摘要
分析表明：当９６０８台风在福建登陆并往西北行之后，台风东侧东南风和西南风加强并在闽南地区形成暖湿切变，台风西侧的下沉偏北气流南侵加强了闽南地区的湿斜压锋区，提供了中尺度对流云团发生发展的有利条件；台风低压西北方干舌卷入并向南扩展、地面中小尺度辐合系统、地面中尺度能量锋区以及闽南特殊的地形作用均加强了对流云团的发展。
The analysis results showed that after Typhoon 9608 landed on Fujian and moved northwestward,the enhance of the southeast wind and southwest wind at the east side of the typhoon,the warm moisture shear line formed over,southern Fujian,the descend of north wind at typhoon′s west side moving southward and then the enhanced moisture baroclinic front zone in southern Fujian,provided the favourable conditions for developing the mesoscale convective cloud cluster The involement of a dry tongue from northwest of the typhoon and moving southward,the small and mesoscale convergence system at surface,the surface mesoscale energy frontal zone and the special topography at southern Fujian all enhanced the development of convective cloud cluster.
