Transcript of "Climate zones"

  1. 1. Weather & Climate<br />What is the difference between weather and climate? Or are they the same?<br />Climate is what we expect. <br />Weather is what we get.<br />
  2. 2. Coriolis Effect<br />What is the Coriolis effect? <br />The apparent curve of the winds on earth.<br />
  3. 3. Prevailing Winds<br /><ul><li>Air moving from a high pressure area to low pressure area = wind.
  4. 4. Westerlies:prevailing winds that go from west to east over the United States</li></li></ul><li>
  5. 5. Iceland Volcano Plume<br />What could happen if there are more large eruptions in the near future?<br />The Year Without a Summer 1816: Caused by the 1815 Eruption of Mount Tambora in Indonesia. <br />93 cubic miles of ash into the stratosphere.<br />Many parts of the world had snow in summer, heavy rainfall, crop failures, disease and starvation due to lack of sunlight.<br />
  6. 6. Check your understanding…<br />So why is it important to know the direction winds blow at different latitudes?<br />Sailing (exploration, trading, pirates in the Caribbean)<br />Predict weather conditions<br />
  7. 7. Earth’s surface features affect weather and climate<br /><ul><li>Variations in Earth’s topography affect the climate of a region
  8. 8. Mountains
  9. 9. Plains
  10. 10. Oceans/Great Lakes</li></li></ul><li>Mountains<br />Review <br />Mountains=Rain Shadow Effect<br /><ul><li>Prevailing windscarry moist air up windward side of mountains
  11. 11. Air rises over mountain, cools and condenses (forms clouds). Air loses capacity to hold moisture = precipitation (rain/snow)</li></li></ul><li>Rain shadow…..<br /><ul><li>Leewardsideof mountain-- cool, dry air warms as it descends.
  12. 12. Deserts can form on leeward side of mountain.</li></li></ul><li>
  13. 13. Rocky Mountain Rain Shadow<br />
  14. 14.
  15. 15. Altitude<br />Altitude=Cooler temperatures<br />Snow on mountains near the equator<br />
  16. 16. Oceans and Large Lakes<br />Oceans and Great Lakes<br /><ul><li>Large bodies of water moderate temperature on nearby land
  17. 17. Oceans heat up and cool down SLOWER than land

  20. 20. Nothing to stop wind flow
  21. 21. Winds and moisture merge
  22. 22. Mixing of winds create severe thunderstorms and........</li></li></ul><li>Tornadoes!<br />Aurora, CO June 2009<br />
  23. 23. Aurora’s Weather and Climate<br />Use the information you have learned today and your experience with the weather in Aurora to answer the question:<br />“What factors influence the weather and climate we have in Aurora?”<br />Use at least 4 of these words/phrases in your explanation:<br />Rain shadow, plains, leeward, Westerlies, proximity to the ocean, windward, altitude.<br />
  24. 24. Latitude and Climate Zones<br />Latitude: The distance of a place north or south of the equator <br />(remember: latitude=ladder)<br />Equator: 0o = warmest weather all year<br />Temperatures get cooler the further north and south you go<br />
  25. 25. Climate Zone Maps<br />How to correctly color your maps:<br />Leave lakes and oceans UNCOLORED<br />Take time to look at the map when coloring. Can you predict the climate of a region by its terrain, distance from equator or poles, or proximity to water?<br />Use a different color for each climate zone if you can.<br />1. Begin the reading. <br />When you read POLAR ZONES: ICE CAPS, pick your first color and color the word ICE CAPS. Select a new color for TUNDRA and do the same. Read the POLAR ZONES paragraph and then color in the polar zones on the map. (ICE CAP=A and TUNDRA=B)<br />Repeat the same process for each climate zone. <br />
