Abstract
Eddy-resolving ocean models allow for a better representation of mesoscale structures in the ocean. In this study we present a multi-model assessment of the subpolar North Atlantic, including historical simulations from a first generation of coupled eddy-resolving climate models. Four eddy-resolving models (with nominal horizontal resolutions of ~ 10 km in the ocean) have been considered: EC-Earth3P-VHR, MPI-ESM1-2_ER, CESM1-CAM5-SE-HR, and HadGEM3-GC31-HH. Their historical simulations follow the protocol of the High Resolution Model Intercomparison Project (HighResMIP), and have been compared with 39 historical simulations of non-eddy-resolving climate models from the Coupled Model Intercomparison Project Phase 6 (CMIP6), to thus determine whether resolving the ocean mesoscale makes a difference in the representation of the subpolar North Atlantic. In particular, we explore whether eddy-resolving models are better than the standard CMIP6 models at reproducing observed properties and variability in the subpolar North Atlantic, from the representation of mean state temperature and salinity biases, to the stratification and mixing in the regions of deep water formation, the position, strength and meridional transitions of the Gulf Stream current, and the mean state and variability of the Subpolar Gyre circulation and the Atlantic Meridional Overturning Circulation. This model validation will help us to detect potential lingering biases in both HighResMIP and CMIP6 models, and uncover new processes and mechanisms resolved in the eddy-rich models that might have remained masked in eddy-parameterized models.
