There are 15 cases of thunderstorm and gale processes in Yushan County from 2004 to 2020 are analyzed through various analysis methods based on MICAPS weather map, Jiangxi WebGIS radar puzzle, Jiangxi automatic weather station and Shangrao SA Radar data. The results show that the thunderstorm and gale in Yushan is mainly concentrated from May to September, of which the peak is in July. Thunderstorm and gale have obvious diurnal variation, and the afternoon is a period with high-occurrence due to the warming. There are three types of mesoscale systems in Yushan thunderstorm and gale weather:the cold front and inverted trough type, the subtropical high control type and the tropical system type. The Radar Mosaic echo features can be divided into three categories:the supercell on squall line echo belt, the strong cell on squall line (bow) echo belt and the strong echo short belt on the edge of subtropical high and strong echo of local geothermal thunderstorm. The echo intensity of the supercell center on the squall line echo belt is larger than 60 dBZ, and the echo has an obvious "bow" structure, and the moving speed can reach 80-100 km·h^-1. The thunderstorm and gale weather at the edge of the subtropical high occurs when the echo of local geothermal thunderstorm intensity develops and merges, with strong locality and slow movement, and the moving speed is only about 30 km·h^-1. The main differences between supercell hail and thunderstorm gale on radar PUP products are as follows:60 dBZ strong echo area of combined reflectivity CR products is large, hail is large but thunderstorm gale is small; Vertical accumulated liquid water hail can reach 60 km·h^-1, and thunderstorm gale VIL ≤ 35 km·h^-1; Reflectivity factor vertical profile Reflectivity Cross Section (RCS) hail has greater than 65 dBZ strong echo core, but thunderstorm and gale do not; Mesocyclone structure appears in Velocity Cross Section (VCS) hail in radial velocity vertical profile, and the thunderstorm gale appears "upwind area" or weak shear structure.
