The effects on ice-thickness distribution of including ridge-related roughness in the drag parameterization is investigated using a sea-ice dynamic and thermodynamic model. A long-term integration of the sea-ice model forced by a 5 day running mean of daily geostrophic winds and steady but spatially varying ocean currents was performed to construct climatological thickness fields. Compared to a constant drag coefficient model, results that include roughness have a significantly different
more » ... ly different spatial distribution with much thicker ice in the western Arctic. These results match observations better than those where ice roughness was omitted.
