Wind

The wind is caused by the rotation of the Earth and uneven heating from the sun. The following video explains the creation of wind and why it doesn't flow in a straight path.


Earth has 3 major global wind systems:
  1. Polar Easterlies
  2. Westerlies
  3. Trade Winds
Each wind zone is deflected from its straight path due to Earth's rotation, which creates the Coriolis Effect. The Coriolis Effect causes wind (and ocean) currents to be deflected to the right in the northern hemisphere and to the left in the southern hemisphere.
