General Circulation • The worldwide system of winds, which transports warm air from the equator where solar heating is greatest towards the higher latitudes, is called the general circulation of the atmosphere, and it gives rise to the Earth's climate zones. Clearly, the Hadley cell is not zonally symmetric. Studies of the General Circulation of the Atmosphere with a Simplified Moist GCM Author: Dargan M. W. Frierson Last modified by: Dargan Frierson Created Date: 10/15/2009 12:03:51 AM Document presentation format: On-screen Show (4:3) Company: University of Washington Other titles Direct thermal cell F F C C t t+! Atmospheric circulation is driven by two processes: *Upper atmosphere: subsolar-to-antisolar (SS-AS) circulation cell *Lower atmosphere: retrograde superrotating zonal (RSZ) flow The RSZ has constant direction from the upper atmosphere to the surface (Counselmann et al., 1980) and maximum momentum per unit volume near 20 km (Schubert, 1983). 3 Zonal Asymmetry - The Walker Circulation. Circulation of the Atmosphere - . Temperature profile. A climate model is usually a kind of the atmospheric general circulation models which simulate the physical and dynamical processes of the atmosphere (and oceans in some models) by solving relevant equations describing these processes. Chapter 5: The atmosphere in motion: winds, weather, and the general circulation of the atmosphere 5.1 The forces that drive atmospheric motion If we look at the atmosphere at the molecular scale (10-10 m), we see individual molecules travelling at the speed of sound (~400 m s-1), until they bounce off another air molecule or a solid surface.
