                         Short-interannual to decadal variability of the Tropical Atlantic 
                         (TA) sea surface temperature (SST) is studied using the Continuous 
                         Wavelet Transform (CWT). This technique is applied on the SST 
                         indices in the Tropical North Atlantic (TNA) and in the Tropical 
                         South Atlantic (TSA) and on the difference between the TNA and TSA 
                         indices (TNSD). The decadal peaks are dominant for the TNA and TSA 
                         indices. The fact that the significant decadal variances of the 
                         TNSD index, in general, have correspondence to the significant 
                         variances of either the TNA index or TSA index, confirms the 
                         independence of the decadal SST variability in the two sides of 
                         the TA. Exception to this is noted during 1970-1985 when 
                         significant decadal variances occur for the TNA and TSA indices. 
                         Nevertheless, the simultaneous occurrences of significant 
                         variances for the TNSD, TNA and TSA indices not necessarily imply 
                         in the establishment of a dipole-like pattern or in the dynamical 
                         connections between the TNA and TSA. The SST propagation features 
                         are similar to those described previously for the SST anomalies in 
                         the TA for the short-interannual and decadal scales.",
