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. The Earth's atmospheric circulation varies from year to year, but the large-scale structure of its circulation remains fairly constant.

In meteorology, air currents are concentrated areas of winds. They are mainly due to differences in atmospheric pressure or temperature. They are divided into horizontal and vertical currents; both are present at mesoscale while horizontal ones dominate at synoptic scale.

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.

Atmospheric circulation transports heat over the surface of the Earth that affects the water cycle, including the formation of clouds and precipitation events. The movement of air masses brings us our daily weather, and long-term patterns in circulation determine regional climate and …

2023年10月3日 · Global Atmospheric Circulation is the movement of air around the planet. It explains how thermal energy and storm systems move over the Earth's surface. Without the Earth’s rotation, tilt relative to the sun, and surface water, global circulation would be simple.

Air moves around the planet in a consistent pattern, called atmospheric circulation. Learn how convection and the spinning of the Earth create the prevailing winds.

2025年2月26日 · Air is constantly moving around Earth, a phenomenon known as atmospheric circulation. This circulation is the direct result of convection currents, which carry warm air from the region around the planet's equator towards poles. This occurs in atmospheric subdivisions known as wind cells.

2019年11月22日 · The global circulation of an atmospheric air current is the result of the Earth's temperature differences that create air pressure changes. The air and wind currents definition is air moving from high to low pressure areas.

Because the Earth rotates on its axis, circulating air is deflected toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere. This deflection is called the Coriolis effect. Click the image for a larger view. Coastal currents are affected by local winds.

2024年5月10日 · Factors Influencing Atmospheric Pressure and Air Currents. Barometric pressure is the force exerted by the weight of the atmosphere on the surface of the Earth. It is measured in pressure units such as millibars, kilopascals, or inches of mercury.
