摘　　要：利用湖南1979—1988年夏秋外场观测的资料,分析了积云雷达回波和降水的特征,建立了用雷达回波参数估算单站积云降水量、水层厚、总降水量和雨强的回归关系式,并用湖南积云降水资料和广东积云降水资料进行了检验。结果表明:这种估算积云降水的方法对我国南方的广大地区有一定实用性。The features of radar echo and rainfall of cumulus are analysed by using the field observa-tional data obtained in Hunan Province in summer and autumn,1979—1988.The regression rela-tions of radar echo parameters with the rainfall amount of single station,depth of raintall,totalrainfall amount and rainfall density are then established.The test of such relations using the cu-mulus rainfall data in Hunan and Guangdong Provinces indicates that they are applicable,to acertain degree,in estimating cumulus rainfall in the vast areas of southern China.
