  abstract = {{C}hlorophyll-a concentration ({C}hl-a) observed by satellite shows a marked seasonal and interannual variability in the tropical {A}tlantic. {T}his study analyzes how the remotely sensed surface {C}hl-a responds to the leading boreal summer climate modes affecting the interannual tropical {A}tlantic variability over 1998-2018, corresponding to a positive {A}tlantic {M}ultidecadal {O}scillation phase. {W}e show that the {A}tlantic {Z}onal {M}ode ({AZM}) and the {N}orth {T}ropical {A}tlantic {M}ode ({NTAM}) significantly drive the interannual surface {C}hl-a variability in the equatorial {A}tlantic, with different timings and contrasted zonal modulation of the cold tongue. {T}he {AZM} involves remotely forced wave propagations favoring upwelling in the east and {C}hl-a modulation in the core of the cold tongue. {I}nstead, the impact of the {NTAM} is mainly in the west, in response to locally forced pumping that modulates the western extension of the cold tongue. {S}uch conditions can affect the marine food web, inducing significant variations for ecosystem functioning and fisheries.},
