| prevailing westerlies | strong steady winds blowing from high pressure area in horse latitude towards the poles |
| polar easterlies | often very weak and irregular, cold winds that can cause weather changes in the US |
| jet stream | narrow belt of strong, high speed winds, high pressure air flowing west to east |
