Abstract This study uses a sector configuration of an ocean general circulation model to examine the sensitivity circumpolar transport and meridional overturning changes in Southern Ocean wind stress global diapycnal mixing. At eddy-permitting, finer, resolution, forcing magnitude is drastically reduced. sufficiently high there little or no stress, even limit wind. In contrast, continues vary with but reduced stress. Both continue diffusivity at all resolutions. The becomes less sensitive higher although always remains. more change when resolution enough permit mesoscale eddies.
