  1. Homeroom Drop everything and read!

  2. Warm-up • Read the article “Early Europeans and the trade winds”. • Answer theses questions in your notebook: • What was the Age of Discovery? • Which winds did early Europeans often use? • How did the trade winds get their name? • Which winds did sailors use in the Indian Ocean? • Explain why winds were important for life during this time.

  3. Warm-up • Write one sentence about each of the following. • Troposphere • Stratosphere • Mesosphere • Thermosphere

  4. Wind • Air that moves horizontally, or parallel to the ground.

  5. What causes wind? • Uneven heating of the earth causes air pressure differences • This sets air in motion!

  6. Wind moves from an area of high pressure to an area of low pressure.

  7. Global Winds • Travel thousands of kilometers in the same patterns

  8. What causes global winds? • Uneven heating (pressure differences!) between the north and south pole

  9. Coriolis Effect • Drop one drop of water on the cardboard circle while it is sitting still. • Drop another drop and spin the circle. ANSWER IN NOTEBOOK: What happened to the drop when you spun the circle? What does Earth’s rotation do to winds on Earth.

  10. Coriolis Effect • Earth’s rotation causes winds to curve

  11. Doldrums • Very calm! • Low pressure zone near the equator • Warm air rises to the troposphere • This produces clouds and rain

  12. Horse Latitudes • Very calm! • High pressure zone • Located 30 degrees north and south of equator • Weather is clear and dry • Called the horse latitudes because sailors would get stuck here and have to through their horses overboard!

  13. Trade winds • Blow from the east • From the horse latitudes to the equator • Strong and steady but die at the equator

  14. Westerlies • Blow from the west • From the horse latitudes to the poles • Bring storms across the USA

  15. Easterlies • Blow from east • From the poles to mid-latitudes • Stormy weather when cold air from easterlies meet warmer air from the westerlies!

  16. Local Winds • Some winds change daily in a regular pattern. • Sea breezes and land breezes occur near shoreline. • Use pg. 53 to sketch these!
