1. Coriolis Effect Global Winds Chapter 2.3 Pages 57-60 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 Winds that blow steadily from specific directions over long distances. Caused by unequal heating of the surface.

6. Global Winds

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

9. Doldrums Located: At the equator Area of Low PressureArea of Low Pressure –Rising Air Definition: a state of inactivity or stagnation Winds: Calm

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

11. Trade Winds 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.

12. Prevailing Westerlies 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.

13. Polar Easterlies BetweenLocation: 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.

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