Sun affects ocean currents. The sun heats the atmosphere creating winds and movement in the sea surface through friction Wind blows hard that cause movement in the water surface creating ocean currents. Sun alters density of the ocean surface water by changing its temperature and its salinity

Sun affects ocean currents
Sun affects ocean currents

  • The sun heats the atmosphere creating winds and movement in the sea surface through friction

  • Wind blows hard that cause movement in the water surface creating ocean currents.

  • Sun alters density of the ocean surface water by changing its temperature and its salinity

  • When water is cooler or saltier because of evaporation, density of water increase, and this can result that water can be unstable.

Wind patterns
Wind patterns

  • Wind patterns is also known as general circulation

  • When the sun heats directly the region is the equator- sun heats the air and leaves low pressure areas

  • Winds are affectedbythe Coriolis effect

  • Thearea of calm is called doldrums- no steady surface winds


Wind patterns1
Wind patterns

  • Wind patterns:

  • Tropical Easterlies: 0-30 degrees latitude- warm, steady winds that blow almost always.

  • Prevailing Westerlies: 30-60 degrees latitude- winds that move to the poles curve to the east

  • Polar Easterlies: 60-90 degrees latitude- join with prevailing westerlies to reduce upward motion, they form when the atmosphere cools from the poles
