In addition to applying the modeling steps to ENSO, we can apply the same procedure to QBO. This is more straightforward because the arcsin transformation for QBO is very mild in comparison to ENSO,


The general wavelet scalogram patterns are very similar to ENSO. The distinction is that the QBO model uses a Draconic factor as the fundamental forcing (since the standing wave is longitudinally symmetric) while ENSO uses Synodic (as the forcing is strongest in the Pacific). Also QBO is forced semiannually, as can be guessed from the Semi-annual Oscillation that exists at higher altitudes than QBO, while ENSO is forced annually.
