Do we require adiabatic dissipation schemes in eddy-resolving ocean models?

Abstract:

Use of horizontal diffusion of temperature and salinity in numerical ocean models causes spurious diapycnal transfers - the "Veronis effect" - leading to erosion of the thermocline and reduced poleward heat transports. The authors derive a relation between these diapycnal transfers and the dissipation of vorticity gradients. An increase in model resolution does not significantly reduce the diapycnal transfers since vorticity gradients cascade to smaller scales and must ultimately be dissipate...
