摘要:
利用MICAPS资料和NCEP的1°×1°FNL分析资料,对2014年6月11日钦州市出现的特大暴雨过程的天气系统、物理量场进行诊断分析。结果表明:此次特大暴雨过程主要受低涡、低层切变线和高空槽的共同影响,具有局地性强,强降雨持续时间长的特点,低层水汽通量的辐合提供了较为充足的水汽条件,特大暴雨的出现与垂直速度、涡度散度、假相当位温θse以及K指数这些物理量都有很好的对应,钦州上空聚集着大量不稳定性能量,剧烈的垂直上升运动和南压的切变线有利于暴雨天气的触发。
Abstract:
Based on the MIC APS data and NCEP l°×l° FNL analysis data, the weather system and physical quantity field of rainstorm process on June 11, 2014 in Qinzhou were diagnosed and analyzed. The results show that the super rainstorm process is mainly affected by the combined effect of vortex and shear line in lower level and upper level trough with a strong local, long duration time, the low-level moisture flux convergence provides more favorable moisture conditions, torrential rain and vertical velocity, vortices, divergence, θse and K index these physical quantities have good correspondence, a large instability energy, severe vertical ascending motion and southward shear line are conducive to the triggering of rainstorm weather.
