Abstract:

东北冷涡暴雨一般发生在冷涡发展阶段,冷涡衰退阶段发生暴雨的几率不高,在日常业务预报中往往容易忽视冷涡衰退阶段暴雨的预报,容易出现漏报的现象。作者结合观测资料和数值模拟结果,对2005年6月21日发生在吉林省中东部地区的一次暴雨过程进行分析。结果表明:这次暴雨发生在东北冷涡衰退阶段,强降水区处于非常弱的对流不稳定区,低空不同层次上急流的耦合与脉动,在时间和空间上形成“接力”之势,给雨区带来特定的水汽配置并在雨区上空形成合适的不稳定环境,导致雨区上空湿位涡的强烈增长,在弱对流不稳定和条件对称不稳定的共同作用下,层状云中形成对流并发展,产生了暴雨天气。重力惯性波是暴雨产生的可能触发机制。
