Specifically, the weather characteristics in the period from 6 to 12 hour before the typhoon made landfall till typhoon leave Taiwan are to be studied. We will explore how the typhoon structure, size, strength, and the synoptic background may cause the variation in the wind and rainfall pattern and the length of duration period of typhoon landfall at Taiwan. We will use the meteorological data available to construct the climatology and use the shallow water model to explore the dynamics of track diffraction during the landfall. We hope to establish a conceptual model for the typhoon landfall forecast purpose.侵台颱風移行預報typhoonduration periodforecast
