has also been discussed.
