Main objective: Study the ocean variability and scale interactions since 1950. Hierarchy of numerical models: Global ocean (horizontal resolutions: 2°, 1/2°, 1/4°) North Atlantic/Nordic Seas basin (1/4°, 1/12°). NEMO system(5): OPA9-LIM explicit simulation of the 3-dimensional ocean circulation, seaice, 14C and CFC tracers. Surface forcing : momentum, heat and water fluxes computed online via bulk formulae from prognostic model SSTs and atmospheric variables (wind, temperature, specific humidity).
