青海省贵南地区一次局地短时强降水天气过程分析

摘要

A local short-term strong precipitation occurred from 23:00, 6 July 2014 to 00:00, 7 July 2014 in Guinan Area of Qinghai Province was analyzed in the aspects, such as circulation situa-tion, synoptic system, physical quantity fields, satellite image, mesoscale charac-teristics, and terrain. The results showed that the short-term strong precipitation in Guinan was due to the short wave trough split off from trough bottom of Balkhash Lake. The high temperature and high hu-midity in earlier stage provided enough water vapor and energy conditions for the strong precipitation. Based on the analy-sis above, the forming cause of the pre-cipitation was concluded.%2014年7月6日23：00至7日00：00青海省海南州贵南地区出现了局地的短时强降水天气，从环流形势、影响天气系统、物理量场、卫星云图、中尺度、地形等方面对其进行了分析。结果表明，巴尔喀什湖槽底分裂的短波槽是导致贵南地区出现短时强降水的主要原因。前期高温高湿，为强降水提供了充足的水汽和能量条件。并在综合分析的基础上，得出了此次强降水的形成原因。
