| 摘 要： | 利用常规气象资料和卫星云图,结合梧州地面逐时雨量、探空和713天气雷达回波等资料,对2006年6月8日发生在梧州市的特大暴雨过程进行成因分析,结果发现,此次特大暴雨具有典型的中尺度扰动及强对流特征,强降水的主要原因是由一个中尺度对流雨团活动而造成,雨团在移到梧州市时发展并停留约9小时。大尺度背景场分析表明,暴雨发生前梧州即处于有利降水的形势场中,地面中尺度辐合线可能是强对流的触发系统。此外还初步分析了城市周围环境对强降水的增幅作用。

| Abstract: | Using the conventional data and satellite image,combining the per-hour precipitation data,sounding data and 713 radar data,the cause of the rainstorm in Wuzhou city at June 8th 2006 is analyzed.Results indicate that of middle scale disturbance and severe convection are the typical characteristics in this event.The main reason for it is a middle scale convection cloud cluster,which developed and stayed about 9 hours above Wuzhou.The analysis of the large scale background field shows that Wuzhou has been in a pattern that avail precipitation before the rainstorm,and the middle scale convergence line at ground may be the trigger system.Besides,the environment amplitude effect to the severe precipitation is also discussed. |
