                         (NEB) rainfall to the sea surface temperature (SST) in the 
                         60šN-30šS ocenaic sector and to the global sea level pressure 
                         (SLP) anomalies are investigated for the 1871-1991 period. Indices 
                         are defined for the precipitation and for the SST anomalies in the 
                         tropical North Atlantic (TNA), in the tropical South Atlantic 
                         (TSA), and in the eastern equatorial Pacific (T-TNA, T-TSA, and 
                         T-NINO indices, respectively). An index is also defined for the 
                         SLP anomalies in the North Atlantic Ascilation region (P-NAO 
                         index). These indices and the SST and SLP anomaly time series are 
                         filtered for the decdal scale using the continuous wavelet 
                         transform. The filtered time series are then subjected to the 
                         correaltion and partial correalation analyses. The results 
                         indicate that the decadal variations of the northern NEB rainfall 
                         might be independently linked to the Pacific Decadal Oscillation 
                         (PDO)/NAO/TNA decadal realtions or the SST decadal variations in 
                         the TSA. This is a new result not discussed before. The northern 
                         NEB rainfall linkage to the PDO/NAO/TNA relations is indicative 
                         that the relationship of the SLP variations in the NAO region and 
                         the NEB rainfall proposed in a work during the 1970s is part of 
                         the decadal climate variability that connects the PDO in the 
                         tropical Pacific to the NEB rainfall through the Northern 
                         Hemisphere extratropical atmosphere.",
