Sea Ice Modelling
On the geophysical scale sea ice is a thin, broken layer on the polar oceans which is modified in thickness and compactness by dynamic and thermodynamic processes. Sea ice represents the boundary between the two much larger geophysical fluids, the atmosphere and the ocean, and, therefore, influences their interaction considerably. Sea ice is described as a two-dimensional deformable solid material with a specific geophysical rheology. The presentation will focus on the optimization of sea ice dynamics, and on model verification using satellite data and buoy trajectories. Applications to past and current sea ice anomalies will be shown, including the interaction with atmosphere and ocean.
