Abstract Using conventional weather data,automatic rainfall data,Jiangxi WebGIS radar jigsaw puzzle and other data,this paper analyzes the three heavy rain processes in Yingtan in 2019 by means of mathematical statistics,weather analysis and morphological comparison.The actual precipitation,distribution of three short-term heavy precipitation and weather background are introduced in detail.The evolution and characteristics of radar echo are analyzed in detail and the conclusion is drawn,which can provide scientific basis for early warning forecast of heavy rainstorm and meteorological service in Yingtan.
