摘要:
利用常规观测资料、广西自动站雨量资料以及雷达探测资料等,对2015年5月18~20日桂东北一次典型暴雨过程进行分析。结果表明:(1)高空槽东移、低层低涡切变和地面冷空气南下是此次强降水过程的主要影响系统。(2)桂东北较为深厚的湿层和弱风切的局地环境,适当的不稳定条件等,提供了重要的上干下湿的层结条件。(3)桂东北北高南低的迎风坡地形也是引发此次暴雨的另一个因素,气流的有效辐合更是有利于强降水的发生。
Abstract:
Based on the conventional observation, rainfall data of regional automatic station and Radar data, a typical rainstorm process on 18 to 20 May 2015 in northeast of Guangxi was analyzed. The results show:(1) moving eastward of upper trough, the low-level vortex shear and invading southward of cold air made up the main effective system of this heavy rain process; (2) relatively deep wet layer, weak wind shear and appropriate unstable conditions in northeast of Guangxi provide an important stacking conditions that is upper-dry -and-low-wet. (3) The north-high-and-south-low terrain of windward slope is another reason that led to this rainstorm, effective convergence of airflow is conducive to the occurrence of heavy rain.
