                         the annual number of thunderstorm days (TD) of Rio de Janeiro from 
                         1951 to 2009 is related to any large scale weather phenomena. 
                         Wavelet, cross-wavelet and wavelet coherence analyses, as well as 
                         associated statistical significance tests, were used to 
                         investigate the frequency structure of TD as well as the Tropical 
                         Southern Atlantic Index (TSA), Southern Oscillation Index (SOI), 
                         the Pacific decadal oscillation (PDO) and the International 
                         Sunspot Number (ISN). Wavelet analyses indicated that the 
                         variability of Rio de Janeiros TD can be primarily explained by 
                         two distinct significant (p<0.05) peaks of periodicity of 1 year 
                         and 12 years. The 1 year periodicity in TD is well established, 
                         being associated to the difference in temperature from summer to 
                         winter. Our results suggest that the 12 years periodicity in TD is 
                         mainly caused by fluctuations in the TSA. The cross-wavelet 
                         spectrum of the TD and TSA indicated a significant peak at 12 
                         years. Furthermore, wavelet coherence demonstrated that the 
                         intensity of the 12 years periodicity of the TD and TSA were 
                         significantly positively correlated through time. The study 
                         concludes that TSA contributes significantly to the variability of 
                         the TD in Rio de Janeiro indicating it may be potentially used in 
                         TD forecasting.",
