| 摘 要： | 本文以９０１５号热带气旋登陆后造成的省淮以南大暴雨天气为例，与８闪一般暴雨天气的热力动力条件进行对比，分析它们之间的异同点，并利用二维点尺度力学模式对地面中尺度锋区引起民环流进行模拟试验，结果表明，在热带气旋伸向东北部一条辐合线的偏北旗帜的中尺度锋区驱动扰动涡旋，在涡旋的上升部位可对大暴雨有增幅作用。

| Abstract: | The thermodynamic and dynamic conditions of 8 ordinary storm rainfaU weather caseswere compared with those of tropical cyclone,for example, No. 9015, which caused greatstorm rainfall at South of Huaihe river in Jiangsu Province. Two dimensional meso-scaledynamic model was used to simulate the circulation at surface meso-scale front area. Theresults show: meso-scale front area in tropical cyclone can drive disturbed vortex to thenorth of convergence line in the northeast of tropical cyclone. Great storm rainfall amplitudecan be increased in the rising area of vortex. |

| Keywords: | tropical cyclone great storm rainfall comparative analysis reasons for amplitude of increase |
