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

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

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

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

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

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

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

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
