2022年一次果洛北部暴雨天气过程分析

Analysis of a Rainstorm Weather Process in the North of Guoluo in 2022

对果洛州2022年6月24—25日发生的一次强对流天气进行分析,得出:西太平洋副高东退,西南气流携带暖湿气流与西风槽槽后冷空气交汇引发不稳定能量释放,明显辐合线长时间维持触发降水,同时深厚湿层以及低层辐合、高层辐散引发强烈的上升运动成为降水有利条件,卫星云图和雷达产品发展演变与降水落区、时间都有很好的对应性。

Based on the analysis of a strong convective weather that occurred in Guoluo state on June 24—25,2022,it was concluded that the West Pacific sub high retreated eastward,the southwest airflow carrying warm and humid air converged with the cold air behind the west wind trough and triggered the release of unstable energy,and the obvious convergence line maintained for a long time to trigger the precipitation.At the same time,the strong upward movement caused by the deep wet layer,low-level convergence and high-level divergence became the favorable conditions for precipitation,The development and evolution of satellite cloud images and radar products correspond well to the precipitation falling area and time.
