However, your assertion that there would some sort of wind shear going north (or south) from the equator is a fallacy.
Assuming none of the air moves ever and every atom stays exactly where it is, as though it were a solid ... you'd still be wrong. We see shear forces even in the solid and liquid of a round earth. This is why the earth bulges at the equator according to RE.
If the air moves North or South, that air has mass. And you need to apply a force to either speed it up or slow it down. This as mentioned is just simple Newtonian physics.
Speed does not require power when there is no friction. Acceleration requires power.
Correct, which is why if you accelerate or decelerate the average speed of air as it moves North or South (and it will because of Coriolis, even if you exclude the Hadley Cell effect and trade winds due to continental/ocean temperature differences) you have a rate of change. And rates of change require power (Newton).
I get it. Air is hard to imagine. It is invisible. But its turbulent and is moves over and over itself as it spins with earth. Maybe this will help you visualise rotating air moving around itself in a chaos type format.
Now the real reason is
https://en.wikipedia.org/wiki/Wind_shearAnd this occurs
because earth spins *hint: you don't want to deny this, you want to accept and prove it if the earth is to be round*. I don't mind if you round earthers get the shape of earth wrong, but make sure you understand how
your theory works at least.
Without accepting wind sheer caused by spin, you blow away a huge ROUND earth proof. Not that in 10 years anyone has ever brought this up ... but hey, I'm not on your side.
Wind changes direction with altitude ... and it tends to 'back' in the Northern hemisphere (anti-clockwise) and 'veer' in the Southern hemisphere (clockwise).
This is known to all pilots around the world. It helps you guess the wind direction at certain altitudes if you don't have the data.
Please read the short piece on geostrophic and cyclostrophic winds below. Note the friction mentioned (ie gonna get static build up).
https://www.recreationalflying.com/tutorials/meteorology/section6.htmlNote also the effect of friction on the surface of the earth (setion 6.2). Yes, you keep denying such a thing exists. Like we are in some kind of perpetual motion machine. The air will act like a giant brake on the earth as mentioned before.
If you want proof here is someone testing that theory in an aircraft.
Some basics about wind here.
VEERING AND BACKING
The wind veers when it changes direction clockwise. Example: The surface wind is blowing from 270°. At 2000 feet it is blowing from 280°. It has changed in a right-hand, or clockwise, direction.
The wind backs when it changes direction anti-clockwise. Example: The wind direction at 2000 feet is 090° and at 3000 feet is 085°. It is changing in a left-hand, or anti-clockwise, direction.
In a descent from several thousand feet above the ground to ground level, the wind will usually be found to back and also decrease in velocity, as the effect of surface friction becomes apparent. In a climb from the surface to several thousand feet AGL, the wind will veer and increase.
So ... once you learn about weather properly, I want to know a) why the earth hasn't come to a stop with all this surface friction slowing it down b) why I'm not being hit by lightning bolts every 3 seconds with all this static build up. You will have to learn more than I have shown you to answer those questions ... and we can all assume the earth is flat until you do.
