The decadal impact of including ocean surface currents in the bulk formulas on surface air-sea fluxes and the ocean general circulation is investigated for the first time using a global eddy-permitting coupled ocean-sea ice model. It is found that including ocean surface currents in air-sea flux calculations weakens the strength of the global ocean circulation in a number of ways. As a result, the northward ocean heat transport decreases, which, in turns, leads to a lower sea surface temperature and reduced surface heat loss in the northern North Atlantic. Additional sensitivity model experiments demonstrate that it is including ocean surface currents in the wind stress calculation that dominates this decadal impact, with including ocean surface currents in the turbulent heat flux calculations making only a minor contribution.
