Hi B/C in regards to the effects being small, I assume you are referring to the positive/negative frictional coupling Effect between the Atmosphere and earth’s surface, as per the original question.So just to put a comparison value to reiterate that point and I think you posted previously in regards to how large the earth’s angular momentum is.As a fraction of the Total solar radiation Received by Earth for one day allowing around 30% reflection vs Earth’s rotational Kinect energy gives :Solar energy per day is 0.000005% of Earths rotational Kinect energy
And what Alan was saying was that the spin of the Earth powered the weather.
I never said that.
Ignoring second-order effects such as thermal winds, the source of kinetic energy is the rotational energy of the planet, so it must eventually stop spinning.
The prevailing geostrophic wind is the result of coriolis force making the air move relative to the surface of the earth. If we extract kinetic energy from the geostrophic wind and dissipate it as heat, whence came that energy? The only source is the spin of the earth.
The wind in the Southern Ocean is almost entirely due to the earth's spin
Blazing sunshine today, no wind. If the sun powers the wind, why not?
Was it some other Alan Calverd then?
Just stop being silly and admit you got it utterly wrong.

This isn't new stuff.
The geostrophic wind is crucial to understanding major weather systems.
I refer the hon gent to reply #8 above
