abstract = "The influence of the large-scale climatic variability dominant
modes in the Pa- cific and in the Atlantic on Amazonian rainfall
is investigated. The composite technique of thc Amazon
precipitation anomalies is used in this work. The basis years for
these composites are those in the period 1960-1998 with
occurrenccs of cxtrcmes in thc Southern Oscillation (El Nino or La
Nina) and thc north/south warm (or cold) sea surface temperature
(SST) anomalies dipole pattem in the tropical Atlantic. Warm
(cold) dipole means positive (negative) anomalies in the tropicai
North Atlantic and negative (positive) anomalies in the tropical
South Atlantic. Austral summer and autumn composites for extremes
in the Southem Oscillation (El Nino or La Nina) and independently
for north/south dipole pattem (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 si- multaneous occurrences of El
Nino and warm north/south dipole of the SST anomalies in the
tropical Atlantic show negative precipitation anomalies extending
eastward over the center-east- em Amazon. This result indicates
the important role played by the tropical Atlantic in the Ama- zon
anomalous rainfall distribution.",
