1. Extreme events (droughts, floods, cyclones,
marine heat waves) impacting Africa are linked
to natural modes of variability in the ocean
and amplified by climate change.
2. The Indian Ocean is warming faster than
global oceans and will continue to warm even
after emissions reach NetZero, having severe
consequences on the African conti...
Cette thèse avait pour objectif de mieux comprendre le rôle de la dynamique océanique et atmosphérique régionale sur le fonctionnement de l’upwelling ouest africain. La première partie est consacrée à l’étude du cycle saisonnier, de la dynamique et de l’origine des masses d’eau du courant de bord qui alimente l’upwelling ouest africain. Ce courant...
The regional ocean circulation along the Southern Senegal shelf is studied using a numerical model for varying forcing fields during the upwelling season (November-May). The main objective is to study the shelf circulation of the marine environment in the Southern Senegal Upwelling Shelf (SSUS), the Lagrangian pathways by which waters are transport...
The West African seaboard is one of the upwelling sectors that has received the least attention, and in situ observations relevant to its dynamics are particularly scarce. The current system in this sector is not well known and understood, e.g., in terms of seasonal variability, across-shore structure, and forcing processes. This knowledge gap is a...

With the help of an eddy-permitting NEMO (Nucleus for European Modeling of the Ocean) numerical simulation and dataset from the COPERNICUS observation program, we explore the subsurface dynamics and circulation of the northeast Atlantic ocean (5oN-20oN-15oW-30oW). This area is characterized by a slow subsurface circulation shaped by several importa...
The northeastern Tropical Atlantic sea surface temperature (SST) becomes very warm in boreal summer, north of the seasonal equatorial cold tongue, with a maximum in the vicinity of the InterTropical Convergence Zone (ITCZ). The ITCZ has a significant contribution in the functioning and partitioning of the water cycle over the ocean, but also over W...
