I am working to improve the model of the Gulf stream using the NEMO ocean model by looking at the role of the bathymetry on the separation from the coast and subsequent path. The Gulf Stream can be reasonably well represented in higher resolution ocean models, but lacks accuracy in lower resolutions. This indicates the involvement of small-scale processes which cannot be resolved in the coarser models; thought to be triggered by interaction with the bathymetry.
My initial investigation uses barotropic vorticity diagnostics to identify the vorticity provided by the various contributions towards the momentum equation.
