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.
The named layers of the atmosphere apply only to the measured temperature profile, because their definition relies on the presence of inversions. A multi-layered model of a greenhouse atmosphere will produce predicted temperatures for the atmosphere that decrease with height, asymptotically approaching the skin temperature at high altitudes.

There is also a higher risk of sunburn due to the reduced blocking of ultraviolet by the thinner atmosphere. [50] [51] The amount of UVA increases approximately 9% with every increase of altitude by 1,000 metres (3,300 ft). [52] Symptoms of sunburn include red or reddish skin that is hot to the touch or painful, general fatigue, and mild dizziness.
An idealised view of three pairs of large circulation cells. Atmospheric circulation is the large-scale movement of air through the troposphere, and the means (with ocean circulation) by which heat is distributed around Earth. The large-scale structure of the atmospheric circulation varies from year to year, but the basic structure remains ...
Cutaneous respiration, or cutaneous gas exchange (sometimes called skin breathing), [1] is a form of respiration in which gas exchange occurs across the skin or outer integument of an organism rather than gills or lungs. Cutaneous respiration may be the sole method of gas exchange, or may accompany other forms, such as ventilation.
Hadley cells transporting heat and humidity from the Tropics to Mid-latitudes. In the region called the Horse latitudes, between 30 and 35 degrees of latitude North or South, there is a series of semi-permanent anticyclones on the downward side of the Hadley cell of the general atmospheric circulation.
“Holding yoga poses causes your muscles to propel the circulation of lymph (which circulates immune cells throughout the body), and in the same way, blood circulation increases, as does ...
As the sun does not heat the Earth evenly, there is a temperature difference between the poles and the equator, creating air masses with more or less homogeneous temperature with latitude. Differences in atmospheric pressure are also at the origin of the general atmospheric circulation while the air masses are separated by ribbons where ...
