Analysis of the Effect of an Artificial Precipitation Enhancement Operation on Improving Air Quality

摘要: 本文使用空气环境质量数据、地面降水资料，对2019年12月25日一次人工增雨作业改善空气质量进行了效果分析，结果表明：增雨作业初期受吸湿增长与输入污染物影响，PM2.5与PM10出现先上升后下降特点，后期随着降雨量加大，时间增加，降水湿清除作用明显，PM2.5与PM10下降趋势明显，其中PM10的下降速度明显优于PM2.5下降，空气质量由中度污染转为优良，增雨作业对改善空气质量效果明显。

Abstract: Base on air environmental quality data and surface precipitation data, this paper analyzes the effect of an artificial precipitation enhancement operation on December 25, 2019 to improve air quality. The results show that: Affected by moisture absorption and input pollutants, PM2.5 and PM10 rise first and then fall. In the later period, with the increase of rainfall and the increase of time, the wet removal effect of precipitation was obvious, and the decrease rate of PM10 was obviously better than that of PM2.5, and the air quality turned from moderate pollution to good. The precipitation enhancement operation has obvious effect on improving air quality.
