摘　　要：为了进一步分析雷暴回波带与雷暴及闪电活动的关系,文章使用雷达拼图资料和闪电资料,对2024-04-02湖南、江西、浙江一带的多条雷暴回波短带及其闪电特征进行分析。结果表明:多条雷暴回波带发生在冷空气南下和西南倒槽中,东北西南走向辐合线上,短带回波最大强度达到65~70 dBZ;1 h雷电分布在湖南、江西、浙江一带,雷电分布带位置与雷暴回波带位置一致;雷暴聚类团移到建德上空,建德出现较密集的雷电天气。密切监视雷暴回波短带的移动有利于把握雷电的活动规律。In order to further analyze the relationship between thunderstorm echo bands and thunderstorm and lightning activity,this article uses radar mosaic data and lightning data to analyze multiple thunderstorm echo short bands and their lightning characteristics in Hunan,Jiangxi and Zhejiang on April 2,2024.The results showed that multiple thunderstorm echo bands occurred in the cold air southward and southwest trough,along the northeast southwest convergence line,with the maximum intensity of short band echoes reaching 60 dBZ to 70 dBZ.1 hour lightning is distributed in Hunan,Jiangxi and Zhejiang,and the location of the lightning distribution zone is consistent with the location of the thunderstorm echo zone.The thunderstorm cluster moved to the airspace over Jiande,and Jiande experienced more intense thunderstorm weather.Closely monitoring the movement of short bands in thunderstorm echoes is beneficial for understanding the activity patterns of lightning.
