RESUMO
Climate variability is a complex system generated by the participation of various actors and their role in atmospheric dynamics, the Sea Surface Temperature(SST) plays a key role in influencing the several features of the climate indexes: Southern Hemisphere Cancel Index Mode (SAM), Southern Oscillation Index (SOI), El Nino / Southern Oscillation (ENSO), (TNA) Tropical North Atlantic Index (PDO) Pacific Decade Oscillation, North Atlantic Oscillation Index (NAO). The climate changes indexes and their implications have a spectrum in the activity and formation of the climate, which begins in macro-systems through their extraterrestrial influences, during periods of solar activity and others, who urges us to search a better understanding of the climate and its resultant forces. Therefore, this is a simplistic research, seeking to show the entities involved in the climate variability processes, emphasizing much more the role of the oceans and its influence on the fluvial routines correlation, and estimating also define a major and also a better understanding of the hydrological cycle spatiotemporal scale in the region of the Amazon basin, starting from a reading of the atmospheric system and its resulting dynamic influence on the hydrological cycle, acquired through this research (ANA) National Water Agency data flow of the rivers Solimões / Amazonas and Negro River, and with the Earth System Research Laboratory - Physical Sciences Division of NOAA, which acquired values of SST and climate indexes. The precipitation data was requested from Center for Weather Forecasting and Climate Studies (CPTEC / INPE). All these data were processed in the processing software GrADS and also compiled in FORTRAN for statistical analysis using (R) - Analysis and Design of Experiments, to provide data for linear correlation, T-test and linear regression in order to sustain and support the analysis of the results which could predict from the discrepancy between the SST variables and the resulting conduct of river flow.
