六盘水东部一次连续暴雨天气过程分析

Analysis of a Continuous Rainstorm in the East of Liupanshui

摘要: 本文利用常规气象观测资料、地面自动气象站和FY2G卫星云图等资料对2015年6月六盘水市东部出现的暴雨天气过程进行了分析，结果表明：滇黔之间有南支槽活动，中高纬有高空槽东移，引导冷空气南下，由于副热带高压稳定，南支槽移动缓慢，地面辐合线发展，低层切变线和低空急流发展维持，为六盘水东部产生连续暴雨天气提供了充足的水汽和动力条件。

Abstract: Using the conventional meteorological observation data, ground automatic station data and FY2G satellite cloud images, etc., the continuous rainstorm in the east of Liupanshui in June 2015 is studied. The results showed that the south branch trough was active between Yunnan and Guizhou, and the high trough moved eastward in the middle and high latitudes, and the cold air was guided southward. Due to the stable subtropical high, the south branch trough moved slowly, the ground convergence line developed, the low-level shear line and the low-level jet developed and maintained, providing sufficient moisture and dynamic conditions for continuous rainstorm in the east of Liupanshui.
