Ocean circulation patterns and atmospheric relationship

ocean circulation patterns and atmospheric relationship

What is the relationship between ocean circulation patterns and atmospheric circulation? Answer. The cirrculation in the subject of science, is where you blood. Ocean currents, including the ocean conveyor belt, play a key role in determining how the ocean distributes heat energy throughout the planet, thereby regulating and stabilizing climate patterns. energy moves between the Earth's water bodies, landmasses, and atmosphere. . Ecological Relationships. Land reflects much of the sun's radiation and the atmosphere can only all affect the patterns in which the water of the ocean moves (currents).

The Gulf Stream takes very warm water from the Gulf of Mexico and parts of the Caribbean Sea and transports it northward.

During the winter, the Gulf Stream can have a great effect on storm systems along the East Coast of the United States. It used to be thought that the flow of the Gulf Stream alone helped keep Europe warm in winter, but it has been recently shown that the temperate climate of Great Britain comes from warm air moving along with the Gulf Stream over the Atlantic Ocean.

This keeps temperatures along the western coast of Europe milder than continental areas farther east away from the coast.

The Flow of the Gulf Stream. How does ocean density affect ocean circulation? Deep ocean currents are primarily driven by ocean density. In order to understand how density can affect ocean circulation, we need to understand what density is.

Density for salt water depends on two things: A more common name for this kind of circulation is known as a thermohaline circulation.

Although warmer ocean water near the surface of the ocean is less dense and contains less salt than colder, deeper ocean water, warm water actually is capable of holding more salt than cold water. So why is the deeper, colder water saltier than the warmer, surface-based seawater?

It is due to freshwater runoff.

As a result, the water at the ocean surface is less salty than the water below it. The Gulf Stream maintains a warming influence in July, but it is not as noticeable because of the effects of continentality.

The ocean, particularly in areas where the surface is warm, also supplies moisture to the atmosphere. This in turn contributes to the heat budget of those areas in which the water vapour is condensed into clouds, liberating latent heat in the process. This set of events occurs frequently in high latitudes and in locations remote from the ocean where the moisture was initially taken up.

The great ocean currents are themselves wind-driven—set in motion by the drag of the winds over vast areas of the sea surface, especially where the tops of waves increase the friction with the air above.

At the limits of the warm currents, particularly where they abut directly upon a cold current—as at the left flank of the Gulf Stream in the neighbourhood of the Grand Banks off Newfoundland and at the subtropical and Antarctic convergences in the oceans of the Southern Hemisphere—the strong thermal gradients in the sea surface result in marked differences in the heating of the atmosphere on either side of the boundary.

These temperature gradients tend to position and guide the strongest flow of the jet stream see below Jet streams in the atmosphere above and thereby influence the development and steering of weather systems. Interactions between the ocean and the atmosphere proceed in both directions.

They also operate at different rates. Some interesting lag effects, which are of value in long-range weather forecastingarise through the considerably slower circulation of the ocean. Thus, enhanced strength of the easterly trade winds over low latitudes of the Atlantic north and south of the Equator impels more water toward the Caribbean and the Gulf of Mexicoproducing a stronger flow and greater warmth in the Gulf Stream approximately six months later.

Anomalies in the position of the Gulf Stream— Labrador Current boundary, which produce a greater or lesser extent of warm water near the Grand Banks, so affect the energy supply to the atmosphere and the development and steering of weather systems from that region that they are associated with rather persistent anomalies of weather pattern over the British Isles and northern Europe.

Anomalies in the equatorial Pacific and in the northern limit of the Kuroshio Current also called the Japan Current seem to have effects on a similar scale.
