  1. Chapter 4 Global Climate and Biomes

  2. Zonal weather pattern is not completely true The pattern is disrupted by land-sea contrasts Maui, HI San Diego, CA

  3. What warms up quicker: Land or Water? • Dry Air at room temperature – 1.01 Joules • Water at 25 C – 4.18 Joules • Based on these numbers, which warms up quicker? Why?

  4. Ocean Currents • Ocean currents are driven by: • Temperature • Gravity • Prevailing winds • Coriolis effect • Locations of continents

  5. Gyres • the large-scale patterns of water circulation

  6. Gyres • Redistribute heat in the ocean • Cold polar water along west sides of continents (vice versa east coasts) http://www.youtube.com/watch?v=J-gqJAsXiKQ

  7. Upwelling • as the surface currents separate, deeper waters rise and replace the water that has moved away • Cold H2O nutrient rich

  8. Thermohaline Circulation • Drives mixing of surface water and deep water • Crucial for moving heat and nutrients • Caused by surface waters with high salt content

  9. Thermohaline Circulation

  10. El Nino-Southern Oscillation

  11. Rain Shadow • Windward side – moist air rises and cools causing rain • Leeward side – air descends, higher pressure high temp (dry)
