Última Variabilité décennale de la circulation océanique et modes de bassin: Influence de la topographie et de la circulation moyenne 5 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...
