On a minimum set of equations for parameterisations in comprehensive ocean circulation models
The complexity of comprehensive ocean models poses an important question for parameterisations: is there a minimum set of equations that should be parameterised, on the one hand, to reduce the development to a minimum, and, on the other hand, to ensure an accurate representation of large-scale flow...

For this, we considered a North Atlantic configuration of the MIT general circulation model and studied contributions of different model equations to the accuracy of representation of the Gulf Stream at low resolution. Our results suggest that it is enough to parameterise only the tracer equations for temperature and salinity and leave the other equations in the hydrodynamic part, as well as the atmospheric model unmodified. |
