    There is no real snchronization between the QBO and ENSO since QBO has a wavenumber of 0 implying only tidal forces of hemispherical symmetry will be involved, such as the lunar and solar nodal tide. On the other hand, since ENSO is a tropical Pacific with non-zero longitudinal wavenumber, the lunar tropical/synodic tide provides the greater forcing.
