Perhaps decoupled isn't the right word. I also used 'different'.

Given the pushback, I'll not watch it again, but there was discussion of the Coriollis Effect. The trade winds create three zones. Does that work?

It's an artifact of latitudinal velocity around Earth's spin axis.
At the Equator, the ground underfoot is moving with a velocity of 1,032-mph at that average mean radius from Earth's center.
It's zero at the poles.
The further you move north, or south of the Equator, the 'slower' the velocity.
It's what explains the direction a whirlpool forming in a sink or bathtub exhibits. They're 'opposite' depending on which 'hemisphere' you're in.
( computer-generated military sniper firing solutions for their Barret 0.50 long guns must incorporate the 'Coriolis Effect' in order to compensate for their target, that may be a mile away in latitude )
Fluids ( air and water ) on Earth's surface ARE affected by the effect, but there are a lot of other dynamics also influencing 'local' phenomena. This is where Lindzen went off the rails.
As he's a 'meteorologist ( a very good one on all accounts ), and not a 'climatologist', he would not have the specialized knowledge of those who pushed back against his 'childlike' global warming hypothesis ( he just didn't know what he didn't know ).

Of course I know what the Coriolis Effect is (even if I can't spell it corectly). I was wondering how Hadley Cells differentiate the regions rather than diffusing them.

Hadley cell
The Hadley cell, also known as the Hadley circulation, is a global-scale tropical atmospheric circulation that features air rising near the equator, flowing poleward near the tropopause at a height of 12–15 km above the Earth's surface, cooling and descending in the subtropics at around 25 degrees latitude, and then returning equatorward near the surface.

...there are a lot of other dynamics also influencing 'local' phenomena.

This is the part I was concerned with.

What part of 'expert' are people not getting?

This is the part I was concerned with.

The moist equatorial heat creates the convective available potential energy ( CAPE ) which causes the vertical movement up to the 'top' of the 'climate', which 'decompresses' it as it moves higher into more, less-dense, rarified air, where it loses heat of compression ( exactly as in a refrigeration cycle ), then falls northwards, where it's cooler/denser mass causes it to descend, traveling back to its origin.
There's something specific about the 'conditions' around 25-degrees, N-S latitudes that constrain the circulation ( El Nino, La Nina, Rossby waves, sea surface temperatures, ocean currents, island archipelagos, ocean gyres, wind, whitecaps, marine cloud layer, stratospheric clouds, atmospheric aerosols, Saharan dust, contrails, coldwater upwellings, submarine thermohaline cycle, seasonal land-based vegetative cover dynamics, diurnal effects, seasonal solar insolation variability, ocean mid-depth dynamics, sea floor dynamics, sea floor topography ( volcanic sea mounts, rift valleys, canyons, tectonic spreading, etc. ), etc..

That's the only part that advances the conversation. First paragraph is a redefinition of Coriolis Effect, the rest is word salad. I did have to look up Rossby waves. So there is that.
