  3. AtmosphereDiscussionQ’s Did you write in COMPLETE SENTENCES?!?!

  4. Review Wind in our atmosphere

  5. Wind is caused by the unequal heating of the earth!

  6. Important fact! Wind is always named by where it is coming from! What would a wind be named (North or South) if it is blowing from Georgia to Florida? It is called a NORTH wind because it is moving from the north to the south.

  7. Two main types of wind: 1. Local - small area 2. Global - across continents due to the Coriolois effect

  8. Type 1 Local Winds Most often noticed at the beach!

  9. Caused By: Unequal Heating Within a small area!

  10. http://www.coolweather.co.uk/ • Land heats up faster than water. • Warm air over land rises. • Air over water moves to shore. • Would occur during the day. • Named a SEA breeze because it comes from the sea.

  11. http://www.coolweather.co.uk/ • Land cools off faster than water. • Warm air over water rises. • Cool air from land takes its place. • Would occur at night. • Called a LAND breeze because the wind is coming from the land.

  12. Closer Look at Local Wind When Air WARMS up • When air heats up, it loses mass and becomes less dense. • The air becomes more spread out • Because of this, warm air will rise When Air COOLS down • When air cools down, it gains mass and becomes more dense • The air will sink

  13. Look at these two diagrams. Can you tell which is the land breeze and which is the sea breeze?

  14. Animated Version http://www.classzone.com/books/earth_science/terc/content/visualizations/es1903/es1903page01.cfm

  15. Type 2 Global Winds 1. Blow steadily from the same direction all the time. 2. The path is curved because of the Coriolis Effect. http://cimss.ssec.wisc.edu

  16. Types of Global Winds • Polar easterlies • Westerlies • Trade winds

  17. Remember! Winds are named according to where originate, or come from.

  18. Polar Easterlies • From the POLES • Wind belts that extend from the poles to 60° latitude • Formed from cold sinking air moving from the poles creating cold temperatures

  19. Westerlies • Wind belts found between 30° and 60° latitude • Flow towards the poles from west to east carrying moist airover the Unites States

  20. Trade Winds • Winds that blow from30° almost to the equator • Called the trade winds because of their use by early sailors

  21. Jet Streams

  22. Jet Stream • Very fast 200-400 kmh • Acts like a conveyor belt • Goes completely around the earth. • In US, it makes weather generally blow east to west • Measured by anemometer

  23. Notice that the jet stream does not stay the same every day. But it is always there!

  24. Notice on this weather map in motion how the rain moves toward the east over time.

  25. Whiteboard Review

  26. Global or Local Wind ????? Air over land is cooler and forms an area of high pressure. The cool air moves toward the ocean. Polar Easterlies Generally moves over short distances Jet stream Caused by unequal heating over a large area Can blow from any direction Land breeze Is effected by the Coriolis Effect Caused by unequal heating within a small area Valley breeze

  27. The Doldrums • Blows from a specific direction from day to day • Sea breeze • Horse latitude • Effected by local geographic features • Westerlies • Caused because the angle of the sun giving the equator more direct sunlight • Mountain breeze • Trade winds • During the day, air over the ocean is cooler and forms an area of high pressure. The cool air flows to the land

  28.

  33. Answer Troposphere Stratosphere Mesosphere Thermosphere

  34. Question Water vapor is in what form?

  35. Answer vapor

  36. Question Which layer contains the ozone Layer?

  37. Answer Stratosphere

  38. Question The less mass in a given volume of air, the __________dense in the air

  39. Answer less

  40. Question Layers of the atmosphere are divided based on:

  41. Answer Temperature

  42. Question What is the FORMULA for density?

  43. Answer Density = mass/volume
