Global Atmospheric Circulation describes how air moves across the planet in a specific pattern. The Earth is surrounded by a thin layer of air called the atmosphere. The air in the atmosphere moves in response to differences in temperature at the equator (warm) and the poles (cold). Global circulation of the atmosphere Rossby waves in the westerlies, and frontal cyclones are the atmospheric responses to excess heating at low latitudes and excess cooling at high latitudes. The atmosphere is redistributing its heat content such as to transfer heat poleward. The motions of the atmosphere that accomplish this transfer are largely 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.

Global circulation is driven by pressure gradients in the atmosphere, the Coriolis force, and the friction of the atmosphere against the lithosphere. All of these may be summarized in a phenomenon … The general circulation of the atmosphere also sets in motion the marine water circulation which affects the climate of the Earth. The air at the ITCZ (Inter Tropical Convergence Zone) upsurges because of convection caused by high insolation and low pressure is generated.

Air in the equatorial regions is lighter than at the Poles, and therefore must rise. Mass conservation implies that air at low level must flow toward the Equator, while

This global circulation, driven by trade winds in tropical regions, has a well-defined organisation in each hemisphere: three convective cells in the meridian planes are associated with five winds along parallels, the weak eastern equatorial current in the vicinity of the equator and at low altitude, and in each hemisphere two westerly winds, the polar jet stream at a latitude near ±60° and Benna et al. analyzed atmospheric measurements collected by the Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft as it repeatedly dipped into the red planet's upper atmosphere. Combining multiple observing modes allowed the authors to derive wind speeds and map the global circulation of the atmosphere at altitudes of ∼150 kilometers. Global circulation is driven by pressure gradients in the atmosphere, the Coriolis force, and the friction of the atmosphere against the lithosphere.

The Northern and Southern Hemispheres each have three air circulation cells. These cells help distribute heat and air across Earth. Each cell is like a wide belt

The global pattern of atmospheric circulation on Mars shows many superficial similarities to that of Earth, but the root causes are very different.

In a situation such as this, the sun heats the entire surface, but where the sun is more directly overhead it heats the ground and atmosphere more.

1 The atmosphere circulates. The circulation is global in extent (see fig. 1.1). The circu- lating mass consists of “dry air” and three phases of water. Energy and momentum are carried with the air but evolve in response to various processes along the way.
