Eli5 Where do wind/gale originate? Do Newton’s 3rd law and laws of energy apply on winds

In: 5

Answer 1

Newton’s laws do indeed apply to wind.
The main sources of wind are the rotation of the Earth and the fact hot air rises/cold air sinks.
The main cause of air being hot or cold is the sun heating it near the equator or polar air not getting solar heat.
At the Equator the Earth is rotating at the speed of 24000ish miles per day (1000mph) and the air is similarly accelerated, but near the poles the Earth is narrower and rotates slower and has slower moving air.
The combination of rotational and temperature differences create “Hadley cells” which drive most weather.
At a smaller scale land heats and cools more quickly than the Ocean does and continents sucks in air from the sea in the summer and blow air out to sea in the winter.
