| 摘 要： | 以大尺度环流背景为基础,从中尺度抬升系统、物理量场、MCC云团活动、地形作用等多角度分析了2004年7月16~17日暴雨西南东北向特殊落区成因,结果表明:500 hPa蒙古高压带和副高所形成的气旋性辐合带位置和走向对中尺度抬升系统的移向有重要的引导作用;低涡路径、急流轴位置、地面低压倒槽移向和水汽通量等值线密集区与暴雨落区有较好的对应关系;地形的谷口效应和抬升作用对强降水的产生有明显的协助作用。

| Abstract: | Basing on the background of macro - scale circulation, We analyze the forming of especial storm area from southwest to northeast in July 16 to 17 ,2004 through meso - scale lifting system ,physical vector field and the activity of MCC cloud,function of terrain and so on, and indicate that the situation and the direction of the cyclonic convergence zone formed by 500hPa Mongolia high belt and Subtropical high have important introductory effect on the movement of meso - scale lilting system; the track of low vortex ,the situation of axis of jet flow ,the movement of inverse trough of low pressure and the equiscalar line dense district of moisture flux have finer corresponding relation with the rainstorm area. |
