Última Mesoscale SST–wind stress coupling in the Peru–Chile current system: Which mechanisms drive its seasonal variability? ArchiMer Oerder, Vera; Colas, François; Echevin, Vincent; Masson, Sebastien; Hourdin, Christophe; Jullien, Swen; Madec, Gurvan; Lemarie, Florian. Satellite observations and a high-resolution regional ocean–atmosphere coupled model are used to study the air/sea interactions at the oceanic mesoscale in the Peru–Chile upwelling current system. Coupling between mesoscale sea surface temperature (SST) and wind stress (WS) intensity is evidenced and characterized by correlations and regression coefficients. Both the model and the observations display similar spatial and seasonal variability of the coupling characteristics that are stronger off Peru than off Northern Chile, in relation with stronger wind mean speed and steadiness. The coupling is also more intense during winter than during summer in both regions. It is shown that WS intensity anomalies due to SST anomalies are mainly forced by mixing...

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...
