Abstract The climatic characteristics of regional severe convection in Jiangxi Province were analyzed in this paper, and satellite cloud images above 20 stations of regional severe convection weather since 1998 were classified. The results show that the Jiangxi regional severe convection weather is mainly based on thunderstorm, heavy wind and strong precipitation with small possibility of the hail. And there are obvious diurnal variations of regional severe convection weather. The most occurrence districts are located in the central, eastern and western of Jiangxi Province. Cloud patterns of regional severe convection weather can be classified into the following 7 types: subtropical high edge, convection current at bottom of trough, cloud cluster developing, warming ahead of system, baroclinic cloud system moving, squall line, convection developing within low trough cloud. Among these types, the last type is the most.
