【 摘 要 】

A coupled tide-surge model, validated for the Typhoon 7203, is used to construct 20 synthetic storm surge cases without and with tides by increasing wind speeds in the Bohai Sea, Yellow Sea and East China Sea. Simulations of Typhoon 7203 and synthetic storm surges are used to study the extreme water elevations at 10 tidal stations along the coast, as well as to evaluate the impacts of increasing wind speeds and tide-surge interactions on storm surge elevations. Results indicate that the increasing wind speeds by 39% can result in at least 103% higher extreme water elevations at 10 tidal stations. Furthermore, the largest differences between storm surge elevations without and with tide-surge interactions can reach 76 and 89 cm at YingKou and LianYunGang tidal station for 60% increase in wind speed, respectively.
