摘　　要：2005年6月27日甘肃永昌实施了火箭人工增雨作业,XDR数字化天气雷达对这次增雨过程进行了跟踪探测。通过分析这次人工增雨前后天气学背景和雷达回波演变情况,证明在有利的天气形势下,通过火箭人工增雨作业后,雷达回波强度增强、回波范围和地面降水频率增大,作业后24 h地面雨量的分布情况也佐证了这一结果。On June 27th, 2005, the rocket rainfall enhancement operation was undertaken in Yongchang county of Gansu province, and the process was tracked and monitored by XDR digital weather radar. Through the analysis of synoptic background and radar echoes evolution before and after the rainfall enhancement operation, it was proved that under the favorable weather condition, after the rocket rainfall enhancement operation, the intensity of radar echo was increasing, the scope of radar echoes and the frequency of surface precipitation were enlarging, and the distribution of surface precipitation in 24 hours after the operation also confirmed the effect of this rocket artificial influence on rainfall.
