The large circular-moving current systems that are within an ocean basin are called?
'gyres' there are 5 main gyres; North Pacific, South Pacific, North Atlantic, South Atlantic and the Indian Ocean.
Do oceans affect weather?
This question is the same with the question:How do the oceans affect Earth?Relationship of the Ocean and the AtmosphereThe atmosphere affects the oceans and is in turn influenced by them. The action of winds blowing over the ocean surface creates waves and the great current systems of the oceans. When winds are strong enough to produce spray and whitecaps, tiny droplets of ocean water are thrown up into the atmosphere where some evaporate, leaving microscopic grains of salt buoyed by the turbulence of the air. These tiny particles may become nuclei for the condensation of water vapor to form fogs and clouds.In turn, the oceans act upon the atmosphere-in ways not clearly understood-to influence and modify the world's climate and weather systems. When water evaporates, heat is removed from the oceans and stored in the atmosphere by the molecules of water vapor. When condensation occurs, this stored heat is released to the atmosphere to develop the mechanical energy of its motion. The atmosphere obtains nearly half of its energy for circulation from the condensation of evaporated ocean water.Because the oceans have an extremely high thermal capacity when compared to the atmosphere, the ocean temperatures fluctuate seasonally much less than the atmospheric temperature. For the same reason, when air blows over the water, its temperature tends to come to the temperature of the water rather than vice versa. Thus maritime climates are generally less variable than regions in the interiors of the continents.The relationships are not simple. The pattern of atmospheric circulation largely determines the pattern of oceanic surface circulation, which in turn determines the location and amount of heat that is released to the atmosphere. Also, the pattern of atmospheric circulation determines in part the location of clouds, which influences the locations of heating of the ocean surface.Currents and Ocean CirculationSurface CirculationThe surface circulation of the oceans is intimately tied to the prevailing wind circulation of the atmosphere. As the planetary winds flow across the water, frictional stresses are set up which push huge rivers of water in their path. The general pattern of these surface currents is a nearly closed system of currents, called gyres, which are approximately centered on the horse latitudes (about 30° latitude in both hemispheres). Major circulation of water in these gyres is clockwise in the Northern Hemisphere and counterclockwise in the Southern Hemisphere. In the North Pacific and North Atlantic oceans, smaller counterclockwise gyres are developed partly due to the presence of the continents. These are centered on about 50°N lat. The most dominant current in the Southern Ocean is the West Wind Drift, which circles Antarctica in an easterly direction. The northern and southern hemispheric gyres are divided by an eastward flowing equatorial countercurrent, which essentially follows the belt of the doldrums. This countercurrent is caused by the return flow of water piled up along the eastward portion of the equatorial seas, and its return flow is uninhibited by the weak and erratic winds of the doldrums. Analysis of current records shows that a number of major currents, such as the Gulf Stream, have strong fast-moving currents beneath them trending in the opposite direction to the surface current. Such undercurrents, or countercurrents, appear to be as important and pervasive as the surface currents. In 1952 the Cromwell current was found flowing eastward beneath the south equatorial current of the Pacific. In 1961 a similar current was discovered in the AtlanticThermohaline CirculationThermohaline circulation refers to the deepwater circulation of the oceans and is primarily caused by differences in density between the waters of different regions. It is mainly a convection process where cold, dense water formed in the polar regions sinks and flows slowly toward the equator. Most of the deep water acquires its characteristics in the Antarctic region and in the Norwegian Sea. Antarctic bottom water is the densest and coldest water in the ocean depths. It forms and sinks just off the continental slope of Antarctica and drifts slowly along the bottom as far as the middle North Atlantic Ocean, where it merges with other water. The circulation of ocean waters is vitally important in dispersing heat energy around the globe. In general, heat flows toward the poles in the surface currents, while the displaced cold water flows toward the equator in deeper ocean layers.I hope this answers your question.

What are gyres and what is the difference between gyres in the northern hemisphere and southern hemisphere?
Gyres flow clockwise in the Northern Hemisphere. While gyres in the Southern Hemisphere flow counterclockwise.
Describe the similarities and differences between gyres and currents?
A difference between gyres and currents is that currents are formed by the wind, but gyres are formed by currents.
Do the gyres of the northern hemisphere circulate in a counterclockwise direction?
gyres in the northern hemisphere circulate clockwise, while the gyres in the southern hemisphere circulate counterclockwise
What is difference similiarity currents and gyres?
similarity is currents form gyres. difference is currents are any movement of water in one specific direction and gyres are circular patterns of water
How are gyres made?
vf
Where are the 5 major gyres?
there are five gyres in the world, they are the north pacific, the south pacific, the north Atlantic, the south Atlantic, and the Indian ocean gyres.
Why are the gyres in the northern hemisphere separate from the gyres in the southern hemisphere?
The Coriolis effect, caused by the Earth's rotation, influences the direction of the currents in each hemisphere. This effect leads to clockwise gyres in the northern hemisphere and counterclockwise gyres in the southern hemisphere, creating separate systems due to the opposite directions of motion. The difference in wind patterns and landmass distributions also contribute to the distinct gyres in each hemisphere.
How do gyres form?
The Coriolis effect.
Why do gyres flow in giant circular patterns?
its because currents form gyres and the wind is so much that it found a circular patterns
What are large roughly circular ocean c urrents called?
Large, roughly circular ocean currents are called gyres.
Why do major surface current gyres in the northern hemisphere flow clockwise?
The Coriolis effect causes northern gyres to spin clockwise.
How many gyres are in the northern hemisphere?
4
