  abstract = {{U}pwelling processes bring nutrient-rich waters from the deep ocean to the surface. {A}reas of upwelling are often associated with high productivity, offering great economic value in terms of fisheries. {T}he sensitivity of spring/summer-time coastal upwelling systems to climate change has recently received a lot of attention. {S}everal studies have suggested that their intensity may increase in the future while other authors have shown decreasing intensity in their equatorward portions. {Y}et, recent observations do not show robust evidence of this intensification. {T}he {S}enegalo-{M}auritanian upwelling system ({SMUS}) located at the southern edge of the north {A}tlantic system (12 degrees {N}-20 degrees {N}) and most active in winter/spring has been largely excluded from these studies. {H}ere, the seasonal cycle of the {SMUS} and its response to climate change is investigated in the database of the {C}oupled {M}odels {I}nter comparison {P}roject {P}hase 5 ({CMIP}5). {U}pwelling magnitude and surface signature are characterized by several sea surface temperature and wind stress indices. {W}e highlight the ability of the climate models to reproduce the system, as well as their biases. {T}he simulations suggest that the intensity of the {SMUS} winter/spring upwelling will moderately decrease in the future, primarily because of a reduction of the wind forcing linked to a northward shift of {A}zores anticyclone and a more regional modulation of the low pressures found over {N}orthwest {A}frica. {T}he implications of such an upwelling reduction on the ecosystems and local communities exploiting them remains very uncertain.},
