Última Variabilité décennale de la circulation océanique et modes de bassin: Influence de la topographie et de la circulation moyenne ArchiMer Ferjani, Dhouha. One of the potential mechanisms at the origin of climatic variability on decadal to multidecadal timescales is the thermohaline oscillation corresponding to large-scale and low frequency basin modes that result from the interaction between long planetary waves and fast inertia-gravity waves during the adjustment process. However, most of the studies dealing with this decadal oscillation were carried out in a simplified flat bottom or reduced-gravity quasigeostrophic context. This dissertation aims to study the effect of bottom topography and mean flow on the characteristics of the gravest baroclinic basin modes of variability in a mid-latitude idealized ocean basin. To that end, we make use of a two-layer shallow water (SW) model. Different bathymetries...
