摘要:
利用地面、高空气象观测资料、欧洲中期天气预报中心(ECWMF)0.25°×0.25°模式、风云气象卫星(FY-4)遥感信息、双偏振多普勒天气雷达探测数据等资料,对2023年6月7-10日北海暴雨过程的极端性特征与成因进行分析。结果表明:(1)此次暴雨过程由两个阶段的短时强降水组成,具有阶段性雨强大、过程积雨量大、强降雨集中等显著极端性特征。(2)高层辐散、中层副高位于两广交界、低层偏南急流强、季风低压停滞少动及地面弱冷空气入侵是极端暴雨形成的主要天气系统。(3)极端暴雨主要是由中尺度对流系统造成,云团稳定少动,对应的雷达回波为层积混合型降水回波,"列车效应"和低质心强回波长时间维持是造成极端降雨的直接原因。(4)风廓线VWP产品超低空急流的形成对强降水有一定的指示作用。
Abstract:
The extreme characteristics and causes of the rainstorm in Beihai during June 7-10, 2023 are analyzed by using MICAPS ground and high-altitude conventional meteorological observation data, ECWMF model data with 0.25°×0.25° resolution, FY-4 satellite data, dual polarization Doppler weather radar detection. The results show that:(1)The rainstorm is dominated by sustained short-term heavy rainfall, with significant extreme characteristics in terms of strong rainfall, large accumulated rainfall, and long duration of heavy rainfall.(2)The main weather systems responsible for the formation of the extreme rainstorm are the upper-level divergence, the mid-level subtropical high located at the junction of Guangdong and Guangxi, the strong low-level southerly jet, the stagnant monsoon depression and the invasion of weak cold air on the ground.(3)The extreme rainstorm is mainly caused by the mesoscale convective system. The cloud cluster is stable and less dynamic, and the corresponding radar echoes are the stratocumulus-mixed precipitation echoes. The "train effect" and the long-term maintenance of the low centroid strong echo are the direct causes of extreme rainfall.(4)The formation of the ultra-low-altitude jet stream on the wind profile VWP product is indicative of heavy precipitation.
