ENSO is measured many ways; including current, wind, atmospheric-pressure, sea-surface height, and sea and air temperature. Lunisolar tidal noise is predicted here in all of these data sets, as well as weak long-period harmonic forcings buried in the chaos. Its not all noise nor all signal. Its a ratio to properly quantify.
Again, Jupiter QQO strongly suggests Earth QBO would blow even if there was no Moon. Its not the Moon that drives QBO, but mostly Vertical Coriolis with an aeroelastic spring-mass dynamic (clock balance-wheel analogy). Atmospheric Tides therefore modulate QBO velocity a bit, and thus Lunisolar noise shows up in real-time QBO sonde data.
That's several predictions for geoscience to confirm or falsify.
