:numref:`large-scale-circ` shows the pattern of ocean currents at the surface of a 4° global ocean model run with 15 vertical levels. Lopped cells are used to represent topography on a regular lat-lon grid extending from 70°N to 70°S. The model is driven using monthly-mean winds with mixed boundary conditions on temperature and salinity at the surface. The transfer properties of ocean eddies, convection and mixing is parameterized in this model.
Pattern of surface ocean currents from a global integration of the model at 4° horizontal resolution and with 15 vertical levels.
:numref:`large-scale-circ2` shows the meridional overturning circulation of the global ocean in Sverdrups.
Meridional overturning stream function (in Sverdrups) from a global integration of the model at 4° horizontal resolution and with 15 vertical levels.
