Case Study on the Convective Clouds Seeding Effects in Yangtze-Huaihe Region
摘要
Abstract
Convective clouds in Yangtze-Huaihe Region are the main seeding objects of precipitation en-hancement experiments in Anhui Province in summer.Unrandomized seeding operations are usually adopt-ed using rocket launchers,artilleries or ground generators,rather than the randomized trials through strict test design due to some limited condition.Convective clouds have characteristics of short life span and con-siderable large local and natural variations,which add great difficulties to the objective,scientific and quantitative evaluation of the operation effects.Based on daily rainfall data of national ground stations of Anhui Province and SA Doppler Radar data of the operation areas,this paper makes a case study on the seeding effects of convective clouds in Yangtze-Huaihe Region from 28 to 30 June 2012 with combination of regional historical regression statistical analysis and physical test method using Doppler Radar identifica-tion and track of cloud seeding.The results indicate that the rainfall of target area increases 37.2 mm and obtains an enhancement rate of 65.19% after seeding,with a significant level α<0.1.We identify and track seeded units according to the radar data,define appropriate control units and then compare the radar echo parameters of seeded units and control units before and after operation to give physical evidence of the operation effects.关键词
