Wave-tide-surge coupled model simulation for Typhoon Maemi

Reasonably accurate predictions of wave heights, current and elevations during storm events are vital information for marine operations and design of offshore and coastal structures in the surrounding seas of Korea Peninsula.Ocean circulation and wind-wave models have traditionally been run separately, but recent researches have identified potentially important interactions between current and wave motions.The coupled tide-surge and the WAM wave models at the atmospheric boundary layer and bottom boundary layer around the Korea Peninsula are applied for the Typhoon Maemi (0314) event.Communication between the models is achieved using MPI.Results are compared with coastal tide gauges and moored wave buoys and comparisons are also made between wave computations from the coupled model and the independent third generation wave models.Results suggest that applying the tide-surge-coupled model can be an effective means of obtaining wave and storm surge predictions simultaneously.
