The northward heat transfer by the Meridional Overturning Circulation (MOC) is one of the main mechanisms that drive Earth's climate. Current knowledge in relation to and their mechanisms have been described primarily through robust numerical models. Recent studies suggest that easterly trade winds have strengthened, causing warm water to pile up in the western Pacific, the water seeps between the islands of Indonesia and into the Indian Ocean, bringing heat with it. Which results in an increase in the last decade in which 70% of the overall ocean this heat gain within the first 700m of water column, which makes Indian a heat storage basin. In order to help understand the variability of the global transport of heat and mass with focus on the role of Atlantic ocean in global dynamics, an international effort is made in the South Atlantic through the SAMOC project (FAPESP: 2011/50552-4) has been set forth with the endorsement of CLIVAR. This program includes the monitoring of meridional fluxes across a transatlantic line along 34.5oS, and the conduction high-resolution numerical simulations in seeking to respond to new global redistribution of heat, the impact on the MOC, and the role of the Atlantic Ocean. Currently a global simulation has been completed in LABMON (IO-USP), with a horizontal resolution of 1/12 of a degree and 32 vertical layers. The work being developed aims to recognize the variability of inter-oceanic transport Pacific-Indian, and the impact on the Agulhas leakage. (AU)
