Heat engine: heated air at the equator rises, low pressure moving to higher latitudes and then sinks. It
generates water currents. Hadley cell:
Coriolis: movement of fluid in relation to earth beneath result in deflections of the water. It is caused by
the earth rotation (things at the equator move faster than things at the poles), gravity and centrifugal
Gyres: combination of winds systems and shapes of ocean basins create cyclonic flow. Where gyres
interact with land masses the wind plus the Coriolis effect tends to concentrate boundary currents on
west sides of the ocean.
The Coriolis effect causes each successive sheet of water to deflect to the right relative to the sheet
above at 90 degree. Heat engine cause pressure deflection. Winds are affected by the rotation of the
earth and this generates: trade winds and prevailing westerlies.
California current is cold south, Atlantic brings warm water to the tropiques. Eddies bring warm water
up (warm core wings). Cold core wings move south (California currents because moving from cold to
Upwelling is the upward mov
