             abstract = "For four locations (Samuel, 9° S, 63° W; Balbina, 1° S, 59° W; 
                         Curua-Una, 13° S, 54° W; Tucurui, 4° S, 50° W) in the Amazon, the 
                         river stream-flows (RSF) were maximum during March, April and/or 
                         May and minimum during September-October, while rainfalls in 
                         similar areas had maximum earlier, in January-March. There were 
                         considerable year-to-year fluctuations, not always similar at all 
                         the locations. An examination of the two largest El Niņo events 
                         (1982-83 and 1997-98) showed some effects at some locations during 
                         intervals when the El Niņos were active, but some effects were 
                         seen even outside these active intervals. Some RSFs showed 
                         relationship with South Atlantic SST. A spectral analysis showed 
                         that ENSO indices had prominent periodicities at 7-9, ~6 years and 
                         QTO (Quasi-triennial oscillation, 3-4 years) and not so prominent 
                         periodicities in the QBO (Quasi-biennial oscillation, 2-3 years). 
                         These were only partially reflected in some RSFs. There is an 
                         indication that some hydrological QBOs may be related to 
                         stratospheric wind QBO. Besides QBO and QTO, the RSFs had 
                         significant periodicities in 7-14 years range, ~22 years and ~55 
                         years. Long-term trends (23-year running means) were not linear 
                         and showed oscillations of ~0.2%, grossly dissimilar at the 
                         different locations.",
