摘要
利用2016年5月2—4日的NCEP/NCAR逐日再分析资料对发生在辽宁地区的一次黄淮气旋爆发性降雨过程进行了研究分析,分析表明:此次降水过程黄淮气旋在东移过程中与高空冷涡相配合,形成深厚的辐合系统,继而产生大范围的强降水天气,西南暖湿低空急流不仅为暴雨的产生提供了水汽输送条件,而且为暴雨、大风的产生提供了动力条件。此次黄淮气旋暴雨期间能量的水平输送及垂直交换有利于对流的发展,有利于降雨及大风的维持和加强。
Based on NCEP/NCAR daily reanalysis data during May 2 to 4,2016,a rainfall process caused by explosive Huanghuai cyclones in Liaoning area was analyzed,the results showed that:Huanghuai cyclones moved eastward to match the high ahitude cold eddy in this precipitation process and form deep convergence system,whieh in turn produces a wide range of heavy rain weather,warm wet southwest in low level jet not only provided the water vapor transportation conditions,and also provided the dynamic conditions for the heavy rain and strong winds.During this Huanghuai cyclones heavy rain,energy horizontal conveying and vertical exchange promoted the development of eonvection,in favor of maintain and strengthen rainfall and winds.
