28. If Earth and its atmosphere were spinning eastwards over 1000 mph clouds could not be travelling casually in different directions
“If Earth and its atmosphere were constantly spinning Eastwards over 1000 mph then clouds, wind and weather patterns could not casually and unpredictably go every which way, with clouds often travelling in different directions at different.”
Dubay does not understand that winds are relative to the moving atmosphere
The atmosphere spinning eastwards at over 1000 mph (at the equator) causes no wind. We would experience that as a perfectly still day because we would also be moving eastwards at over 1000 mph standing on the spinning earth.
What we experience as winds are air movements relative to that eastward movement caused by the spin of the earth.
E.g. If we were standing near the equator and the atmosphere surrounding us was rotating with the Earth at 1200 mph eastward we would experience that as a 200 mph eastward wind.
If atmosphere surrounding us was rotating with the Earth at 800 mph eastward we would experience that as a 200 mph westward wind.
Of course the atmosphere is very turbulent. Hot air rises and cold air falls. The atmosphere at the equator is hotter than at the poles which sets up currents between the equator and the poles.
The Coriolis effect causes eastward currents north of the equator and westward currents south of the equator. There are also circular patterns caused by hurricanes and tornados.
We experience this turbulence as winds in different directions at different latitudes and altitudes but all of these movements are relative to the atmosphere which is moving with the Earth.
So … it makes perfect sense for us to experience winds in all directions on a spinning earth, and of course clouds travel in the same direction as the winds.
