                         climatic variability dominant modes in the Pacific and in the 
                         Atlantic on Amazonian rainfall is investigated. The composite 
                         technique of the Amazon precipitation anomalies is used in this 
                         work. The basis years for these composites are those in the period 
                         1960-1998 with occurrences of extremes in the Southern Oscillation 
                         (El Niņo or La Niņa) and the north/south warm (or cold) sea 
                         surface temperature (SST) anomalies dipole pattern in the tropical 
                         Atlantic. Warm (cold) dipole means positive (negative) anomalies 
                         in the tropical North Atlantic and negative (positive) anomalies 
                         in the tropical South Atlantic. Austral summer and autumn 
                         composites for extremes in the Southern Oscillation (El Niņo or La 
                         Niņa) and independently for north/south dipole pattern (warm or 
                         cold) of the SST anomalies in the tropical Atlantic present values 
                         (magnitude and sign) consistent with those found in previous works 
                         on the relationship between Amazon rainfall variations and the SST 
                         anomalies in the tropical Pacific and Atlantic. However, austral 
                         summer and autumn composites for the years with simultaneous 
                         occurrences of El Niņo and warm north/south dipole of the SST 
                         anomalies in the tropical Atlantic show negative precipitation 
                         anomalies extending eastward over the center-eastern Amazon. This 
                         result indicates the important role played by the tropical 
                         Atalntic in the Amazon anomalous rainfall distribution.",
