摘      要：Sea ice can attenuate wave energy significantly when waves propagate through ice *** this study,a third-generation wave model called simulating wave nearshore(SWAN)was advanced to include damping of wave energy due to friction in the boundary layer below the *** the addition of an eddy viscosity wave-ice model,the resulting new SWAN model was applied to simulate wave height in the Bohai Sea during the freezing *** performance was validated with available buoy data near the ice edge,and the new model showed an improvement in accuracy because it considered the ice effect on *** then performed a wave hindcast for the Bohai Sea during a freezing period in the winter of 2016 that had the severest ice conditions in recent years and found that the mean significant wave height changed by approximately 16.52%.In the Liaodong Bay,where sea ice concentration is highest,the change reached 32.57%,compared with the most recent SWAN model *** average influence of sea ice on wave height simulation was also evaluated over a five-year(2013-2017)hindcast during January and *** found that the wave height decrease was more significant in storm conditions even the eddy viscosity wave-ice model itself showed no advantage on damping stronger waves.
