Abstract  Using MICAPS routine weather map data,satellite cloud image data,Jiangxi WebGIS radar mosaic data and single station SA radar data from 2016 to 2019,this paper analyzes the strong weather at the edge of subtropical high in Jiangxi by statistical methods,morphological analysis and comparative analysis.The results show that there are two types of subtropical high edge,which are convergence at the edge of subtropical high and the low trough at the edge of the subtropical high.At the same time,the features of the WebGIS radar jigsaw echo and the product features of the single station radar as well as the two ways of thunderstorm movement at the periphery of subtropical high are described.
