Recent studies suggest that interannual, decadal and quasibidecadal periodicities dominate global sea surface temperature and sea level pressure variability over past hundred years. In this study, we present evidence that the quasibidecadal mode of variability can be considered in a first order approximation as resulting from a linear combination between the dominant modes of variability in the Tropical Pacific (associated with interannual variability). A two coupled delayed action oscillators model is proposed to qualitatively explain this result.
