中文摘要: 采用统计方法和数值模拟方法探讨人工影响后降水再分配和对局地降雨影响的可能性。统计结果表明:人工降雨影响了降水的自然分布,在作业点下风方出现了二个影响区:一个是增雨区(出现在作业点下风方15～50km ),另一个是减雨区(出现在作业点下风方90～150km )。数值模拟结果表明:人工催化影响降水演变过程,而且改变了降水的分布。通过人为有意识的影响,有可能达到调控降水,减弱局地降雨的目的。

Abstract:Using the statistical method and the numerical simulation method,the precipitation redistribution after weather modification and the possibility of the influence on local precipitation was discussed.Statistical results indicate that artificial rainfall influences the nature distribution of precipitation,and two pieces of influence area are appeared at downwind area of the operation base.One is a rain increasing area (at downwind 15—50km area of operation base), another is a rain reducing area(at downwind 90—150km area of operation base). Results of numerical simulation indicate that the artificial catalys influences the precipitation development procedure and transforms the precipitation distribution.It is possible to control precipitation and to weaken local precipitation through artificial conscious influence.
