The Meridional Overturning Circulation (MOC) mixes heat and salinity among ocean basins and between deep and shallow waters. Global climate effects, including moderation of the climate of western Europe, are extensive. Changes in the strength of the MOC could thus have dramatic impacts for local to regional climate change, but evidence for systematic changes is, to date, equivocal. Analysis of the residuals between a coarse resolution ocean model and a model with a localized fine-resolution grid shows that the input of warm and salty water transferred around the southern tip of Africa (termed the Agulhas leakage) contributes strongly to the strength of the MOC.
