| 摘 要： | 利用常规资料、数值预报产品资料、多普勒雷达资料对2011年7月29日暴雨过程进行多尺度分析,并对该过程的成因进行探讨.结果表明:副热带高压东退,蒙古低槽东移引导冷空气南下,与中层的西南低空急流人字切变,低层的中尺度辐合线、中尺度低压,地面冷空气相互作用,不断激发对流系统,促成了此次暴雨过程的维持和发展.

| Abstract: | We analysis the storm on July 29th, 2011 at multi-scale with routine data, numerical forecast products data and Doppler Radar data and discussed the causes of the process. The southward cold air, which was guided by eastward subtropical high and mongolian low slot sheared in herring bone with southwest low-level jet in middle-level. The low-level mesoscale convergence line and the middle level low pressure interactioned with surface cold air, which inspired convective systems constantly, contributed to the maintenance and developmerit of the storm. |
