摘要:
通过对2014年7月08-09日广西东南地区强降雨天气过程分析,得出此次过程的主要影响系统为:中层东风波、季风槽前低层西南暖湿气流。此次东风波系统主要是受西太平洋副高和大陆副高之间的切变发展而成,东风波槽前和波轴上利于上升运动的出现,为强降雨提供了有利的动力条件。季风槽前低层西南气流为强降雨提供了充沛的水汽。
Abstract:
Based on the analysis on the heavy rain occurred in the southeast of Guangxi on 8th-9th, July, 2014, it is found that the main affecting systems for this process are the mid-level easterly waves and southwest warm moist air before the low-level monsoon trough. This easterly waves is mainly affected by the shear by the western Pacific subtropical high and the mainland subtropical high. There is divergence between the wave axis and the front of easterly waves trough, which benefits to the heavy rain. The convergence of the low-level southwest air bring the adequate vapor for heavy rain.
