摘　　要：利用常规探测资料、数值模式等多源资料对2022年3月14日景德镇一次强对流天气过程进行分析。分析表明:(1)此次过程是高空偏西北气流影响下多单体风暴造成的强对流天气过程,强对流灾害会有雷暴大风、冰雹等;(2)冷锋与水平对流卷在景德镇相遇,有利于雷暴加强和维持,雷暴高度组织化整齐排列,强回波(55 dBz)在景德镇稳定少动,回波走向与景德镇垂直,故造成了短时强降水的发生;(3)0~6 km垂直风切变只是一般参考值,0~8 km垂直风切变往往会更加具有风暴结构的指示意义;(4)此次过程在灾害出现10 min前已经出现了强对流天气指示因子,预报员需时刻保持警惕,提前做出预警。A severe convective weather process in Jingdezhen on March 14,2022 is analyzed by using conventional sounding data,numerical model and other multisource data.The analysis showed that:(1)This process was a severe convective weather process caused by multi cell storms under the influence of the upper northwest air current.It was analyzed that severe convective disasters may include thunderstorm,gale,hail,etc.(2)The cold front met the horizontal convection roll in Jingdezhen,which was conducive to the strengthening and maintenance of thunderstorms.The thunderstorms were highly organized and orderly arranged.The strong echo(55 dBz)was stable and less moving in Jingdezhen,and the echo trend was vertical to Jingdezhen,which caused shortterm heavy precipitation.(3)The 0~6 km vertical wind shear is only a general reference value,but the 0~8km vertical wind shear is often more indicative of the storm structure.(4)The indicated factors of severe convective weather process appeared 10 minutes before the disaster,forecasters need to always be vigilant,and make an early warning in advance.
