| 摘 要： | 利用MICAPS、NCEP的grib 1x1°、MM5V37模式运行输出等资料,通过天气形势和物理量诊断分析的方法,对造成"05.6"华南致洪暴雨各尺度天气系统进行综合分析。结果表明:该次暴雨过程是在副热带高压、南亚高压、高空槽等大尺度天气系统有利配置的环流形势下,低涡、切变线、静止锋、西南暖低压等天气尺度及中小尺度系统得到发展,各尺度天气系统相互作用下产生的。暴雨落区位于高空槽前、南亚高压脊线反气旋曲率最大处、中低层低涡切变的东南侧和地面静止锋附近。高低空急流相互耦合在这次暴雨的发生过程中起到了关键的作用,高低空急流轴之间的区域是高空辐散区与低空辐合区相配合区域,是强暴雨落区。

| Abstract: | By using the 1x1° MICAPS、NCEP data and the MM5V37 model data,based on the analysis of the weather situation and the physical diagnosis methods,The various-scale weather systems which caused the rainstorm in south china in June 2005 were analyzed.The results showed that,by the favorable configuration of the large-scale weather systems such as Subtropical high,South Asia high and high-altitude trough,the weather scale and mesoscale systems such as vortex,the shear line,stationary front and southwest warm low ... |
