| 摘 要： | 2011年7月11～-18日江苏出现了连续降水天气,其中伴随着多次暴雨到大暴雨过程。利用micaps常规观测资料、卫星云图等资料,对这次过程初7月11日在江苏中部出现的区域性暴雨进行分析,通过对大尺度环流场、物理量场和中尺度系统的分析,得出本次暴雨是在鞍形场的稳定环流背景下,受850 hPa和700 hPa切变线和地面倒槽的共同影响造成的,水汽条件和热力条件都有利于暴雨的发生和持续,地面中小尺度辐合系统是这次暴雨的触发机制。

| Abstract: | During 11th-18th July 2011 the continuous wet weather had happened over Jiangsu Province,which accompanied the repeatedly rainstorm or heavy rainstorm process.By using the micaps conventional observation data and satellite cloud data,the regional rainstorm in the middle of Jiangsu on 11 July was analyzed.Through analysis of large scale circulation,physicals and the mesoscale system,the heavy rain occurred under the influence of the shear line at 850 hPa and 700 hPa level,the surge chamber on surface while large-scale circulation of saddle field was stable.Water condition and energetics condition were advantageous to the occurrence and the sustainability of the rainstorm.Mesoscale convergence system on surface touched off this rainstorm. |
