@StefJamieSan @Petergrmathews @tim_dunkerton Number one rule: don't listen to loud atmospheric physicists such as Dunkerton. They tend to mess things up

@StefJamieSan @Petergrmathews @tim_dunkerton Too much fun, winning is not boring at all.

Improved over Lindzen, yet not even close to admitting that lunar cycles w/annual drive the EXACT synching of QBO. And that's what's important for predictions.

@StefJamieSan @Petergrmathews @tim_dunkerton Doesn't matter, as doubling down on an incorrect model just exposes its faults. A better model should explain the anomalous points as well.

@StefJamieSan @Petergrmathews @tim_dunkerton No one complains about the overfitting performed for next week's solar eclipse. It's whether it works or not.

@StefJamieSan @Petergrmathews @tim_dunkerton Only the draconic cycles impact a wavenumber=0 behavior, and those cycles don't impact LOD. Yes, they impact Chandler wobble. This is masterful geophysics described on the recent blog post:

@StefJamieSan @Petergrmathews @tim_dunkerton Doesn't seem to understand that LOD is a solid body response, not a fluid. The solid body is not uniform, featuring continents & mountain ranges, providing spatially resolved moments of inertia for the lunar gravity to torque on. Let ChatGPT teach you:

@StefJamieSan @Petergrmathews @tim_dunkerton He complains when he isn't precise enough. Solid body is different than solid body response.

@StefJamieSan @Petergrmathews @tim_dunkerton So now he wants to know how to solve Laplace's Tidal Equations on an equatorial waveguide, where the Coriolis force vanishes. The interface properties of a topological insulator emerge -- ask Marston of APS about the viability of such a behavior

@StefJamieSan @Petergrmathews @tim_dunkerton Hough functions are simply dispersion relationships on a sphere -- they've nothing to do with what gets selected. A wave incident at a right angle to the equator will generate an infinite phase speed wave along the waveguide, much like a boundary Kelvin wave along a shoreline.

@StefJamieSan @Petergrmathews @tim_dunkerton Now the connection to a solid body response. Solid is rigid so torque at any longitude will ripple through as a wavenumber=0. However, for a compressible fluid like air, every longitudinal line must act in UNISON for a WN=0, thus the nodal alignment independent of longitude.

@StefJamieSan @Petergrmathews @tim_dunkerton As I said, only a nodal wave such as the semiannual solar crossing or the draconic/nodal lunar crossing can generate a UNIFORM shear stress across the equatorial plane. If SAO sets the behavior, then the QBO must also exist for lunar forcing. No moon, then no QBO, only SAO.

@StefJamieSan @Petergrmathews @tim_dunkerton No controlled experiment to validate any of this Dunkerton spew. Instead, as Lindzen said, the onus is on the reviewing team to demonstrate that a draconic period of 27.2122 days CAN'T support the QBO cycle. Should be simple for you to debunk, after all it's just arithmetic ;)

@StefJamieSan @Petergrmathews @tim_dunkerton Yes, I don't claim that as a discovery, but Dunkerton has now admitted that long period nodal forces drive these oscillations. Seasonal nodal for SAO and lunar nodal for QBO. No going back at this point.
