Discretization of sea ice dynamics in the tangent plane to the sphere by a CD-grid-type finite element
We present a new discretization of sea ice dynamics on the sphere. The approach describes sea ice motion in tangent planes to the sphere. On each triangle of the mesh, the ice dynamics are discretized in a local coordinate system using a CD-grid-like non-conforming finite element method. The develop...
