Abstract In order to master the echo classification and characteristics of short-term heavy precipitation in Wuyuan,this paper analyzes the radar echo characteristics of 17 short-term heavy precipitations in Wuyuan from 2015 to 2020 by using Jiangxi WebGIS radar mosaic data and meteorological observation data of Wuyuan national station and adopting elementary analysis,data statistics,image contrast and other analysis methods.This paper introduces the data source and the general situation of short-term heavy precipitation in detail.And the characteristics of the radar mosaic echo system of short-time heavy rainfall affecting Wuyuan are analyzed,including flocculent echo band,short echo band,single echo band and thunderstorm echo band.At the same time,the rainfall in Wuyuan is analyzed,which laid a foundation for the early warning and forecast of short-term heavy precipitation weather and meteorological service in Wuyuan.
