Abstract : At the ocean surface, satellite observations have shown evidence of a large spectrum of waves at low latitudes, responsible for a large part of the surface variability. However, very little is known on the existence and properties of the deep variability. Most of the subsurface observations rely on localized measurements, which do not allow […]

Abstract: We investigate the lag between warm interannual Sea Surface Temperature (SST) events in the eastern equatorial Atlantic, the Atlantic Niños, and the occurrence of Benguela Niños along the southwestern Angolan coast. It is commonly agreed that both events are associated with equatorial and subsequent coastal-trapped wave propagations driven remotely by a relaxation of the trade-winds. […]
