Identification ofthe low-frequency variability in some coastal stations of the southeast coast of Brazil

In this study time series of marine surface parameters for 35 years along the south east coast of Brazil, in particular for the regions of Cananéia and Ubatuba are examined. The goal was to look for regional cIimate indications of global cIimate impacts in the low-frequency range of the spectrum in phenomena such as ENSO (EI Nifio - Southem Oscillation) and the Atlantic ocean dipole. It was fOUQd that ENSO has a direct impact over the time series along the coast but does not determine then. The Atlantic dipole has little impact on the SE coast of Brazil. In the NE region, its impact on $e decadal time scale is significant.
