A Comprehensive Evaluation of the Effect of Artificial Precipitation in Gutian Reservior Area
-
摘要: 该文是对福建省古田水库地区12年（1975—1986年）人工降雨随机试验效果进行综合评价。统计分析表明244次随机试验得出20%（α＜0.05）左右增雨效果。各种观测分析（冰核、雨水中Ag+含量，雷达回波、雨滴谱）及数值模拟结果为人工增雨统计结论提供了初步的物理学解释。Abstract: Artificial experiments were performed in the Gutian reservoir region during April to June of 1975–1986. The statistical analyses from 244 experiments indicate that the effect of precipitation enhancement can reach about 20% by seeding. Meanwhile, the various cloud physics observations, including the concentration of ice nuclei, the Ag+ content in rain water, the features of radar echoes and the raindrop size distribution, and numerical simulations have been conducted. The results provide a preliminary physical explanation for the statistical conclusions
