摘　　要：本文利用常规气象观测资料、NCEP分析资料以及雷达探测资料对2019年4月18-19日福建地区一次强对流天气过程进行分析。结果表明:此次强对流天气期间,500hPa槽前西南急流对闽中一带产生影响,偏西急流对福建南部一带造成影响,导致这些地区出现强降水、大风天气过程。在本次大风、降雨等强对流天气出现过程中,福建南部具备强水汽输送通道,并且比湿值处于12.0g/kg至14.0g/kg之间,这些均为短时强降水天气的发生带来了丰富的水汽资源。This paper analyzes a severe convective weather process in Fujian Province from April 18 to 19,2019,using conventional meteorological observation data,NCEP analysis data,and radar detection data.The results indicate that during this period of severe convective weather,the southwest jet stream in front of the 500hPa trough affected the central Fujian region,while the westward jet stream affected the southern Fujian region,leading to heavy precipitation and strong wind weather in these areas.During the occurrence of strong convective weather such as strong winds and rainfall,the southern part of Fujian had a strong water vapor transport channel,and the specific humidity value was between 12.0g/kg and 14.0g/kg,which provided abundant water vapor resources for the occurrence of short-term heavy rainfall weather.
