Could somebody please offer a simplified arial view depiction / description of how wind works. I need to explain to somebody "where gusts go".

Can anybody simplify that? Who was it who said.."If you cannot explain it to a 12 year old then you dont know it yet" etc... That sort of vein.
1) The earth spins, and all the "rough edges" of mountains and valleys drags the air around.

2) Heating & cooling from the sun and day/night cycles causes warm air to rise and cool air to sink. Air has to move sideways to replace the air that moves vertically.

3) Butterflies, birds, people, and airplanes move the air, as well as fans, air conditioners, factories, and boats.

4) The drag of trees, buildings, mountains, and air against itself slows down the wind, dissipating the gusts.

Multiply all that by a gazillion permutations, and you get the winds we feel!
