| 摘 要： | 本文用一个β平面准地转正压模式实施了九组试验，研究台湾岛地形对台风移动路径的作用。初始场系根据SPECTRUM和TCM-90期间加强观测资料确定。结果表明:台湾岛地形的引进会使台风路径向右偏移；地形使台风环流的最大风速区向台风中心方向推移，造成台风环流空间尺度减小，这个结构的变化是路径右偏的一个可能原因。

| Abstract: | In order to investigate the effect of the orography of Taiwan island on typhoon tracks, nine numerical experiments are performed using the barotropical vorticity equation with the orographic term. The grid point values of the initial fields are obtained from the dense data of SPECTRUM and TCM-90 Field Experiment by an interpolation method. Results show that the tracks of the model typhoon deviate towards the polar side because of the effect of the orography and that the asymmetric structure has been changed. The positions of the maximum velocities have been shifted towards the typhoon center after introducing the orography, which may be a possible cause for right deviation of the tracks. |
