摘　　要：为了有效监测预警铜鼓雷暴大风天气,使用铜鼓国家站气象数据、江西WebGIS雷达拼图等数据,采用雷达气象学原理及分析方法,对铜鼓6次雷暴大风回波特征进行分析。结果表明:铜鼓地区2013—2024年出现6次雷暴大风(风速≥17.2 m/s);这些强天气多伴有500 hPa低槽、850 hPa切变和西南急流及925 hPa超低空急流等天气系统;铜鼓地区雷暴大风有多单体、飑线回波带(台风外围飑线)、超级单体和复合单体四种回波类型。研究结果为监测预警铜鼓地区雷暴大风天气提供了分析依据。In order to effectively monitor and warn of thunderstorms and strong winds in Tonggu,meteorological data from Tonggu National Station and data from Jiangxi WebGIS radar mosaic were used to analyze the echo characteristics of six thunderstorms and strong winds in Tonggu using radar meteorology principles and analysis methods.The results indicate that there were 6 thunderstorm gusts(wind speeds≥17.2 m/s)in the Tonggu area from 2013 to 2024.These strong weather events are often accompanied by weather systems such as 500 hPa trough,850 hPa shear,southwest jet stream,and 925 hPa ultra low altitude jet stream.Thunderstorms and strong winds in Tonggu area can be classified into four types of echoes:multiple cells,squall line echo bands(peripheral squall lines of typhoons),super cells,and composite cells.The research results provide an analytical basis for monitoring and warning thunderstorm and strong wind weather in Tonggu area.
