In order to better carry out the monitoring and early warning of hail weather in Jiangxi Province, using MICAPS data, automatic weather station data, radar mosaic data, radar PUP product data, dual-Doppler radar retrieved wind field data, hail disaster photos and videos, and WeChat hail information feedback, as well as principles and methods such as meteorology and radar meteorology, this paper analyzes the characteristics of the hail echoes in Jiangxi and surrounding regions on 14 March 2022. The results show that hails occurred in many places in Jiangxi and surrounding regions, with strong winds of ≥17.2 m·s-1 occurring at 20 regional stations, precipitation ≥50.0 mm occurring at 24 regional stations, and the mixture of thunderstorm gales and cold air. The main impact systems of the hail weather were the 200 hPa outflow zone, the 500 hPa south branch trough and wind speed shear, the 850 hPa low vortex and shear line, the surface convergence line, and the southwest inverted trough. After the correction the larger CAPE value, the stronger inversion layer, the mid-level dry region, and the lower-level wet zone provided ambient conditions for the occurrence of hail weather in Nanchang. Hailstones are mainly composed of supercell echoes, which were sometimes isolated, and sometimes in echo groups and bands. Echo intensity was ≥60 dBz. The minimum strong echo area was ≥18 km2, and the maximum ≥180 km2. The strong echo gradient at a distance of 30-60 dBz was ≤6 km, with obvious cloud anvil forward echo. The life spans of hail echoes were mostly more than 2 hours. In hail echo identification, the vertically integrated liquid (VIL) was a very important feature. The VIL of a single radar of Jiangxi hail was between 35-60 kg·m-2, and the VIL on the radar mosaic was 35-50 kg·m-2. On the CAPPI map of 2.5 km of hail echo, the hail echo intensity was ≥60 dBz, with a maximum of 65 dBz. Most echo centers of dual Doppler radar retrieved wind field had the characteristics of medium vortex structure, lateral convergence wind field, and convergence of north south wind field. Some individual wind fields were relatively messy. The above analysis results could provide an analytical basis for monitoring and early warning of hail weather in Jiangxi.
