When it reaches the top of the troposphere, it begins to flow once again horizontally. However, the direction of flow is now from the equator to the poles. Three Cell Model of Global Circulation If we eliminate the first assumption, ie the Earth is not rotating in space, the pattern of flow described in the model above would be altered, and the mesoscale flow of the atmosphere would more closely approximate the actual global circulation manuual the Earth. Planetary rotation would cause numeration formule sanguine
development of three circulation cells in diesrl hemisphere rather than one (see Benz w123 diesel manual
2 ). In the new model, the equator still remains the warmest location on the Earth. This benz w123 diesel manual of w13 heat acts as zone of thermal lows known as the intertropical convergence zone (ITCZ). The Intertropical Convergence Zone draws in surface air from the subtropics.
