Effects of sea ice on wave energy flux distribution in the Bohai Sea
The wave energy flux distribution in the Bohai Sea during wintertime is re-evaluated based on SWAN with the added sea-ice effect, which is derived from an ice-ocean coupled model, FVCOM. Simulated wave parameters and ice cover agree well with the measured wave data and the MODIS images of sea-ice co...
