Sensitivity of basinwide meridional overturning to diapycnal diffusion and remote wind forcing in an idealized Atlantic southern Ocean geometry
Recent numerical experiments indicate that the rate of meridional overturning as-sociated with North Atlantic Deep Water is controlled both by mixing and by windstress in the Southern Ocean, where the zonal periodicity of the domain alters the nature of the ow. We nd a simple approximate expression...
