摘　　要：对2002-2003年7-9月间夏季对流云降水观测取得的36个对流云降水单体资料,利用数理方法进行了计算、处理和分析,结果表明:合并对流云降水单体液态含水量,比强对流云降水单体液态含水量偏少269.76×106m3,偏少48.45%;比普通对流云降水单体液态含水量偏多198.68×106m3,偏多2.25倍;强对流云降水单体降水效率最大,为25.74%,比普通对流云降水单体偏多15.74%,比合并对流云降水单体偏多13.21%。By use of mathenmtic statistics, the 36 convective cloud precipitation single observations oblained in summer, from July to September, during 2002 - 2003 were calculated and analyzed. The result shows that the single liquid state water content of merge convective cloud precipitation is 269.76 × 10^6 m^3 less than that of strong convective cloud precipitation and 198.68 × 10^6 m^3 more than that of ordinary convective cloud precipitation. The single precipitation efficiency of the strong convective cloud precipitation is the highest and reaches to 25.74% which is 15.74% more than that of ordinary convective cloud precipitation and 13.21% more than that of merge convective cloud precipitalion.
