The ocean circulation is driven by a combination of winds and surface buoyancy fluxes. We run a number of experiments with varied surface forcings and look at the spatial variations in ocean circulation on short and long time-scales.
We realise that we cannot impose our desired boundary conditions accurately without specifically imposing the fluxes. We begin with a 1 degree ocean-only model which is forced via fluxes obtained from a control simulation. To kickstart, we are beginning with the following time mean surface fluxes:
Wind stresses in x and y directions,
Shortwave radiation,
Longwave radiation,
Sensible heat,
Latent heat,
Surface salinity restoring,
Precipitation (Liquid + Frozen),
Runoff
These fluxes are enough for a start, with plans to add surface pressure due to ice and atmosphere at a later stage. Some more future works include:
Using time varying fluxes,
Using an eddy-permitting, or even an eddy-resolving ocean model for the simulation.
