Abstract: Internal ocean processes, dynamically induced, cause high sea surface temperature gradients and surface heat fluxes. The correlation and the covariance between temperature and heat fluxes can be used to distinguish sources of variability allowing to define an ocean and an atmosphere driven regime. Here we introduce this method using observational data with different resolutions to distinguish different regimes of variability and to investigate spatial resolution effects. We focused over the Agulhas Current region and the Eastern South Atlantic, where waters flowing following the African coastlines in the Indian Ocean generate turbulence. Such mesoscale activity can lead to the detection of the ocean-driven regime. The increase of resolution gives a better representation of the cross-covariance patterns, indicating an improvement on the detection of eddies.
