Abstract
A dynamic ice model has been developed for use in the short-term (order of several days at most) prediction of the pack ice movement on the partially ice-covered shallow arctic regions. In this model, the pack ice has been treated as a continuum and thermodynamic effects, vertical gradient of the sea water flow and ice-ice interactions are neglected. Finite difference formulations of the sea water flow and the pack ice movement have been formed using the MacCormack predictor-corrector scheme. In order to avoid the numerical diffusion of ice mass, the authors adopt a semi-Lagrangian type mass transport system. Numerical simulations were performed for some simplified ocean conditions as well as for an actual ocean condition. The results indicated that the present method was rational enough to simulate the movement of pack ice.
