| 摘 要： | 利用常规观测资料、FY-2C卫星云图、NCEP/NCAR再分析资料,对一次西南低涡暴雨过程进行了诊断分析。结果表明,这次暴雨天气过程的主要影响系统有对流层高层南亚高压、中层低涡、低层切变线（低涡）以及台风＂天鹅＂。该过程是由3个接连发生的中尺度对流云团直接造成的,发生在西南低涡闭合涡旋范围内的非对称处。利用WRF_AR... |

| Abstract: | A case of torrential rainstorm process caused by a southwest vortex(SWV) is diagnosed using the observation data,FY-2C satellite image,and NCEP/NCAR reanalysis data.The result shows that the main influencing systems are South Asia High,lee trough,and shear line from the tropopause to near surface in vertical direction.The tropical storm '0907'(Goni) is another key factor in this case.The torrential rainstorm is directly caused by three mesoscale convective cloud clusters continuously,which occurred asymmetr... |
