| Abstract | An analysis of decadal and long-term pattems of rainfall has been carried out using a combination of .raing-gauge and gridded rinfall data sets, for the entire Amazon basin and for its northern and southern sub basins. The study covers 1929-98, but more detailed anaiyses were performed during 1950-98 regarding rainfall variability and variations in circulation and sea surrare temperature fields. Negative rainfall trends were identified for the entire Amazonia, while at regional levels there is a negative trend in northern Amazonia and positive trend in southern Amazonia. Perhaps, the most important aspects of this work is the identification of decadal time scale variations in rainfall in Amazonia, with periods of relatively drier and wetter conditions, which are contrasting for northern and southern Amazonia. Spectral analyses show decadal time scales variations in southern Amazonia, while northem Amazonia exhibits both interannual and decadal scale variations. Shifts on the rainfall regime in both sections ofthe Amazon basin were identified in middle 1940's and 1970's. After 1975-76, northern Amazonia exhibited less rainfall than before 1975. Changes in the circulation and oceanic fields after 1975 suggest an important role of the warming of the tropical central and eastern Pacific on the decreasing rainfall in northern Amazonia, due to more frequent/intense strong El Nifio events during the relativeiy dry period 1975-98. |
