摘　　要：根据2019年5月26日朝阳1次人工增雨作业,通过分析天气形势、增雨潜力、雷达资料等重点研究了此次飞机人工增雨过程。结果表明,5月26日受江淮气旋北上和高空槽东移共同影响,充沛的水汽输送,水汽、动力条件较好,朝阳地区有降水过程。作业云系过冷水含量丰富,冰晶数浓度较小,增雨潜力较强,适合开展增雨作业。飞机人工增雨作业结束后雷达回波强度明显增强,回波范围扩大,增雨效果显著。According to an artificial rain enhancement operation in Chaoyang on May 26,2019,the process of aircraft artificial rain enhancement was studied by analyzing weather situation,rain enhancement potential and radar data. The results showed that on May 26,affected by the northward movement of the Jianghuai cyclone and the eastward movement of the high trough,there was abundant water vapor transport,good water vapor and dynamic conditions,which resulted in the precipitation process in Chaoyang area. The content of supercooled water in cloud system was rich,the concentration of ice crystal number was small,and the potential of increasing rainfall was strong,so it was suitable for increasing rainfall. The radar echo intensity was obviously enhanced,the echo range was expanded,and the effect of rain enhancement was significant after the aircraft artificial rain enhancement.
