江西饶河流域大暴雨短时强降水特征分析
Analysis on the Characteristics of Short-term Heavy Rainfall in Raohe River Basin,Jiangxi Province
摘要
Abstract
In order to do a good job in the short-term and imminent forecast of heavy rainstorm in Raohe River Basin,Jiangxi province,the data of heavy rainstorm in Raohe River Basin(Le'an River in the south branch)from 2013 to 2022,weather maps,radar echoes and other data were used to study the heavy rainstorm weather in Raohe River Basin by using the principles and methods of statistics,synoptic science,radar meteorology and so on.The main conclusions are as follows:1)The number of heavy rainstorm in Raohe River Basin increases year by year,and the short-term heavy rain and heavy rainstorm are normally distributed in June.2)Short-term heavy rainfall is mostly caused by band echoes,manifested as flocculent echo short bands,flocculent echo bands,echo bands,and echo short bands.3)Low trough,shear,jet stream,subtropical high and other weather systems are the main weather systems of heavy rainstorm in Raohe River Basin.4)The floc-culent echo cluster(band)structure is relatively loose,and the echo short band structure is dense.When the echo system merges,the echo strengthens and develops,which may lead to extreme pre-cipitation.These results provide a reference for the forecast and early warning of heavy rainstorm in Raohe River Basin,Jiangxi province.关键词
