abstract
Sea ice is sensitively dependent on the fluxes of energy, mass and momentum between the ocean and the atmosphere, making it worth investigating the modification of these fluxes by the respective boundary layers. Complementary to earlier investigations with a coupled sea-ice-oceanic mixed-layer model for the Southern Ocean, the atmospheric forcing in the present investigation is changed from monthly observational data to daily, essentially modelled values computed by an operational numerical weather-prediction model. Applying these computations directly as atmospheric surface forcing to the sea-ice-oceanic mixed-layer model yields (in first order) encouraging results. -from Author
