                         ABSTRACT: The atmosphere is a complex system, which presents 
                         interactions at different temporal and spatial scales. Many 
                         studies have already been made in order to relate events occurring 
                         in different localities of globe and, nevertheless, are 
                         correlated. This study intends to analyze,using cross­wavelets 
                         techniques, the possible relationship between the Quasi­Biennial 
                         Oscillation (QBO) and the Antarctic Oscillation (AAO), since 
                         similar relationship has already been investigated for Northern 
                         Hemisphere (NH), between QBO and Arctic Oscillation (AO; NH 
                         counterpart of AAO). The results of cross­wavelets between QBO and 
                         AAO indices showed a peak of energy in the 2­year period, with a 
                         time lag that varies according to analyzed period.",
