一次层状云火箭增雨作业效果分析
Effect Verification and Analysis for Artificial Precipitation Enhancement of Stratiform Cloud by Rocket in Dalian
摘要
Abstract
This paper focuses on the effect verification and analysis of artificial precipitation enhancement for a stratiform cloud precipitation event,which occurred over Dalian on 12 April 2015,by using statistical and physical verification methods.The results reveal that the relative rain enhancement rate increases by 49% (α<0.01)in 30-50 min after catalyzing the operational clouds and reaches the maximum rainfall rate by calculating the minutely rainfall of observational and fitted values in the operation and contrast area. Moreover,significant improvement exhibits in physical effects in terms of radar echo intensity and area of target cloud,precipitation duration and variation characteristics of raindrop spectra in fitting clouds.关键词
