摘　　要：为了提高对泰州地区暖季强对流天气的认识,利用2013—2022年常规地面和高空观测资料及地面区域自动站资料,筛选出泰州地区53次冷涡强对流天气过程,通过动态合成开展分析。结果表明:冷涡强对流主要有短时强降水、雷暴大风和混合型三种类型,其中混合型强对流发生频次最多(31次),最大小时雨强主要集中在20.0~29.9 mm/h和30.0~49.9 mm/h,雷暴大风风力在8~9级占比最多(44%);对流触发时间呈三峰型分布,主要集中在夜间、早晨和午后,最高峰为13:00—16:00。In order to improve the understanding of strong convective weather during the warm season in Taizhou area,53 cold vortex strong convective weather processes in Taizhou area were screened using conventional ground and high-altitude observation data from 2013 to 2022 and ground area automatic station data,and analyzed through dynamic synthesis.The results show that cold vortex strong convection mainly includes three types:short-term heavy precipitation,thunderstorm strong winds,and mixed type.Among them,mixed type strong convection has the highest frequency of occurrence(31 times),and the maximum hourly rainfall intensity is mainly concentrated in 20.0-29.9 mm/h and 30.049.9 mm/h.Thunderstorm strong winds account for the highest proportion(44%)at 89 levels;The triggering time of convection exhibits a three peak distribution,mainly concentrated at night,morning,and afternoon,with the highest peak occurring from 13:00 to 16:00.
