Evaluation of an eddy-permitting finite-element ocean model in the North Atlantic
A new version of the 3D finite-element primitive-equation oceanmodel (FEOM) based on tetrahedron partitioning of the computational domain isapplied to simulate the North Atlantic circulation at eddy-permitting resolution(0.2-2 degrees). It relies on a horizontally refined mesh in regions of steeptop...
