About This Document

This article explains the global patterns of atmospheric circulation and precipitation distribution. It discusses the model of three-cell and the role of systems of global pressure in precipitation distribution. The article also explains the impact of the movement of the convergence zone on seasonal precipitation patterns.

Global Patterns of Atmospheric Circulation and Precipitation Distribution_1
1ANSWER 1:The global patterns of the heating of atmosphere and circulation are relied on the model of three-cell that insists that there is the existence of three cells among the poles of the earth and the equator which regulates the behavior. These cells are known as the polar cells that operate among the latitudes of 60o and 90o. Further, the Ferrel cell operates among the latitudes of 30o and 60o and Hadley cell works among the latitudes of 0o and 30o (Shepherd, T. G. 2014). Moreover, the Hadley cell is mainly responsible for the winds of the trade which commence withthe rising of warm air at the equator in the areas of reduced pressure up to the latitude of 30o untilit sinks in the area of increased pressure. The polar cell is basically responsible for the easterlies of polar, rises of warm air and it further shifts to the high altitudes where the frosty air sinks because of high pressure (Bonan, G. 2015). Furthermore, the Ferrel cell is very complex, and it has the rising of warm air at the high altitudes which are near to the cooling and polar cell, and it then shifts to the low latitudes and sinking in the areas of high pressure in the low latitudes closerto the Hadley cell.In the tropics, the high precipitation is reasoned by warm air from the converging of hemispheresin the convergence zone of the inter-tropic and the ascent of the air because of reduced pressure which gives rise to the convection in the climate (Kikuzawa et al., 2013). Further, high precipitation in the temperate zone takes place as an outcome of a various number of factors, including warm, cold and stationary fronts along with the systems of low pressure. The low precipitation in the tropical zone occurs as an outcome of warm, prevalent winds which are beingencumbered by the ranges of a mountain as the mountains impose the moisture in winds in order to come down on the size of the mountain which is clotting the winds as the rain. And this recessthe another side with the reduced precipitation.
