How do ocean currents affect the climate?

Sagot :

The ocean currents affect the climate by storing solar radiation, distributing heat and moisture around the globe, and driving weather systems.

Horizontal currents moving northward or southward may carry warmed or cooled water for very long distance. The displaced warm water raises the temperature of the air while the cold water cools the air, and the land surface where the blows.

What is an Ocean Current?

An Ocean currents are a continuous and directed movement of the ocean water. This happens through forces acting on the water, such as difference in salinity, the waves breaking, temperature, the wind or even the Coriolis effect.  

Two types of Ocean Currents:

1. Surface Currents--Surface Circulation

  • These waters make up about 10% of all the water in the ocean.
  • These waters are the upper 400 meters of the ocean.

2. Deep Water Currents--Thermohaline Circulation

  • These waters make up the other 90% of the ocean.
  • These waters move around the ocean basins by density driven forces and gravity.
  • The density difference is a function of different temperatures and salinity.
  • These deep waters sink into the deep ocean basins at high latitudes where the temperatures are cold enough to cause the density to increase.

Causes Of Ocean Currents

  • Pressure gradients
  • Coriolis effect
  • Frictional forces
  • Geostrophic currents
  • Ekman layer

Warm And Cold Currents

Cold ocean currents- are masses of cold water moving from high latitude towards the equator absorbing the heat received in the tropics thus cooling the air above. Cold currents are formed when the air circulating the eastern side of the subtropical high is blown over cold water mass and are then dragged toward the equator.

Warm currents- are masses of warm water with higher temperatures moving away from the equator. Warm currents are formed when the cold saline water becomes dense and sinks allowing the light warm water to flow in the opposite direction, usually far from the equator.

Ocean Current Movement

The ocean currents can flow for thousands of kilometers and create a global conveyer belt which is important in determining the climate of different regions of the earth. Ocean currents are either on the surface of the ocean or in the deep waters below 300 meters. The currents can also move either horizontally or vertically depending on the cause. The ocean currents can also be influenced by the shape of the ocean basin, topography, and the land masses bordering the Ocean.
