Description:

The paper explains that the weather patterns we are so vulnerable to come from the interaction of three general zones, the Hadley, Polar, and Ferrel cells, which consistently move and maneuver earth around the globe. The paper describes the impact of these three cells but points out that as they fluctuate annually, they are also threatened by global warming that has negatively impacted the natural ecology of the Earth.

From the Paper:

"The weather patterns of our Earth are regulated by a vast system of atmospheric conditions which force air and pressure up and down across the globe. The basic structure of the nature of atmospheric conditions comes from a familiar source, the sun; "The central feature of global weather is the redistribution of solar energy that falls unequally on Earth at different latitudes," (Manahan 2006:193). The sun heats up the earth's surface unevenly, causing mixed reactions between the warmer air of the tropics, which are closest to the sun at all times, and the cooler air of the icy poles. The earth moves hot and cold air around to mix them and keep temperature in check and regulate weather patterns. The three cells that dominate over atmospheric circulation have a fluid structure which does vary annually, yet generally stays similar in nature.
"The largest of the three cells and most forceful in climate conditions as we know it is the Hadley Cell. Located over the equator zones, this cell moves hot air u into the atmosphere from the earth's surface, for hot air always rises higher than cooler air. The excess energy caused by the warmth in the air near the equator causes that air to rise until it hits the troposphere, where it "cools by expansion and loss of water, then sinks again," (Manahan 2006:193). This motion of hot air rising, cooling, and sinking again results in a high pressure zone."
