台风“玛姬”(9903)数值模拟试验

NUMERICAL SIMULATION EXPERIMENTS OF THE TYPHOON MAGGIE (9903)

通过对台风“玛姬”(9903)个例进行数值模拟,探讨了海温和地形作用对台风“玛姬”(9903)路径的影响,分析了环境气流、台风非对称结构与台风移动路径之间的关系。结果表明:海温对台风“玛姬”(9903)路径有一定的影响,地形作用对台风“玛姬”(9903)路径的影响不可忽视,台风非对称结构对9903号台风异常路径的作用非常重要。

Numerical simulation experiments for the case of typhoon MAGGIE (9903) were carried out. The influence on typhoon MAGGIE (9903) track by SST and topographic forcing were studied, and the relation between environment flow, typhoon asymmetric structure and typhoon moving path was analysed. The results indicate that SST have some influence on typhoon track, and the influence of topographic forcing on typhoon MAGGIE (9903) track is not neglectable. The typhoon's asymmetric structure is an important factor in its abnormal track.
