摘要:
利用常规气象资料及风廓线雷达资料分析2018年7月7日南宁吴圩国际机场一次强降水天气过程特征。结果表明此次强降水受中低层切变线南压、西南季风槽北抬及地面冷空气渗透共同影响，强降水发生前地面及空中风场变化特征明显。风廓线雷达资料中功率谱密度、垂直速度、最大探测高度与降水强度关系密切，垂直速度及探测高度的变化对降水临近预报有一定指示意义，低空风切变对本场航空器起落产生了重要影响。
Abstract:
Using conventional meteorological data and wind profiler radar data, the characteristics of a heavy rainfall process at Nanning Wuxu International Airport on July 7, 2018 were analyzed. The results show that the heavy precipitation is affected by the southward moving of the shear line at the middle and lower layers, the northward uplift of the southwest monsoon trough and the surface cold air infiltration. The variation characteristics of the surface and air wind fields are obvious before the heavy precipitation occurs. The power spectral density, vertical velocity and maximum detection altitude of wind profiler radar data are closely related to precipitation intensity. The variations of vertical velocity and detection altitude have a certain guiding significance for precipitation proximity prediction. Lowaltitude wind shear has an important impact on aircraft taking off and landing.
