| 摘 要： | 通过对2007年9月18-20日,青岛市破历史纪录的全区性大暴雨过程的天气实况、环流形势分析、物理量诊断和雷达资料分析表明,过程出现在西风槽、副热带高压和台风韦帕相互作用形成的高湿度、强上升运动区中.过程前期的降水,主要是高层的强抽吸起作用,降水较弱."韦帕"使得低层的辐合抬升进一步加强,上升运动更为强烈.对流层上层冷空气的活动,使得大气的层结不稳定进一步加强.3个系统的耦合,形成了这次大暴雨过程.过程的中小尺度扰动活跃.雷达资料分析发现,在低层一条线状呈气旋性弯曲的辐合抬升带,为海陆温差引起的陆风效应造成的海陆锋,是一条强降水带,伴随有强水平风切变.

| Abstract: | A heavy rainstorm happened in Qingdao from September 18 to 20,2007,which ex- ceeded the historical record.The real-time data,circulation characteristic and Doppler radar data were used to analyze the heavy rainstorm process.The results show that there was a strong vapor convergence at low level.At the beginning the precipitation was caused by the strong pumping at high level and was rather weak.Typhoon Wipha strengthened the convergence lifting.The activ- ity of cold air at high level strengthened the insta... |
