Wind is solar energy, it's the product of the sun heating air.


A very small percentage of the wind on the planet is a "product of the
sun heating air".


In that case you'll now post what causes the rest??? Even the migration
of the various entire systems from the west to the east is directly
related to the sun.

Anyway if you think otherwise I for one will read your explanation with
interest.

Sure thing, ask and you shall receive. That above statement about
migration of various entire systems is pure rubbish. Ever hear of the
Coriolis Force? Guess not, huh? Anyway: Wind is the product of the
movement of air. Air has a certain density and surrounds the earth for
a layer of approximately 64km in altitude. Air exerts a downward
pressure, which is referred to as atmospheric pressure. The pressure
on the earth's surface is one atmosphere, or one "bar", at sea level
(mean absolute sea level/masl). Air pressure is measured with a
barometer.


As the Earth rotates on its axis, gravity forces this relatively
"heavy" air near the Earth's surface to spin round with it. However,
the air higher up is less affected. The difference between the speed
at which air moves close to the surface and the speed of air higher up
forms vortexes or whirlpools. This mixing causes variations in air
speed, and, consequently, "wind" is generated at the earth's surface
