Global Air Circulation PatternsWe know so little about the place that has been our home for thousands of years. There are so many unseen functions of the planet Earth that have such strong influences on all aspects of the creatures which walk upon it. The forces of the air and atmosphere are some of the most influential on global weather patterns. Understanding the atmospheric conditions of the Earth gives us a glimpse into our own home which was previous unseen. These conditions rule our everyday lives, yet go largely unnoticed or completely understood by most of humanity. 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. Their interaction with each other affects the climate as well as individual weather patterns. Although they have been present since our existence on the Earth, these atmospheric conditions are not permanent. As they fluctuate annually, they are also threatened by human forces that have negatively impacted the natural ecology of the Earth.
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 pole

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. It also creates the Coriolis effect, or "The air in the Hadley cells does not move straight north and south, but is deflected by Earth's rotation and by contact with the rotating Earth […] which results in spiral-shaped air circulation patterns," (Manahan 2006:194). This circulation combined with hot air pressure can result in great weather instability in the region. Such patterns create the environment for large tropical storms and hurricanes as hot air cools and sinks with the warmer air. Yet as destructive as this force may be in terms of erratic weather patterns, it has also been the foundation of one of an extremely useful oceanic current system. According to research, "The movement of air in Hadley cells combined with other atmospheric phenomenon results in the development of massive jet streams that are in a sense, shifting rivers of air that may be several kilometers… READ MORE
