摘要
本文应用常规观测资料、自动站加密观测资料、雷达资料及欧洲中心和T639数值预报产品,对2017年6月23—24日龙口市出现的暴雨天气的天气系统和触发机制进行了分析。结果表明,在华北冷涡与地面倒槽有利的高低空配置下,850 hPa暖式切变线以及低空低涡触发对流产生较强降水。
In this paper,the conventional observation data,automatic station encrypted observation data,radar data and European Center and T639 numerical forecast products were used to analyze the weather system and trigger mechanism of the heavy rain weather in Longkou City from June 23 to 24,2017. The results showed that, under the favorable high and low altitude configuration of the cold vortex and the ground trough in North China, the 850 hPa warm shear line and the low-altitude low vortex trigger convection produced strong precipitation.
