风暴相对螺旋度与强对流天气类型的关系分析
Relationship between storm relative helicity and types of strong convective weather
摘要
Abstract
The definition of storm relative helicity (SRH) was introduced.27 strong convective weather events from 2007 to 2008 were analyzed in Shijiazhuang, Hebei province.The characteristics of SRH in high and low levels were summarized in any combination ways of short time heavy rain, hailstone and gale weather.The results indicate that SRH value in low level is often positive but small under short time heavy rain weather condition.The SRH in high level is mainly positive as well.The difference of SRH between in high and low levels will increase rapidly under hailstone or gale weather condition.The maximum of SRH in high level exceeds 100 m2 ·s-2关键词
