The Effect of Storm Surge on Three-dimensional Tidal Current Characteristics: A Case Study of “Lekima”

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