DYNAMIC ANALYSIS OF TYPHOON SURGES ALONG THE COASTS OF ZHEJIANG AND JIANGSU PROVINCES

Based on the numerical model shown in Ref. 1], a dynamic analysis is given for the storm surges caused by the four typhoons (i. e. typhoons Nos. 5310, 5612, 6126 and 6207) on the east coast of Zhejiang and Jiangsu Provinces, in which the contributions of various dynamic factors to local surge elevation are calculated numerically, including the Coriolis force, the atmospheric pressure force, the bottom friction, the local topography and the couple nonlinear interactions between surge current and elevation as well as between surge currents themselves. Moreover, the responses of these factors to different kinds of typhoon tracks and water depths are discussed in more detail, and the effects of grid size on the computed results demonstrated.
