  abstract = {{S}ynoptic intensification or relaxation of upwelling favorable winds are major sources of variability in eastern boundary upwelling systems. {T}his study aims to investigate their impact on the planktonic ecosystem of the {S}outh {S}enegalese {U}pwelling {S}ector ({SSUS}), located south of the {C}ape {V}erde peninsula over a wide and shallow continental shelf. {N}umerical experiments using a three-dimensional coupled physical-biogeochemical model with four plankton functional types simulated the response of the coastal planktonic ecosystem to idealized synoptic (similar to 10 days) wind intensification and relaxation of the same amplitude. {W}e find that these perturbations induce spatio-temporal oscillations of plankton concentrations. {Z}ooplankton response occurred with a time lag that manifests itself in space as an equatorward/downstream shift in distribution relative to phytoplankton. {O}verall, the transmission of the synoptic perturbation from the physics to zooplankton is characterized by a damping in relative anomalies. {A}ll these elements and the weakness of the asymmetries in the biogeochemical/planktonic ecosystem responses between intensification and relaxation events support the hypothesis that synoptic variability has limited impact on the climatological state of low-latitude upwelling systems such as the {SSUS}.},
