Global Winds
By Brett Dubuque, Daniel Curtis, and Brittany Farnsworth

2. Global Winds caused by unequal heating on earth’s surface
Giant convection currents move air all over the world

3. The Coriolis Effect Global winds move from the poles to equator
Earth’s rotation makes winds curve

4. Global Wind Belts
Trade winds, Polar easterlies, and Prevailing westerlies are the major global wind belts.
Caused by convection currents

5. Doldrums and Horse Latitudes
Areas of calm with no strong surface winds
Doldrums located at equator where air constantly rises
Horse latitudes = areas where cold air sinks

6. Trade Winds Blow towards the equator
Coriolis effect causes winds to curve west
For years sailors relied on them when traveling to South America and the West Indies

7. The Prevailing Westerlies
Winds blow towards the poles and turned west by Coriolis effect.
Have a huge impact on US weather

8. Polar Easterlies and Jet Streams
Polar easterlies flow towards the equator and turned west
Jet Streams = Bands of high-speed winds 10km above the earth’s surface
