Ocean heat uptake occurs through passive advection/diffusion of surface heat anomalies and through the redistribution of existing temperature gradients due to circulation changes. Atlantic meridional overturning circulation (AMOC) weakens in a warming climate and this should slow the downward heat advection (compared to a case in which the circulation is unchanged). However, weakening AMOC also causes a deep warming through the redistributive effect, thus increasing the downward rate of heat propagation compared to unchanging circulation. Total heat uptake depends on the combined effect of these two mechanisms.125 pagesenCopyright 2015 Oluwayemi Anne GarubaPhysical oceanographyClimate changeAtmospheric sciencesClimate changeClimate transient responseOcean circulationOcean heat uptakeOcean modellingMechanisms of ocean heat uptakeDissertation
