2° global configuration (ORCA2)
OPA8.2 (Madec, Delecluse et al. 1998). The formulation is based on so-called 'primitive' equations. These equations are derived from Navier-Stokes equations in a stratified fluid with following approximations:
Ocean atmosphere interface
|Flux formulation. The monthly climatological flow of the 120 main rivers is taken into account in the evaporation minus precipitation budget. Daily correction of the global surface fresh water budget. A parameterization of the penetrating heat flux is used.|
ERA40 reanalysis (1979-2001) and ECMWF daily operational analysis (2001-2005) journalière. Zonal and meridional wind stress components, wind module, heat penetrating flux, solar flux, non solar flux, salt flux, evaporation minus precipitation minus runoff.
