- W2077497986 abstract "Southwest of Portugal, in situ data show that part of the mesoscale variability of the Mediterranean Water undercurrents is triggered by topographic effects (near capes and submarine canyons), and is driven by a dominantly baroclinic instability. The vertical alignment of these undercurrents observed at sites of eddy formation is indeed favorable to baroclinic instability. This instability is materialized by the formation of filaments and of small eddies in the Portimão canyon and of meddies near Cape Saint Vincent and near the Estramadura Promontory. Hydrological data and float trajectories reveal that these eddies have a baroclinic structure. Near Portimão canyon, the variation of the potential vorticity of the undercurrents again proves their sensitivity to baroclinic and also to barotropic instabilities, enhanced by the canyon. Finally, a model of stationary coastal current explains the variations of its horizontal structure over a canyon. Instabilité des sous-courants d'eau méditerranéenne au sud-ouest du Portugal : effets conjoints de la baroclinicité et de la topographie. Au sud-ouest du Portugal, des données in situ montrent qu'une partie de la variabilité méso-échelle des sous-courants d'eau méditerranéenne est déclenchée par des effets topographiques au voisinage des caps et des canyons sous-marins et est générée par une instabilité essentiellement barocline. L'alignement vertical de ces sous-courants, observé aux sites de formation de tourbillons, est en effet favorable à l'instabilité barocline. Cette instabilité est matérialisée par la formation de filaments et de petits tourbillons lenticulaires dans le canyon de Portimão, et de “meddies” au cap Saint Vincent et près du promontoire d'Estrémadure. Les données hydrologiques et les trajectoires de flotteurs lagrangiens révèlent que ces tourbillons ont une structure barocline. Près du canyon de Portimão, la variation de la vorticité potentielle des sous-courants montre leur sensibilité à l'instabilité barocline, et également barotrope, amplifiées par le canyon. Enfin, un modèle de courant côtier stationnaire permet d'expliquer ses variations de structure horizontale sur un canyon." @default.
