摘要
通过分析 2 0 0 2年第 2 0号热带风暴“米克拉”在广西南部沿海登陆后引发远离台风暴雨的台风倒槽暴雨 ,以及与强降水有关的物理量场的变化、风廓线仪和地面风场的脉动 ,探讨了在台风倒槽与西风槽相结合处以强降水为主的强对流天气发生发展的环境条件。
Investigation was conducted on a heavy rain influenced by the typhoon inverted trough of the tropical cyclone 'Mekkhala'(2002),which landed the southwestern Guangxi Province. The relevant changes of physical variable fields and wind profile and the fluctuation of surface wind fields are analyzed. The environmental conditions for the strong convection that caused local heavy rainfall around the area where the typhoon inverted trough and the westerly trough joined are discussed in detailed.
