What is the relationship between atmospheric circulation and circulation in the ocean?
Heat from the atmosphere is also absorbed by the ocean. This heat is then transported by ocean circulation patterns and re-radiated from the oceans influencing regional air temperatures. Atmospheric circulation transports heat and water above the Earth’s surface.
What is the atmospheric circulation model?
The global atmospheric circulation model is a simplified version of how air currents in the atmosphere move. It is used to help explain weather patterns and climatic regions. The global atmospheric circulation model is based around cells. These cells are regions where the air moves from low pressure to high pressure.
How are atmospheric and ocean circulation alike and different?
Answer: Atmospheric circulation is the large-scale movement of air and together with ocean circulation is the means by which thermal energy is redistributed on the surface of the Earth.
In what ways are atmospheric and oceanic circulation patterns different?
How are they different? They are similar because they both move by the Earth’s rotation and heating causes currents in both patterns. They are different because in the atmosphere there are winds and cells and in the ocean there are hot/cold currents and upwellings.
What do you mean by ocean circulation?
Ocean circulation is the large scale movement of waters in the ocean basins. Winds drive surface circulation, and the cooling and sinking of waters in the polar regions drive deep circulation. Surface circulation carries the warm upper waters poleward from the tropics.
What are the 3 types of atmospheric circulation cells called?
The global circulation In each hemisphere there are three cells (Hadley cell, Ferrel cell and Polar cell) in which air circulates through the entire depth of the troposphere. The troposphere is the name given to the vertical extent of the atmosphere from the surface, right up to between 10 and 15 km high.
What is ocean circulation pattern?
Sometimes called the thermohaline conveyor belt, this circulation pattern moves cold water around the globe in deep water currents and warmer water in surface currents. A single molecule of water being transported by thermohaline circulation may take a thousand years to move completely throughout the Earth’s oceans.
How patterns of atmospheric and oceanic circulation determine regional climates?
Patterns of atmospheric and oceanic circulation that determine regional climates vary by latitude, altitude, and geographic land distribution. Atmospheric circulation that, in part, determines regional climates is the result of sunlight-driven latitudinal banding, the Coriolis effect, and resulting prevailing winds.
What two factors cause the patterns of atmospheric and oceanic circulation?
The global conveyor belt’s circulation is the result of two simultaneous processes: warm surface currents carrying less dense water away from the Equator toward the poles, and cold deep ocean currents carrying denser water away from the poles toward the Equator.
What are the two types of ocean circulation?
Ocean circulation derives its energy at the sea surface from two sources that define two circulation types: (1) wind-driven circulation forced by wind stress on the sea surface, inducing a momentum exchange, and (2) thermohaline circulation driven by the variations in water density imposed at the sea surface by …
