  abstract = {{T}he recurrent occurrences of interannual warm and cold events along the coast of {A}frica have been intensively studied because of their striking effects on climate and fisheries. {U}sing sensitivity experimentation based on a coupled physical/biogeochemical model, we show that the oceanic remote equatorial forcing explains more than 85% of coastal interannual nitrate and oxygen fluctuations along the {A}ngolan and {N}amibian coasts up to the {B}enguela {U}pwelling {S}ystem ({BUS}). {T}hese events, associated with poleward propagations of upwelling and downwelling {C}oastal {T}rapped {W}aves ({CTW}), are maximum in subsurface and controlled by physical advection processes. {S}urprisingly, an abrupt change in the {CTW} biogeochemical signature is observed in the {BUS}, associated with mixed vertical gradients due to the strong local upwelling dynamics. {C}oastal modifications of biogeochemical features result in significant primary production variations that may affect fisheries habitats and coastal biodiversity along the southwestern {A}frican coasts and in the {BUS}.},
