Abstract：Based on sounding,reanalysis,surface observation,ADTD lightning location,and lightning disaster data from Chuzhou City between 2011 and 2021,this study analyzes the atmospheric circulation and lightning parameter characteristics of 14 disastercausing thunderstorm processes.The results indicate that these events primarily occur from June to August and are mainly influenced by six circulation patterns,with the upperlevel cold vortex type being the most frequent.Thermodynamically,these processes are generally characterized by high CAPE,predominantly negative LI and SI values,high K indices and T850500 temperature differences,and moderate or greater vertical wind shear.Spatially,the lightning strike density in Chuzhou exhibits a "high in the central and eastern regions,low in the western regions"pattern,with southeastern Tianchang,southern Lai'an,centraleastern Mingguang,and parts of southern Quanjiao identified as highfrequency areas.Furthermore,the cloudtoground lightning intensity ranges from 0.5 to 0.71,with highvalue centers located in Tianchang,Lai'an,Langya,Nanqiao and Quanjiao.
