  1. Coriolis EffectGlobal Winds Chapter 2.3 Pages 57-60

  2. Coriolis Effect • The effect of Earth’s rotation which makes winds curve • Winds want to move in a straight line but the earth rotates under them, making it seem as though the wind curved.

  3. Coriolis Effect • In the Northern hemisphere Earth rotates counter clock wise • All winds curve to the right.

  4. Coriolis Effect • In the Southern hemisphere Earth rotates clock wise • All winds curve to the left.

  5. Global Winds Polar Easterlies • Winds that blow steadily from specific directions over long distances. • Caused by unequal heating of the surface. Westerlies Horse Latitudes Trade Winds Doldrums Trade Winds Horse Latitudes Westerlies Polar Easterlies

  8. Exit Pass What is the Coriolis Effect? (Why does it happen, and what does it cause?)

  9. Doldrums • Located: At the equator • Area of Low Pressure • Rising Air • Definition: a state of inactivity or stagnation • Winds: Calm Horse Latitudes L Doldrums Horse Latitudes

  10. Horse Latitudes • Located:30°N and 30°S • Area of high pressure • Sinking air • Winds: Calm • Sailors would get trapped and run out of food and water, they threw their horses overboard. H Horse Latitudes Doldrums H Horse Latitudes

  11. Trade Winds Polar Easterlies • Between the • Equator and 30°N • Equator and 30°S • Winds: Steady from the east • Sailors relied on them to carry goods from Europe to West Indies and S. America. Westerlies Trade Winds Trade Winds Westerlies Polar Easterlies

  12. Prevailing Westerlies Polar Easterlies • Location: Mid-latitude winds • Between 30° & 60°N • Between 30° & 60°S • Winds: From the west • Cause our weather • Blow away from the horse latitudes. Westerlies Trade Winds Trade Winds Westerlies Polar Easterlies

  13. Polar Easterlies Polar Easterlies • Location: Between • 60°N and 90°N • 60°S and 90°S • Winds:FROM the east to west • Cold, low pressure air from the poles sinks and flows away from the pole to the equator. Westerlies Trade Winds Trade Winds Westerlies Polar Easterlies

  14. Jet Stream • 10km above the Earth’s surface • Bands of high speed winds • 200-400km/hr • Blow from west to east • Wanders north and south.

  15. Exit Pass Describe two of the Global Winds (Where is it located, H or L pressure, direction, etc.)
