2007年7月云南洪涝灾害天气原因分析
Analysis of Flood Disaster Weather in Yunnan in July 2007
摘要
Abstract
Based on the data of NCAR/NCEP reanalysis and the daily precipitation data of 124 stations in Yunnan Province,the effects of the southwest monsoon in the Bay of Bengal on precipitation in Yunnan were analyzed.Taking the whole heavy rain process in Yunnan province from July 18 to 20,2007,this process caused the more serious flood disaster in Yunnan.This paper studies and analyzes the weather causes of the flood disaster and finds that the establishment of the southwest water vapor channel before the monsoon trough in the Bay of Bengal contributes to the process of large precipitation in Yunnan.The transmission of the monsoon in the tropics to the north is the result.In July 2007,there was an important factor in the process of precipitation.Floods are usually small scale,and the weather process shows that the weather in some areas often has a large scale weather background.关键词
