Ipso facto, it is incapable of
producing multidecadal oscillations that are not there in the record.
sky, How can you say «
producing multidecadal oscillations upon integration is mathematically impossible» when the integration is clearly showing multidecadal oscillations?
The entire idea of higher - frequency components (the power spectrum of the Nino3.4 record peaks at ~ 5.5 a periods)
producing multidecadal oscillations upon integration is mathematically impossible.
