Ocean meridional overturning mass-stream function anomaly of global mean (a) and ocean basins (b through c). The abscissa is latitude in degrees and the ordinate is water depth in meters. Notice that depth is unevenly distributed. The overturning mass-stream function anomaly is in kgs−1. MOC weakens in the upper ocean whereas the AABW is enhanced. It is of note that MOC change in the Pacific and Indian Oceans are different in MPI and MRI.
