Pg tp-class16-worldwide temperature variations

  1. 1. Class 16: Worldwide Temperature Patterns
  2. 2.  Latitude  Season  Time of day
  3. 3. 1 2 3 4 0% 0%0%0% 1. Increases temp 2. Decreases temp 3. Increases temps in day, but decreases them at night 4. Increases temps at night, but decreases them during day
  4. 4. 1 2 0%0% 1. Increases temperature 2. Decreases temperature
  5. 5.  Atmospheric Obstruction (effect of clouds, gases, particulates)  Daylength  Latitudinal Radiation Balance
  6. 6.  Then where does the “extra” heat from the tropics go?
  7. 7. 1 2 3 4 5 20% 20% 20%20%20%1. Into the earth 2. Escapes into space 3. Hotter air rises in troposphere 4. Moves toward poles 5. All of above
  8. 8. 1 2 0%0% 1. Land 2. Water
  9. 9. 1 2 0%0% 1. Land 2. Water
  10. 10. 1 2 0%0% 1. Wichita, Kansas 2. San Francisco, CA (same latitude)
  11. 11. 1 2 0%0% 1. Wichita, Kansas 2. San Francisco, CA
  12. 12. Water has a moderating effect on temperature!
  13. 13. Movement And Mixing
  14. 14.  In the next slides, look at the color-coded isotherms (lines of equal temperature).  What patterns do you notice in the isotherms?  How do they change from January to July?
  15. 15.  Generally, Isotherms run east to west  Pulled northward in July, southward in January
  16. 16.  Generally, Isotherms run east to west  Pulled northward in July, southward in January  Areas covered by glaciers (Antarctica, Greenland) are cold all year round
  17. 17.  Generally, Isotherms run east to west  Pulled northward in July, southward in January  Areas covered by glaciers (Antarctica, Greenland) are cold all year round  In southern hemisphere, land other than Antarctica stays warmer in winter than land in northern hemisphere. Why?
  18. 18.  Generally, Isotherms run east to west  Pulled northward in July, southward in January  Areas covered by glaciers (Antarctica, Greenland) are cold all year round  In southern hemisphere, land other than Antarctica stays warmer in winter than land in northern hemisphere. Why?  Hottest areas in summer are interiors of continents  Coldest areas in winter are interiors of continents
  19. 19.  Generally, Isotherms run east to west  Pulled northward in July, southward in January  Areas covered by glaciers (Antarctica, Greenland) are cold all year round  In southern hemisphere, land other than Antarctica stays warmer in winter than land in northern hemisphere. Why?  Hottest areas in summer are interiors of continents  Coldest areas in winter are interiors of continents  Locations near the water (especially on windward side of continents) tend to be warmer in winter and cooler in summer
