position of the center of the forcing region, x w and y w are the widths of the forcing region, and x t and y t are the tapering extent of the forcing region. Unless specified differently, the forcing region is centered in the middle of the basin ( x 0 , y 0 ) = (70°, 0°). The other parameters are taken by default as x w = 20°, y w = 15°, x t = 5°, and y t = 2°. Note that the exact location of the forcing region does not influence the outcome of the simulations. As the barotropic

an updated version of the Drakkar forcing sets described by Brodeau et al. (2010) . The ORCA12 simulation is forced by an interannually varying atmosphere over the period 1958–2012. The 5-day averages of model variables are stored and used to diagnose eddy fluxes. The atmospheric temperature, humidity, and winds are prescribed as well as the downward radiative fluxes. Turbulent heat fluxes and outgoing longwave radiation are calculated using the model sea surface temperature and bulk formulas

1. Introduction The Atlantic meridional overturning circulation (AMOC) consists of two main cells that extend across the whole latitudinal range of the basin. In the upper cell, warm surface waters are advected northward; they progressively lose their heat to the atmosphere in the northern basin and become denser and sink at middepth at high latitudes to feed the southward return flow of the North Atlantic Deep Water (NADW). In the bottom cell, Antarctic Bottom Water (AABW) enters the basin

c ). We conclude with a brief description of the two intermediate solutions (solutions 1.5 and 1.8) to help to understand the differences between solutions 1 and 2. a. Upper-ocean circulation and DEIV Figure 5 shows the 5-yr mean, near-surface, zonal current and EKE from observations (top panels) and in solutions 1 and 2 (middle and bottom panels, respectively). The South Equatorial Current (SEC), the North Equatorial Countercurrent (NECC), and a fraction of the North Brazil Current (NBC) are
