Abstract/Summary

The standard way in which the sea-ice dynamics equation is used in models assumes that the wind stress and ocean drag do not depend on the sea-ice concentration. It is demonstrated that this assumption is inconsistent with the free-drift limit, and how great an effect it has in practice is examined. By examining the momentum balance in the free-drift limit, the authors determine the proper area scaling for the forcing terms, thereby obtaining a more accurate solution, particularly in low-ice-concentration regions.
