24 | | -horizontal diffusion on momentum: the eddy viscosity coefficient depends on the geographical position. It is taken as 40000. m2/s, reduced in the equator regions (2000 m2/s) excepted near the western boundaries.[[BR]] |
25 | | -isopycnal diffusion on tracers: the diffusion acts along the isopycnal surfaces (neutral surface) with a eddy diffusivity coefficient of 2000. m2/s.[[BR]] |
26 | | -Eddy induced velocity parametrization with a coefficient that depends on the growth rate of baroclinic instabilities (it usually varies from 15 m2/s to 3000m2/s).[[BR]] |
27 | | -lateral boundary conditions : zero fluxes of heat and salt and no-slip conditions are applied through lateral solid boundaries.[[BR]] |
28 | | -bottom boundary condition : zero fluxes of heat and salt are applied through the ocean bottom. The Beckmann [19XX] simple bottom boundary layer parameterization is applied along continental slopes. A linear friction is applied on momentum.[[BR]] |
29 | | -convection: the vertical eddy viscosity and diffusivity coefficients are increased to 1 m2/s in case of static instability.[[BR]] |
30 | | -forcings: the ocean receives heat, freshwater, and momentum fluxes from the atmosphere and/or the sea-ice. The solar radiation penetrates the top meters of the ocean. The downward irradiance I(z) is formulated with two extinction coefficients [Paulson and Simpson, 1977], whose values correspond to a Type I water in Jerlov's classification (i.e the most transparent water)[[BR]] |
