A one-dimensional sea ice-ocean model and the application in the Arctic Ocean are presented. The model includes a multi-layer snow/ice model, a mixed-layer ocean model, and the interfaces between atmosphere and snow/sea-ice, sea ice and sea water, as well as atmosphere and the open ocean. The effects of snow ventilation and blowing snow are also included.
The observational data from the measurements at the ice station of the Surface Heat Budget of the Arctic Ocean (SHEBA) field experiment (Moritz and Perovich 1996) in November and December of 1997 were used to drive and validate the model. The stand-alone simulations show that the surface temperature, thickness of snow and sea ice, sensible heat flux, upward longwave radiation, and temperature, salinity, and density of the ocean mixed layer are well reproduced by the model when the effects of blowing snow and ventilation are included.
