摘要:
利用区域自动站资料、常规高空资料、地面观测资料、雷达和云图，对2019年5月27-28日发生在广西西部的一次特大暴雨过程进行诊断分析。结果表明，在暴雨期间有切变和地面弱冷空气影响广西；边界层到对流层中层风速小，导致中尺度对流系统发展之后移动缓慢；温度平流是上升运动的主要贡献者；暴雨发生前广西的西部到南部湿层深厚，垂直风切变小，暖云厚度厚，有利于大暴雨和特大暴雨的产生；云团长时间的维持造成了大范围的强降水；列车效应是造成强降水的直接原因。
Abstract:
Based on the data of regional automatic station, conventional high altitude data, ground observation data, radar data and satellite cloud image, an extraordinary rainstorm that occurred in western Guangxi from May 27-28, 2019 was analyzed. The results showed that there were shear and weak cold air on the ground during the rainstorm. The low wind speed from the boundary layer to the middle troposphere led to the slow movement of the mesoscale convective system. The analysis of uplift conditions showed that the temperature advection was the main contributor to the uplift. During the process, there were obvious unstable energy accumulation and water vapor convergence conditions in the lower layer of Guangxi. From the radiosonde analysis of environmental conditions, the wet layer was deep from the west to the south of Guangxi before the rainstorm, the vertical wind shear was small, and the warm cloud thickness was thick, which was conducive to the occurrence of heavy rainstorm and extraordinary rainstorm. The maintenance of cloud duration resulted in the large-scale heavy precipitation. The train effect is the direct cause of heavy rainfall.
