… A numerical simulation of the tropical Atlantic Ocean indicates that surface cooling in
upwelling zones of the Gulf of Guinea is mostly due to vertical mixing. At the seasonal scale,
the spatial structure and the time variability of the northern and southern branches of the
South Equatorial Current (SEC), and of the Guinea Current, are correlated with the timing
and distribution of turbulent heat fluxes in the Gulf of Guinea. Through modulation of the
velocity shear at the subsurface, these … The goal of the present paper is to demonstrate …
