摘要:
利用常规观测资料、自动站雨量资料以及6h一次的NECP FNL分析资料(水平分辨率为1°×1°)等,对2016年1月27日20时~28日20时和2013年12月13日20时~16日20时玉林市两次冬季暴雨过程进行诊断分析,结果表明:两次冬季暴雨过程均主要受南支槽东移和切变线的影响,西南气流为这两次过程提供了大量的水汽。低层辐合高层辐散促进上升运动发展,触发了大气层结的不稳定度,而K指数对暴雨的预报有一定的指示作用。
Abstract:
Based on the conventional observation data, the automatic stations rainfall data and NCEP FNL (Final) (1°×1°) every six hours, two winter rainstorm processes in Yulin of January 27th -28th in 2016 and December 13th to 16th in 2013 were analyzed. The results show that:the two winter rainstorm processes are mainly influenced by eastward southern trough and shear line, and the southwest wind provides large amount of water vapor. Low-level convergence and high-level divergence promoted the development of upward movement, and triggered the instability of the atmosphere. So the K index has certain indicative function in forecasting rainstorm.
