摘要
采用相关区域降水数据以及同期相关气象观测资料,利用统计检验和线性拟合的方法,对平远2018年5月7日16:30人工增雨的作业条件和作业后的效果评估进行了相关分析。结果表明:作业时,天气形势和雷达实况资料均符合作业条件。作业前,平远人工增雨作业区域与选定的对比区降雨呈显著正相关;利用两者实测降雨量与拟合值对比分析可知,作业后15～45 min内的平均增雨率达到41. 5%。因而,降雨云团经过人工增雨火箭的催化影响,人工增雨作业的影响区域降雨量依次出现明显增大趋势,此次作业时机选择合适,作业效果明显。
Based on the related area precipitation data and the corresponding meteorological observation data in this paper,and the statistical test and linear fitting method are used to analyze the operation conditions and the effect evaluation after the operation at 16 :30 in Pingyuan in May 7,2018. The results show that weather conditions and radar data are in line with working conditions during operation. Before the operation,the rainfall in Pingyuan was significantly positive correlation with the selected contrast area,and the average rainfall rate in 15-45min after the operation was 41.5%. As a result,the precipitation clouds are affected by the catalysis of artificial precipitation rocket,and the rainfall in the area affected by the weather operation is obviously increasing in turn. The operation time is suitable and the operation effect is obvious.
