Global atmospheric circulation creates winds across the planet as air moves from areas of high pressure to areas of low pressure. It also leads to areas of high rainfall, like tropical rainforests, and areas of dry air, like deserts.
Air on the surface is pulled towards the poles, forming the warm south-westerly winds in the northern hemisphere and north-westerly winds in the southern hemisphere. These winds pick up...
Warm air rises at the equator and travels to around 30º North where it cools and sinks to the surface, before returning to the tropics. This movement is known as the Hadley cell. At the equator...
The air travels to around 30°, cooling as it moves. At around 30° the cooled air sinks back to Earth to create an area of high pressure. Air moves from this high-pressure area to the equatorial...
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 ecosystems.
Oct 3, 2023 · 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.

Jan 25, 2006 · The study of air transportation within the field of transportation geography and the larger discipline of geography is important as geographers use air transportation to help describe concepts such as connectivity and linkages, development patterns at various scales, and the global economy.
