Abstract: Because of geographic circumstances storm surges in the Taiwan straits,are quite characteristic and typhoon strikes are frequent.Using crossed gries,a semi-implicit difference scheme and wind field computations based on the model of a moving typhon's wind field,non-linear numerocal computations have been made.forthe storm surges formed from the typhoons which directhy strike the Taiwan straits along three main tracks.The close correlation between computations and observations confirms the correct choice of the difference scheme stability and boundary conditions by the anchors of this paper.the paper depicts the peculiar life history of storm surges in the Jaiwan straits and dernonstrates that typhoon tracks,typhoon intensities and bottom friction have significant influence upon storm surges in this strait.
