                         surface temperature (SST) indices in selected oceanic sectors are 
                         documented using correlation analyses. For the total correlation 
                         between the eastern equatorial Pacific (EEP) and tropical South 
                         Atlantic (TSA) indices and the precipitation, the differences 
                         between the two periods reflect, in part, the El Niņo-Southern 
                         Oscillation (ENSO) teleconnections over South America, with the 
                         Pacific decadal oscillation (PDO) background acting to enhance 
                         (weaken) the correlations when ENSO and PDO are in the same 
                         (opposite) phase. For the total correlation between the tropical 
                         North Atlantic (TNA) and southwest South Atlantic (SWA) indices 
                         and precipitation, the results here suggest that the differences 
                         between the two periods might be reflected as variations in the 
                         Bolivian high-pressure system. Both the TNA and TSA indices may 
                         act to weaken the positive ENSO relations with precipitation over 
                         central and eastern Brazil during the cold PDO phase. These 
                         analyses provide indications that the ENSO relationship with the 
                         TSA shows differences between the two analysed periods.",
