Currents of the Indian Ocean: Being only half an ocean, completely landlocked in the north, the characteristic current circulation of the Indian Ocean is different from that of Atlantic or the Pacific Ocean. The Atacama desert in South America is influenced by the cold Peru current. We write simple, easy to understand articles, but always ensure high standards of quality. Near the equator the water is about 8 centimeters high than in middle latitudes. The general pattern of circulation is simple and is anticlockwise like that of the other southern oceans. General Characteristics of Ocean Currents : These characteristics arise as a result of interplay of the above-mentioned factors and include the following: 1. .
The two cold currents—East Greenland current and the Labrador Current—flow from the Arctic Ocean into the Atlantic Ocean. Western margins of Subtropical anti-cyclones. Its northern branch reinforces the north equatorial current. Another example is , where the climate is cooler, being sub-tropical, than the tropical latitudes in which the area is located, due to the effect of the. 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. Because water is dense, it carries an enormous amount of energy that could possibly be captured and converted into a usable form through the use of water turbines.
In the northern hemisphere they are found on the west coasts of continents in high latitudes. Unusual high and low tides occur during this time. For example, it has real-time coastal meteorological, oceanographic, and hydrologic observations. The western coast of Europe is an example of such a region. These waters move around the ocean basins due to variations in the density and gravity.
Whether ocean currents are used as alternative energy, to reduce shipping costs, or in their natural state to move species and weather worldwide, they are significant to geographers, meteorologists, and other scientists because they have a tremendous impact on the globe and earth-atmosphere relations. The south equatorial current bifurcates into two branches near Cape de Sao Roque Brazil. Example: Summer Rainfall in British Type climate. Besides that, the current also can help managing the temperature basically because the ocean water will absorb about 30% of the total carbon dioxide on earth. Places where cold and warm currents meet are ideal for the growth of Plankton. Besides, in the southern hemisphere the current will flow counterclockwise.

This also creates a gradient and results in the movement of waters from equatorial region to middle and upper latitudes. The ocean currents can also be influenced by the shape of the ocean basin, topography, and the land masses bordering the Ocean. These areas lie in the western margins of the subtropical anti-cyclones. The Humboldt Current is another example of a current that affects weather. Water will pile up in the direction the wind is blowing. If no button appears, you cannot download or save the media.
This is may happened because of some factors that affect the movement of the water it self. Since, not all kind of animal and ocean plants can live in a high temperature. Mounds in the water form in areas where the water meets land, where water is warmer, or where two currents converge. Warm currents are those which flow from the low latitudes in tropical zones towards the high latitudes in the temperate and sub-polar zones. For example, ocean currents in the northern hemisphere spins mostly clockwise.
Secondary Forces- -influence where the currents flow 1. These currents also affect temperatures throughout the world. Consequently, the lower layer moves slower than the layer above. The ocean currents direction is also being affected by some factors. Currents of the Atlantic Ocean: As in the Pacific Ocean, the two equatorial currents move from east to west in northern and southern hemispheres and a counter-equatorial current flows from west to east. Such currents are caused by the differences in salinity and temperature. These are very small organisms, which are food for fish.
Similarly many tropical species of fish are found in the southwest of Australia that hitch a ride on the. The changes in current movements affect the coastal climate by carrying a lot of heat. The stronger the wind, the bigger the wave. Currents driven by thermohaline circulation occur at both deep and shallow ocean levels and move much slower than tidal or surface currents. That is why, near the equator the ocean water is about 8 cm higher in level than in the middle latitudes.
In Northern hemisphere, they are found in west coast in Northern hemisphere. Today, ocean currents are also gaining significance as a possible form of alternative energy. Like the winds controlling them, these surface currents help redistribute heat at a planetary scale: Generally speaking warm water flows toward the poles and cold water flows toward the equator. Oceanic currents are found all over the globe and vary in size, importance, and strength. As we begin to better understand our oceans, these maps keep track of their dynamic nature. They change their direction from season to season in response to the seasonal rhythm of the monsoons. Surface currents are those found in the upper 400 meters 1,300 feet of the ocean and make up about 10% of all the water in the ocean.
