Climate Change, how ocean currents affect climate?
Ever wondered how ocean currents affect climate? Ocean currents are a continuous and direct movement of the ocean water. This happens through forces acting on the body of water, such as difference in brininess, the waves breaking, temperature, the scent or even the Coriolis consequence. The direction of the current is determined by the depth of the contours, other currents acting on the ocean and the nature of the shoreline.
The currents will travel thousands of kilometers, in the process establishing a conveyer belt globally that brings about different climatic conditions across the world. The currents will either act above the surface of the ocean, or cryptic below the surface of the ocean ( at least 300 meters ). Depending on the cause, ocean currents will move vertically or horizontally, and they can also be influenced by the land masses that border the ocean, the topography or the shape of the ocean basin.
How climate is determined by ocean currents
As the horizontal currents are moving south or northwards, they carry with them cool or warm water over an extended distance. It is the displace water system that affects the air, by warming or cooling it, thereby transferring the lapp effect to the land surface over which it blows. This is how ocean currents affect climate.

Warm and cool ocean currents
Cold ocean currents are large masses of cold water that move towards the equator, from a level of high altitude to lower levels. They absorb the heating system they receive in the tropics, thereby cooling the atmosphere above them. The cold currents often form when the air on the subtropical high blows over a coldness mass of water, then the cold air is dragged to the equator .
warm currents, on the other hand, are big masses of affectionate water moving promote away from the equator, at higher temperatures. They form when piquant cold water system becomes heavy and sinks, in the serve forcing affectionate and light water to move in the opposite steering .
The influence of the flow of currents usually depends on the level of saltiness of the water, the rotation of the earth, the topography of the land and the orientation of the wind. It is these that bring cold water to the surface of the earth from the depths, and in the process forcing away the original surface water. It is because of this reason that you will always notice that the ocean is often cooler to the eastern coastal side than the western coastal side.
