Presentation Transcript

  1. Wind Section 16-3

  2. Warm-up • Explain what you think causes WIND.

  3. WIND • Caused by a difference in AIR PRESSURE

  4. WIND • Horizontal movement of air from an area of High Pressure to an area of Low Pressure

  5. WIND

  6. Wind Speed • Measured with an Anemometer

  7. Anemometers

  8. Local Winds • Blow over short distances • Form only when no other winds are blowing from farther away. • Caused by unequal heating of Earth’s surface.

  9. Naming Winds • Winds are named by where they come FROM

  10. Sea Breeze

  11. Land Breeze

  12. Monsoons • Seasonal Land and Sea Breezes which occur annually

  13. Monsoons

  14. Monsoons

  15. Monsoons

  16. Monsoons

  17. Monsoons 250 cm = 98 in PA = 41 per year, about 3 per month

  18. Global Winds • Caused by the movement of air from the poles to the equator

  19. Sunlight hits most directly at the Equator

  20. Doldrums • Near the Equator • Warm air is rising, so there is little or no wind

  21. Doldrums

  22. Global Wind - principle

  23. Global Wind - reality

  24. Global Winds

  25. Coriolis effect • Winds curve because of the spinning of the earth

  26. Coriolis effect

  27. Jet Stream
