Wind Driven Circulation
Cards in this deck (15)
- 11 Sverdrup10^6 m^3/sec
- 2North Atlantic Gyre- Western boundary Current = Gulf Stream (fast)
- Eastern Boundary Current = Canary Current (slow) - 33 Gyres of North Atlantic Subtropical Gyre- Gyre 1: Loop of Gulf Stream
- Gyre 2: N.Atlantic, East Greenland, West Greenland
- Gyre 3: Gulf Stream Loop, Florida, N. Atlantic, Canary, N. Equatorial - 4Subtropical North Pacific Gyre- Kuroshio Current, N. Pacific C., Alaska C., California C.
- Gulf Stream, N. Atlantic, Norwegian, Canary
- Most water moved in this gyre
- Center is called Great Pacific Garbage Patch - 5Great Pacific Garbage Patch- In center of N. Pacific Gyre
- 6 kg of plaster per 1 kg of plankton
- 2x size of Texas
- Majority is microscopic - 6Western Boundary Currents- Gulf Stream
- Brazil
- Kuroshio
- East Australian
- Somali
- Agulhas (does 180 degree turn - retroflection - and breaks off into the Atlantic - 7Eastern Boundary Currents- Canary
- Benguela
- California
- Peru
- West Australian - 8Somali Current- Very small eastern boundary current
- Clockwise in the summer and counter clockwise in the winter; not present in between - 9North East Monsoon- Occurs in winter
- Cold, dry air sweeps over Indian Ocean - 10South West Monsoon- Occurs in summer
- Moisture hits mountains and collects and carries water to produce heavy rains - 11Antarctic Circum Polar Current- A full loop and only current in the world that goes all the way around earth
- Very deep and wide: T~~200Sv
- Eastward flowing geostrophic current
- Flows for 24,000 km
- Carries largest water by a current in the world - 12Equatorial Counter Current- Lies between 10 degrees North and 40 degrees North
- Between the South Easterly Current and North easterly Current
- Present in all ocean basins - 13South Easterly Current- Between 3 degrees North and 10 degrees South
- Fed by South East Trade Winds that go over the equator - 14North Easterly Current- Between 10 degrees North and 25 degrees North
- Fed by North East Trade Winds - 15Equatorial Undercurrent- Flows east
- In all 3 oceans
- Fastest current going at speed= 1.5 m/s or T = 30Sv
- Only 200m thick
- Between 2 degrees North and 2 degrees South
- Always in thermocline
- Only current that's not geostrophic because it doesn't interact with surface winds directly
