What Is The Driving Force Of Oceanic And Atmospheric Circulation?


What Is The Driving Force Of Oceanic And Atmospheric Circulation??

Heat a form of energy helps drive ocean and atmospheric circulation. The ocean absorbs and stores more heat than the atmosphere.

What is the driving force of atmospheric circulation?

Atmospheric circulation is the movement of air at all levels of the atmosphere over all parts of the planet. The driving force behind atmospheric circulation is solar energy which heats the atmosphere with different intensities at the equator the middle latitudes and the poles.

What causes oceanic and atmospheric circulation?

Differences in water density resulting from the variability of water temperature (thermo) and salinity (haline) also cause ocean currents. This process is known as thermohaline circulation. In cold regions such as the North Atlantic Ocean ocean water loses heat to the atmosphere and becomes cold and dense.

What is the driving force of the ocean currents?

Surface currents in the ocean are driven by global wind systems that are fueled by energy from the sun. Patterns of surface currents are determined by wind direction Coriolis forces from the Earth’s rotation and the position of landforms that interact with the currents.

What are the two driving forces of this 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 …

What are the driving forces in the atmosphere that affect the wind?

The speed and direction of the wind is governed by three forces the pressure gradient force (PGF) the Coriolis Force and friction. PGF is the force produced by differences in barometric pressure between two locations and is responsible for the flow of air from an area of high pressure to an area of low pressure.

How is atmospheric circulation and oceanic circulation 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.

What forces are responsible for the movement of ocean water in currents What forces and factors influence the direction and nature of ocean currents?

Primary forces are thermal expansion and contraction of water the stress of wind blowing over the water and density differences between water layers. Secondary forces and factors are the Coriolis Effect gravity friction and the shape of the ocean basins themselves.

What causes atmospheric circulation?

Air in the atmosphere moves around the world in a pattern called global atmospheric circulation. … This pattern called atmospheric circulation is caused because the Sun heats the Earth more at the equator than at the poles. It’s also affected by the spin of the Earth. In the tropics near the equator warm air rises.

What would happen without atmospheric and oceanic circulation?

Thus ocean currents regulate global climate helping to counteract the uneven distribution of solar radiation reaching Earth’s surface. Without currents in the ocean regional temperatures would be more extreme—super hot at the equator and frigid toward the poles—and much less of Earth’s land would be habitable.

What is the driving force of ocean currents and atmospheric movement quizlet?

The sun is the driving force of oceanic and atmospheric circulations. It heat the earth unevenly causing convection currents in the air and ocean.

What is the driving force?

The impetus power or energy behind something in motion as in He was clearly the driving force in the new administration. This term transfers the force that sets in motion an engine or vehicle to other enterprises.

What are atmospheric cells?

The global atmospheric circulation model is based around cells. These cells are regions where the air moves from low pressure to high pressure. There are three cells in each hemisphere. Either side of the equator is the Hadley cell with the Ferrell cell next and then the Polar cell at the top and bottom of the planet.

What are the primary driving forces for the convection in the ocean?

Low temperature and high salinity are the primary driving forces of convection. They pull the dense water of the polar regions downward which drives a worldwide convection engine called thermohaline circulation (thermo – driven by temperature differences haline – driven by salinity differences).

What is the primary driving force of surface ocean currents quizlet?

1. Wind is the primary driving force of surface currents. The Coriolis effect deflects the currents to the right (Northern Hemisphere) or left (Southern Hemisphere) of their path of motion (the prevailing wind direction). The location of the continents also affects the pattern of surface currents.

What are the major forces that drive patterns of atmospheric movement Brainly?

Answer: Globally the two major driving factors of large-scale wind patterns (the atmospheric circulation) are the differential heating between the equator and the poles (difference in absorption of solar energy leading to buoyancy forces) and the rotation of the planet.

What is the main driving force of the global distribution of temperatures?

Directly or indirectly the sun provides energy for living organisms and it drives our planet’s weather and climate patterns. Because Earth is spherical energy from the sun does not reach all areas with equal strength.

What drives the movement of wind quizlet?

The wind is driven by differences in temperatures and pressures.

What is the driving force for the Hadley cell circulation pattern?

solar heating
Mechanism. The driving force of atmospheric circulation is the uneven distribution of solar heating across the Earth which is greatest near the equator and least at the poles.

What are the major forces that drive patterns of atmospheric movement quizlet?

The four factors that affect atmospheric circulation are as follows: the Coriolis Effect gravity friction forces and changes in air pressure.

How does atmospheric and oceanic circulation determine air temperature?

The circulation of the ocean is a key factor in air temperature distribution. The relative warmth of the Gulf Stream affects air temperatures all the way across the Atlantic and prevailing westerlies extend the warming effect deep into northern Europe. …

What is the driving force responsible for generating currents in the deep layer of the ocean?

These deep-ocean currents are driven by differences in the water’s density which is controlled by temperature (thermo) and salinity (haline). This process is known as thermohaline circulation.

What is the primary force driving the movement of ocean water in the Gulf Stream?

The driving force behind the Gulf Stream and other ocean currents is simple physics: In the waters west of Europe the evaporation of water makes the sea saltier and colder which makes the water more dense.

What forces are responsible for the movement of ocean water in current?

Ocean currents are the continuous predictable directional movement of seawater driven by gravity wind (Coriolis Effect) and water density. Ocean water moves in two directions: horizontally and vertically.

What is atmospheric circulation system?

atmospheric circulation any atmospheric flow used to refer to the general circulation of the Earth and regional movements of air around areas of high and low pressure. On average this circulation corresponds to large-scale wind systems arranged in several east–west belts that encircle the Earth.

What drives the movement of polar cells?

Warm moist air from the tropics gets fed north by the surface winds of the Ferrel cell. This then meets cool dry air moving south in the Polar cell. The polar front forms where these two contrasting air mass meet leading to ascending air and low pressure at the surface often around the latitude of the UK.

What is a cause of atmospheric circulation quizlet?

The uneven heating of the Earth’s surface and the Coriolis Effect is what causes atmospheric circulation. The warm air rises and the cool air sinks. A convection current results from the difference in air density. Circulation is further moved by the deflection of moving air and water due to the rotation of the Earth.

What happens if ocean circulation stops?

If this circulation shuts down it could bring extreme cold to Europe and parts of North America raise sea levels along the U.S. East Coast and disrupt seasonal monsoons that provide water to much of the world the Washington Post said.

What might happen if ocean water stopped circulating around the world?

If it continues to slow that could have profound consequences for Earth’s inhabitants. Studies suggest it would mean much colder winters and hotter summers in Europe changing rainfall patterns in the tropics and warmer water building up along the U.S. coast that can fuel sea level rise and destructive storms.

What is the role of the Coriolis effect in controlling ocean and atmospheric currents?

The Coriolis effect describes how Earth’s rotation steers winds and surface ocean currents (Figure below). Coriolis causes freely moving objects to appear to move to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. … As wind or an ocean current moves the Earth spins underneath it.
