                         and decadal time scales on the water balance of the Amazon basin. 
                         This research is interesting because it brings the dynamical 
                         response of water balance components to a particular ocean-scale 
                         variability. For this, we used the Brazilian Global Atmospheric 
                         Model (BAM) and SST filtering techniques. The impact of isolated 
                         interannual and decadal time scales was quantified for episodes of 
                         ENSO and the Atlantic dipole (AD). The results show that isolated 
                         interannual scales weaken the impacts of El Nino and La Nina on 
                         water balance components in the northern Amazon and northeastern 
                         Brazil. Such weakening is more evident in episodes of El Nino than 
                         in those of La Nifia. This indicates that El Nino is more 
                         dependent on other time scales (in addition to interannual) than 
                         is La Nina. In relation to the Atlantic, a positive AD increases 
                         (decreases) precipitation in the northern (southern) Amazon basin 
                         in the experiment with all SST time scale variabilities. On the 
                         other hand, when the decadal scale is isolated, an increase in 
                         precipitation in the northern basin is not observed, losing the 
                         dipole pattern in the precipitation anomaly between the northern 
                         and southern Amazon basin. BAM is not sensitive to a negative AD 
                         when SST is isolated in the decadal scale. These results are 
                         important for monitoring the climate of humid tropical regions, 
                         mainly for the study of ENSO, since, according to recent research, 
                         these extreme events will be increasingly frequent and intense.",
