Abstract According to the conventional weather data of MICAPS,hourly ground automatic station observation data,FY2E satellite TBB data,Jiangxi WebGIS radar mosaic data,Jingdezhen Doppler radar and wind profiler radar data,this paper analyzes the local short-term heavy precipitation process in Jingdezhen on July 4,2019.The large-scale circulation background,stratification and environmental conditions are analyzed in detail.In terms of the characteristics of short-time heavy precipitation,this paper analyzes the characteristics of radar mosaic echo,Jingdezhen SA radar product and satellite cloud images.The analysis results provide a basis for understanding the influence of ground convergence line on short-time heavy precipitation.
