REMO-MPIOM coupled model

The coupling between the REMO atmosphere model and the MPI-OM ocean model was carried out using the OASIS coupler. OASIS is used for variables exchange and for coupling time synchronization only. A conservative bilinear interpolation routine is integrated in the MPIOM model to interpolate fields between REMO and MPIOM model grids. The HD model makes its own interpolation for REMO fields. REMO calculates heat, freshwater and momentum fluxes for each grid box and receives in turn SST, sea ice thickness and compactness from the ocean model. The atmosphere-ocean coupling frequency is set to 2 hours and the calculation of the river routing is every 24 hours.
