摘　　要：利用地面自动气象站、双偏振多普勒天气雷达等观测资料,对2022年7月17日务川县一次火箭增雨作业效果进行统计检验和物理检验。通过对影响区和对比区作业前后雨量及雷达参量的演变差异,完整分析此次人工增雨作业的催化效果。结果表明,此次增雨效果显著,区域对比分析通过0.1的显著性检验,绝对增雨量为12.1 mm,相对增雨率为30.3%,总雨量增值达774400 m3;催化效果在作业后15 min起到效果,影响区强回波迅速生成发展,并在1 h左右贝吉龙效应达到最强,强回波区面积、液态水含量跃升变率及高值区占比、冰粒子尺度和数量等参量均大于对比区,人工增雨催化作用能够被观测的物理效应所证实,为务川县人工增雨保障气象服务的顺利开展积累经验。Based on the observation data of ground automatic weather station and dual polarization Doppler weather radar,statistical and physical tests were carried out on a rocket rain enhancement operation in Wuchuan County on July 17,2022.Through the evolution differences of rainfall and radar parameters before and after the operation in the affected area and the control area,the catalytic effect of this artificial precipitation enhancement operation is analyzed completely.The results show that the effect of rain enhancement is remarkable.The regional contrast analysis has passed the significance test of 0.1.The absolute rainfall increase is 12.1 mm,the relative rainfall increase rate is 30.3%,and the total rainfall increment reaches 774400m3.The catalytic effect was effective in 15 min after operation,and the strong echo in the affected zone was generated and developed rapidly,and the Bergeron Effect reached the strongest in about 1 hour.The strong echo area,the jump rate of liquid water content and the proportion of high value region,the size and quantity of ice particles and other parameters were larger than those in the control area.The catalysis of artificial precipitation enhancement can be confirmed by the observed physical effects,which accumulates experience for the smooth development of meteorological services in wuchuan county.
