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

In the middle cells, which are known as the Ferrel cells, air converges at low altitudes to ascend along Polar cell. 2020-08-17 · Global atmospheric circulation - Polar, Ferrel and Hadley cells The movement of air across the planet occurs in a specific pattern. The whole system is driven by the equator, which is the hottest Global winds blow in belts encircling the planet. The global wind belts are enormous and the winds are relatively steady. These winds are the result of air movement at the bottom of the major atmospheric circulation cells, where the air moves horizontally from high to low pressure. GLOBAL CIRCULATION OF THE ATMOSPHERE (2004) BY TAPIO SCHNEIDER AND ADAM SOBEL AFFILIATIONS: SCHNEIDER—California Institute of Technology, Pasadena, California; SOBEL—Columbia University, New York, New York CORRESPONDING AUTHOR: Adam H. Sobel, Department of Applied Physics and Applied Mathematics, and Department of This is a graduate-level textbook on the global circulation of the Earth's atmosphere--the large-scale system of winds by which energy is transported around the planet, from the tropical latitudes to the poles. Written by David Randall, one of the world's foremost experts on the subject, it is the most comprehensive textbook on the topic.
Global Physical Climatology is an introductory text devoted to the fundamental physical principles and Chapter 6 Atmospheric General Circulation and Climate.
This planet has an exact nonlinear equilibrium solution for the flow of the atmosphere, characterized by: 1. Every column is in radiative-convective equilibrium, 2. Wind vanishes at planet’s surface 3. Horizontal pressure gradients balanced by Coriolis accelerations 8 UPDATE: I'm making materials available for all of my lectures on my website (melstrong.org) for either those bored folks stuck at home due to the virus or te Atmospheric circulation occurs in the atmosphere, and is an essential part of How the Earth System Works.
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.
Figure 7p-1: Simplified one-cell global air circulation patterns. As described in the diagram above, surface air flow is from the poles to the equator. When the air reaches the equator, it is lifted vertically by the processes of convection and convergence. When it reaches the top of the troposphere, it begins to flow once again horizontally.
The atmosphere is redistributing its heat content such as to transfer heat poleward. The motions of the atmosphere that accomplish this transfer are largely
Global atmospheric circulation creates winds across the planet as air moves from areas of high pressure to areas of low pressure.

The air at the ITCZ (Inter Tropical Convergence Zone) upsurges because of convection caused by high insolation and low pressure is generated. The winds from the tropics join this low-pressure zone. The general circulation of the atmosphere is driven by spatial inhomogeneities in input of solar radiation and fluxes to/from the ocean. The atmosphere responds to these inhomogeneities by transporting latent heat (LH) and/or dry static energy (DSE) from the regions with an excess in energy (e.g. the tropics) to regions of deficit in energy (e.g.
A general circulation model (GCM) is a type of climate model.It employs a mathematical model of the general circulation of a planetary atmosphere or ocean. It uses the Navier–Stokes equations on a rotating sphere with thermodynamic terms for various energy sources (radiation, latent heat). The global atmospheric circulation model is a simplified version of how air currents in the atmosphere move.
