This circulation occurs in ‘ cells ’. 588 views. Atmospheric circulation is the movement of air across the planet, and this occurs in a pattern. Changes to the Global Atmospheric Circulation as the climate changes. Preview. Livraison en Europe à 1 centime seulement ! Water vapor in the atmosphere increases with warming, especially over the oceans. Circulation in most other latitudes are dominated by westerlies with wave patterns. The global atmospheric circulation transports energy from the equatorial regions to higher latitudes through a poleward flow of high-energy and -entropy parcels and an equatorward flow of air with lower energy and entropy content. Terminology. 8 items. Join Pearltrees. Hadley circulation is a result of the temperature gradient that is caused by the spherical nature of Earth. tri-cellular … George Hadley ; The earth is warmed at the equator. Dominated by large-scale waver patterns (wave number 3 in the Northern hemisphere). The different cells help to determine the climate and winds at different latitudes. Have a look at the slideshow on the right for a simple explanation. Global Atmospheric Circulation describes how air moves across the planet in a specific pattern. label . THE GLOBAL MODEL OF ATMOSPHERIC CIRCULATION The details of the structure of the global model of the atmosphere can be found in the paper by Holloway and Manabe (1970). Therefore, a very brief description of the model is given here. Cool air sinks, creating a belt of high pressure. You need to get 100% to score the 10 points available. Global Atmospheric Circulation. Editors: L.M. The Coriolis Effect. Hadley Cell. Equatorial and tropical regions receive far more solar energy than the midlatitudes and the polar regions. All this activity is driven by absorbed sunlight and loss of infrared (heat) energy to space. The global atmospheric circulation patterns that are evident in the Earth's atmosphere are a product of the differential heating of the Earth. Author: Created by Bsnewbury. Global Atmospheric Circulation Energy from the Sun heats the entire Earth, but this heat is unevenly distributed across the Earth's surface. The atmospheric circulation must provide a poleward transport of energy . There are three cells in each hemisphere. The Intertropical Convergence Zone is an equatorial belt of low pressure.
