| By taking into account salinity measurements and consequently mean residence time, current measurements, tidal computation with a 2-D model and wind induced currents provided by a 3-D model, a global diagram of residual flow in Seine Bay is given. Main patterns are exhibited: density currents in the eastern part of the bay, off the Seine Estuary, wind induced circulation, especially along the coast and over the Channels, and tidal residual patterns induced by topography. |

| Using idealized and realistic high-resolution primitive equation models, we explore the annual and semi-annual period fluctuations in the deep equatorial Atlantic Ocean. The deep seasonal variability derives its energy from the equatorial zonal wind stress component and the wind energy reaches the deep layers by means of vertically propagating Kelvin and Rossby waves. The first meridional mode (l = 1) annual Rossby wave reaches the western boundary while the other Rossby waves directly propagate toward the bottom. A deep Kelvin wave is generated by the reflection of the incoming l = 1 annual Rossby wave at the western boundary. Due to the complexity of the surface layers in the non-linear simulations, one cannot separate the waves generated at the... |
