atmosphere ocean circulation
Atmosphere & Ocean Circulation
  • Atmospheric Circulation
    • Depends on density
  • Ocean Surface Circulation
    • Depends on the wind
  • Deep Ocean Circulation
    • Depends on density
why is ocean circulation important
Why is Ocean Circulation Important?
  • Transport ~ 20% of latitudinal heat
    • Equator to poles
  • Transport nutrients and organisms
  • Influences weather and climate
  • Influences commerce
wind drive ocean surface currents

Wind driven surface currents

Wind-drive ocean surface currents
  • How fast? A few miles/hr (Gulf Stream off of Miami = 4.5 mph)
  • How much?Total water in ocean surface circulation = about 100 Amazon Rivers (20 million m3/s).
