摘要
用不同统计单元统计分析了河南省瓦权县1991-1992年高地作业的增雨效果。以田雨量为统计单元,33个作业日中76%(25天)显著地增加了雨量,2年共增雨329.lmm。以月、季为统计单元,作业期间增雨显著的为48%以上,而增雨效果不显著或雨量减少的为21%以下。但总的看,以年雨量为统计单元,民权县的人工增雨作业年均增雨14%,两年共增雨172.Zmm。
Precipitation enhancement experiment was carried out in Minquan County,Henan Province in two years (1991-1992). The antiaircraft guns firing 37mm AgI shells were used to seed the clouds. The seeded rainfall amount consisted of 48 per cent for a year, 71 per cent for summer and 99 per cent for July. The historical rainfall data of the experimental and contral area in 28 years were used to analyse the seeding effect. It was shown that rainfall was increased by seeding for 14per cent (172. 2mm) for a year. 31 per cent (188. 4mm) for sumrner and 45 per cent (103. 8mm) for July.
