Based on rain drop size distribution ( dsd ) data measured in qingdao, guangzhou and xinxiang, the radar reflectivity factor z for spherical rain drops, the radar reflectivity factor zh and differential reflectivity zdr for oblate ellipsoid rain drops have been calculated. the relation of reflectivity and rainfall rate for conventional meteorological radar and the relation of reflectivity, differential reflectivity and rainfall rate for multiparameter radar are regressed, the performance difference of two kinds of radar for measuring rainfall and difference for measuring rainfall in different regions are also discussed
基於我國青島、廣州和新鄉地區雨滴尺寸分佈數據，計算了球形雨滴雷達反射因子，橢球形雨滴雷達水平極化反射因子和差分反射率，回歸給出了這些地區的常規氣象雷達反射因子與降雨率的經驗關系和多參數雷達水下極化雷達反射因子、差分反射率和降雨率關系，並對其測雨精度和地區差異進行了比較。
