摘要:
利用NCEP/NCAR 1°×1°逐六小时的全球再分析资料、风廓线和雷达回波及常规观测资料,对2016年4月23日福建省暴雨过程成因进行了分析。结果表明:西南低空急流和超低空急流是这次暴雨的主要影响系统,暴雨主要位于超低空急流左前侧的辐合区内和地面层辐合线附近,在低层辐合线的东南侧不断有回波生成,回波在西南气流的引导下往东北方向移动,同时超低空急流增强和北推的过程亦是回波开始有组织的发展和往东北移动过程;V-3θ图分析对这次暴雨天气有较好的指导作用;与低空急流相对应的低层正涡
Abstract:
Based on NCEP 1°×1°reanalysis data, wind profile data, Doppler radar and AWS observational data, the warm zone heavy rainfall in Fujian on April 23th was studied by means of physical diagnosis. The results show that:low-level southwest jet
