Abstract
This study simulated the process of storm surge in the Eastern China Sea (ECS) during typhoon Lekima, based on the MIKE3 wind-surge model driven by the reconstructed typhoon wind field, which was calculated by the Holland empirical formula. The results show that, affected by shoreline and topography, the storm surge in the Hangzhou Bay and the Taizhou Bay can be more than 3.0 m during typhoon Lekima. During the typhoon, the maximum storm surge on the right side of the track was relatively larger than that on the left side, especially along the coast. And the value of maximum current speed was more than 2.5 m/s, which can be obtained in the coast of Zhejiang. The storm current speed at stations presented logarithmic distribution along the depth generally, either the astronomical tide or storm tide. The vertical structure of current velocity responded to typhoon Lekima presented obvious layered distribution. The value of current speed inner the layers was more than that in the side of the layer.
