山东无棣人工增雨效果的统计检验
Statistical test of effect of artificial rainfall enhancement in Wudi,Shandong
摘要
Abstract
To objectively evaluate the effect of artificial rainfall enhancement in Wudi,Shandong,based on the precipitation data of national basic meteorological stations and regional meteorological observing stations in Binzhou and Wudi between April and July from 1964 to 2023,three statistical test methods,namely sequence analysis,regional regression analysis and regional comparative analysis,are used to analyze the effect of artificial rainfall enhancement from 2014 to 2023.The results are listed as follows.(1)The 10-d average absolute rainfall increase obtained by sequence analysis/regional regression analysis is 7.24/7.89 mm between April and July;the sequence analysis passes the significance test at the level of 0.05 in April,May and July;the regional regression analysis passes the significance test at the level of 0.05 in April and July.(2)The regional comparative analysis shows that the daily average absolute rainfall increase is 3.75 mm and the average relative rainfall increase rate is 21.93%;it passes the significance test at the level of 0.05 in April,June and July,and the level of 0.10 in May.关键词
