Última Observation de la convection profonde en mer d'Irminger sur la période 2002-2015 par les flotteurs Argo. ArchiMer Piron, Anne. The deep convection events are important because they form the intermediate and deep water masses feeding the global circulation. The Labrador Sea is the main site of deep convection in the North Atlantic Ocean and produces the intermediate Labrador Sea Water (LSW). The Irminger Sea was also cited but was forgotten during decades because of the lack of direct observations. This thesis provides the first description of the Irminger Sea deep convection at basin scale, thanks to the Argo data. Three convective events occurred in the Irminger Sea since 2010. During the 2011-2012 winter, the convection reached 1000 m and is explained by the sequence of the Greenland tip jets. The event of the 2013-2014 winter, reaching 1300 m, is characterized by a strong...

Patterns of interannual variability of the ocean- atmosphere coupled system in the Southern Hemisphere ex- tratropics are studied with a simple dynamical model, in or- der to determine the basic physical processes of interaction independently of tropical forcing. The model used is an at- mospheric quasi-geostrophic model coupled to a "slab" oceanic mixed layer, which includes mean geostrophic advection by the Antarctic Circumpolar Current (ACC). The ocean-atmosphere coupling occurs through surface heat fluxes and Ekman cur- rent heat advection. In a fully coupled simulation, the atmos- pheric part of the model, which includes high frequency tran- sient eddies at midlatitudes, exhibits a strong Southern Annu- lar Mode (SAM) as the first mode of variability...
