台州市黄岩区人工增雨有利天气条件分析

Analysis of Favorable Weather Conditions for Artificial Precipitation Enhancement in Huangyan District,Taizhou City

在全球气候异常的背景下,部分地区频繁发生长时间干旱的问题,严重影响人们正常生活和工农业生产,而人工增雨是缓解这一状况的有效手段。本文利用浙江省区域自动站加密资料、NCEP GDAS/FNL提供的1×1和0.25×0.25逐6 h再分析资料和葵花8号卫星数据,对黄岩区2018-2019年26次人工增雨作业过程的天气条件进行分析。结果表明,黄岩区年内降水分布极不均匀,人工增雨作业主要集中在冬春两季;积雨云是黄岩区比较适宜作业的降水云型。

In the context of global climate abnormalities,prolonged droughts frequently occur in some area,which seriously affects people's normal life and industrial and agricultural production,and artificial precipitation is an effective means to alleviate this situation.This paper uses the encrypted data of Zhejiang regional automatic station,the 6-hour re-analysis data of 1×1 and 0.25×0.25 provided by NCEP GDAS/FNL,and the data of the Sunflower 8 satellite,so as to analyze the weather conditions during the 26 artificial precipitation enhancement operations in Huangyan District from 2018 to 2019.The results show that the distribution of precipitation in Huangyan District during the year is extremely uneven,and artificial precipitation enhancement operations are mainly concentrated in winter and spring;cumulonimbus cloud is a suitable precipitation cloud type in Huangyan District.
