| 摘 要： | 选取登路北上,在大连地区造成强降水的热带气旋0509"麦莎",对其影响大连地区期间的环境流场、路径特征及物理量场进行诊断分析。结果表明,稳定的副热带高压及非纬向高空急流与低空急流的耦合,使来自东南洋面的丰沛水汽不断输送到大连地区,且有利于"麦莎"的北上。"麦莎"在北上过程中,没有从中纬度西风槽获得斜压能量,并没有变性加强。同时,借助于卫星云图、多普勒雷达资料,分析"麦莎"暴雨的中小尺度系统,结果表明导致大连地区强降水的主要系统是两个中-β尺度系统,暴雨落区在"麦莎"的东北侧。 |
| 关 键 词： | 麦莎” 热带气旋暴雨 中小尺度 |

| Abstract: | "Matsa"(Tropical Storm 0509) went northward and caused a strong rainstorm to the Dalian.In this article,the environment air flow,the feature of path and the physical fields in the affected area is analyzed to study the characeristic of the"Matsa"rainstorm.Results showed that the steady subtropical high and coupling of non-latitude high-low tropospheric jets transfered ample vapor from Southeastern Pacific surface to the Dalian area,and made favorable conditions for the northward moving of "Matsa".During the period,however,"Matsa" did not acquire baroclinicity energy from mid-latitude westerly trough and its transformation intensification were not enhanced.Meanwhile,based on the data from satellites and dopler radar,the meso-micro scale systems of "Matsa"is analyzed,revealing that it was the two meso-β systems induced the strong rainstorm in the Dalian area."Matsa"rainstorm located at the northeast side of the typhoon. |
| Keywords: | "Matsa" typhoon rainstorm meso-micro scale |
