| 摘要: |
| 该文根据探空资料、宏观记录、FY2卫星反演资料、雷达资料等，利用多参量动态对比方法，经作业合理性分析、作业催化剂扩散分析、作业影响区的计算、作业对比区的选择4个步骤对2018年5月3日飞机人工增雨个例进行效果检验分析，得出：影响区雷达回波K值、地面小时雨量K值在作业后3h变化趋势均为先增后减，作业后有一定的效果，表明该效果检验方法适用于贵州飞机增雨效果检验。 |

| Abstract: |
| Based on radiosonde data, macro records, FY2 satellite data, radar data, etc., the effect of Aircraft Artificial Precipitation Enhancement on May 3, 2018 is analyzed by using multi-parameter dynamic contrast method. Four steps are included: rationality analysis of operation, analysis on operation catalyst diffusion, caculation of the operation-influenced area, and selection of operation comparison area, The results show that the change trend of radar echo K value in the influenced area and the K value of surface hourly rainfall increases first and then decreases after 3 hours of operation. The effect made after operation indicates that the effect test method is suitable for aircraft precipitation enhancement in Guizhou. |
