The FESOM-C, the coastal branch of the Finite-volumE Sea ice – Ocean Model (FESOM2). FESOM-C solves 3D primitive equations in the Boussinesq, hydrostatic, and traditional approximations for the momentum, continuity, and density constituents. This model retains many numerical characteristics of FESOM2, notably its finite-volume cell-vertex discretization. However, FESOM-C's dynamical core is distinct, particularly in its approach to time stepping, adoption of a terrain-following vertical coordinate, the inclusion of a wetting/drying option, and the usage of hybrid meshes that integrate triangles and quads and allow high computational efficiency and geometrical flexibility. The numerical scheme of FESOM-C splits the fast and slow motions into barotropic and baroclinic modes. It uses an asynchronous time stepping, assuming that the integration of temperature and salinity is half-step-shifted with respect to momentum. For modeling wetting and drying we use the method proposed by Stelling and Duinmeijer, the algorithm to account for wetting and drying (if an appropriate flag is on) is performed on each time step of the external mode. Three schemes have been implemented in FESOM-C for horizontal advection: upwind, Miura, and MUSCL-type.
