Global Wind Belts

How Earth's global wind belts form

There is always some confusion about how the winds can be deflected in different directions. It is because the wind gets deflected from the direction it is traveling. Imagine you are walking along that arrow between 30*N and 60*N from the south to the north. The Coriolis will deflect you to the right of that direction, and your resulting direction will be to the east. The same thing if you are walking between 0* and 30* only now you are walking north to south. If you get deflected to the right, your resulting direction is to the east.

Also, I keep meaning to go back and edit this, but only the circulation cells between 0* and 30* are called Hadley cells. Between 30* and 60* they are called Ferrell cells, and between 60* and 90* they are the polar cells.
