摘要
通过对2014年6月5-7日克什克腾旗一次高空低涡影响下的降水天气过程的分析,揭示了该过程发生发展的成因。结果表明:高空低涡是导致此次降水过程的主要影响系统;鄂霍次克海阻高的阻挡作用,使得系统移动缓慢,影响时间较长;高空干冷空气侵入、高低空急流的耦合作用为此次降水过程提供了充足的水汽供应及强烈的上升运动。
The occurrence and development causes of a severe rainfall weather process that happened in Hexigten Banner from June 5th to 7th 2014was revealed in this article. The results showed that upper-level low vortex was the main influence system for this weather process, Blocking function of Okhotsk Sea blocking high made the system move slowly and last for a long time, The invasion of upper dry cold air and the coupling of upper and lower jets provided abundant moisture and strong ascending motion for this rainfall process.
