The sea surface temperature (SST) in the equatorial Atlantic has variability over the years with many interacting processes in the region that is influenced by the dynamics of winds, currents, tides and discharge of the Amazon River. The present study is an analysis of SST near the northern coastal region, using AVHRR sensor monthly data aboard the NOAA satellite for the period of January 1998 to December 2007. It was possible to avaliate through this time series the SST behavior in space and time with an objective description of the images and quantify the time-scale variability by wavelets transformed. It was also analysed the correlations of SST data with OLR (Outgoing Longwave Radiation) and the flow of the Óbidos station to represent the Amazon River flow, in order to understand the processes that are related. The correlation between SST and OLR weren´t significant for the study period, the correlation between SST and low flow, indicating that the flow is not a dominant factor for the variability of SST of the northern waters of Brazil. The correlation between the SST anomalies for the three points, and the SST anomalies in the basin of the North and South Atlantic have clearly shown the influence of the dipole in the study area, suggesting that they are strongly associated.Pages: -781
