辽宁省抚顺市2016年6月一次暴雨过程分析

Analysis on a Rainstorm Process of Fushun in June 2016

利用常规、加密自动气象站以及NCEP/NCAR再分析等资料,分析了2016年6月10—11日抚顺一次暴雨过程的天气尺度系统。结果表明,此次过程以对流性降水为主,具有短时强降水特点,并伴有雷暴、大风等灾害性天气,同时雨量分布不均,南部雨量整体偏大。东北冷涡是此次降水的主要影响系统,与地面华北气旋对应位置配合较好,低空急流提供了较好的水汽输送,850 h Pa切变线提供了较强的辐合上升运动。

A synoptic scale of rain- storm process in Fushun in 10-11th, June 2016 was analyzed,hy using re- analysis data of conventional and en- cryptiml AWS,as well as NCEP/NCAR, etc. The results showed that the main of this process was convective preeipitation .and had feature of heavy rainfall,a,ul accompanied with severe weathers,such as thunde^tonns, high winds,etc. At the same time,rainfall was uneven distribu- tion,and rainfall in southern overall was larger. Northeast cold vortex was main impact of the precipitation system. It was coordinate better with the eorre- sponding position of ground in North cyclone. LLJ provided hetter water vapor transport,and 850 hPa shear line provid- ed strong eonvergenee ascending motion.
