Última Dynamique de bord ouest en mer d'Arabie ArchiMer Vic, Clement. This PhD aims to investigate some western boundary processes in the Arabian Sea : (i) the life cycle of the socalled Great Whirl, a persistent mesoscale eddy; (ii) the dynamics of the Persian Gulf outflow, a marginal sea dense outflow; and (iii) the seasonal Oman upwelling, a coastal upwelling forced by summermonsoonal winds. The cornerstone of all these phenomena is their locationat a western boundary, which makes then being influenced by both localforcing (e.g., monsoonal winds) and remote forcing (Rossby waves and wesward drifting eddies). Specifically, the later are expected to impact the western boundary dynamics since the low latitude of the Arabian Sea implies a fast westward propagation of long Rossby waves and eddies. Moreover, waves are...

The Great Whirl (GW) is a persistent anticyclonic mesoscale eddy that is observed seasonally in the Arabian Sea during a period embedding the 3 months of the southwest monsoon (June–July–August) at a quasi-steady location. Its dynamics remain unclear despite it being one of the largest coherent vortices in the world ocean. Realistic regional numerical experiments using ROMS are performed to investigate the life cycle of the GW, which is not well resolved by sparse available in situ measurements in the region. Using a set of sensitivity experiments and an accurate temporal characterization of the eddy properties (including position, radius, depth, and vorticity) we (i) confirm the role of basin-scale downwelling Rossby waves in the GW generation, (ii)...
