                         The main objective of the present work was to investigate the 
                         relative importance of the tropical and southern subtropical 
                         sectors of the Atlantic and the eastern equatorial and southern 
                         subtropical sectors of the Pacific in the interannual 
                         precipitation variability taking into account the Pacific decadal 
                         oscillation (PDO) phases. Monthly precipitation and sea surface 
                         temperature (SST) data were used. The SST indices were obtained 
                         for selected oceanic sectors (eastern equatorial Pacific - EEP, 
                         southeastern subtropical Pacific - SSP, tropical North Atlantic 
                         -TNA, tropical South Atlantic -TSA and subtropical south Atlantic 
                         - SSA). The wavelet transform technique was used to identify the 
                         dominant scales of the SST indices during the 1948-2002 period, as 
                         well as to filter the data for the interannual scale. Analyses are 
                         based on correlation maps, which were obtained from simultaneous 
                         and lagged and total and partial correlation calculations. The 
                         analyses showed that the two Pacific sectors have inversed 
                         relationships with the precipitation. For the Atlantic sectors, 
                         the TNA almost does not have influence on the precipitation, while 
                         the TSA and SSA affect considerably the precipitation of distinct 
                         areas of South America. The analyses showed also differences 
                         between the two phases of the PDO in the relations of the SST 
                         indices and the precipitation over South America.",
