PaulP:"There is no cross-talk. There is only a common-mode forcing."
Thanks; you assert that there is no direct Lunisolar effect on ENSO-QBO sensor data, so you deny any "crosstalk noise" in the data, which you believe only contains pure Lunisolar Forcing signal.
Lets be clear what the "common-mode" channels are that you refer to in ENSO-QBO measurement. The primary channels are the embodied Geophysical Oscillations. Secondary channels are the multi-sensing data buoys, sonde, satellites, whatever. Lunisolar input is the common-mode forcing on all these channels. We agree, for example, that the lunar tide perturbs sea-buoys by directly affecting the sea-state.
We agree on Lunisolar Forcing in general, just disagree on how strong the forcing is and whether there are other forcing factors, or "only" one. Direct Lunisolar forcing of the multi-sensing data is not what the sensors are trying to measure, instead trying to measure ENSO-QBO state, but they do measure the three-body orbital state as well. There is always >0 crosstalk in closely run channels. I take your meaning to be, "no (significant) cross-talk".
Here is a Gedanken-
If the Earth were blanketed with an opaque atmosphere, sea-buoy and sonde arrays would nevertheless faithfully encode an "data animation" of the positions of Sun, Moon, and Earth rotation phase.
You claim no such data is overlaid on ENSO-QBO data ("no cross-talk"), only forcing signal.
