“13·6·30”遂宁市特大暴雨成因的初探
Primary Study of the Extreme Rainfall Event in Suining City on 30 June 2013
摘要
Abstract
Based on the rain gauge data from automatic weather stations,conventional observations and NCEP analysis data,the extreme rainstorm that hit Suining City from 30 June to 2 July 2013 and the rela-tionship between the extreme rainstorm and the LLJ evolution are studied primarily.This extrem event was caused by the coupling interaction between plateau and southwest vortexes.The results show that the high-level vortex development is strengthened when the coupling interaction occurs between plateau and southwest vortexes,stimulating the generation of rainstorms in Suining City.Jet stream provides unstable energy for the development of high-level vortex.Ultra-low-level jet and low-level jet cannot cause a strong rainfall immediately,and sometimes severe rainfall process may occur two hours later.The degree of in-crease in the low-level jet index (I)and the intensity of rainfall have a direct proportional relationship.关键词
