Question

Eli5: Why does weather generally move west to east

In: Planetary Science

Answer 1

**prevailing winds** moves moisture and varying temperature air.

warm pacific ocean air moves over colder mountains, then dryer deserts, then mixes with warmer wet air from gulf or cold wet air from great lakes. every time there is a mixture of hot/cold cold/hot wet/dry dry/wet there is a chance of changing weather

and as to why the prevaling winds just happen to move west to east – rotation of the earth
