摘要:
利用多普勒雷达探测资料、地面常规资料和探空资料及自动站数据对2018年5月7日17时前后出现在来宾的强冰雹、雷雨大风、短时强降水等强对流天气进行详细分析。结果表明：上干下湿的不稳定的层结，配合切变线、东移的高空槽前等有利的大尺度环流背景，地面弱冷空气触发对流导致此次来宾市强冰雹天气的出现。多普勒雷达资料上具有超过65dBz的强回波、三体散射（TBSS）、旁瓣回波和有界弱回波区（BWER）、垂直累积液态含水量（VIL）跃增等特征。
Abstract:
Using the data of the Doppler radar, surface data, sounding data and automatic station data, heavy hail, thunderstorm, gale, and short-term heavy precipitation that occurred in Laibin on May 7, 2018 were analyzed in detail. The results show that the unstable stratification of upper dry and lower wet, combined with the favorable largescale circulation background such as shear line and eastward moving high-altitude trough, and triggered convection by weak cold air on the ground, led to the occurrence of severe hail weather in Laibin City. Doppler radar data have characteristics such as strong echo over 65dBz, three-body scattering (TBSS), side-lobe echo, bounded weak echo region (BWER), and vertical liquid water content (VIL) jump, etc.
