  abstract = {{T}his study investigates the physical processes controlling the mixed layer buoyancy using a regional configuration of an ocean general circulation model. {P}rocesses are quantified by using a linearized equation of state, a mixed-layer heat, and a salt budget. {M}odel results correctly reproduce the observed seasonal near-surface density tendencies. {T}he results indicate that the heat flux is located poleward of 10 degrees of latitude, which is at least three times greater than the freshwater flux that mainly controls mixed layer buoyancy. {D}uring boreal spring-summer of each hemisphere, the freshwater flux partly compensates the heat flux in terms of buoyancy loss while, during the fall-winter, they act together. {U}nder the seasonal march of the {I}nter-tropical {C}onvergence {Z}one and in coastal areas affected by the river, the contribution of ocean processes on the upper density becomes important. {A}long the north {B}razilian coast and the {G}ulf of {G}uinea, horizontal and vertical processes involving salinity are the main contributors to an upper water change with a contribution of at least twice as much the temperature. {A}t the equator and along the {S}enegal-{M}auritanian coast, vertical processes are the major oceanic contributors. {T}his is mainly due to the vertical gradient of temperature at the mixed layer base in the equator while the salinity one dominates along the {S}enegal-{M}auritania coast.},
