  1. CRCT Question Air in the atmosphere has pressure because: It has mass It changes temperature It has volume It has clouds

  2. Warming Up With A HEAT Rap

  3. Chapter 15 Wind in our atmosphere

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

  5. 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.

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

  7. Local winds Most often noticed at the beach!

  8. 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.

  9. 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.

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

  11. 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

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

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

  14. 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

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

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

  17. Jet Streams

  18. 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

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

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

  21. Summary Do you know the difference between sea breeze and land breeze? Using the diagram provided, fill in the blanks on each side of the piece of paper!

  22. Projects Each layer must include: • Temperature • Width of the layer • 2 or more special features • Visual Representation • Pressure • Entry and exit
