description | Version 2 of the unstructured-mesh Finite-Element Sea ice–Ocean circulation
Model (FESOM) is presented. It builds upon FESOM1.4 (Wang et al., 2014) but
differs by its dynamical core (finite volumes instead of finite elements),
and is formulated using the arbitrary Lagrangian Eulerian
(ALE) vertical coordinate, which increases model flexibility. The model
inherits the framework and sea ice model from the previous version, which
minimizes the efforts needed from a user to switch from one version to the
other. The ocean states simulated with FESOM1.4 and FESOM2.0 driven by
CORE-II forcing are compared on a mesh used for the CORE-II intercomparison
project. Additionally, the performance on an eddy-permitting mesh with
uniform resolution is discussed. The new version improves the numerical
efficiency of FESOM in terms of CPU time by at least 3 times while retaining
its fidelity in simulating sea ice and the ocean. From this it is argued that
FESOM2.0 provides a major step forward in establishing unstructured-mesh
models as valuable tools in climate research. |
