Sc260 Ecology

The global patterns of atmospheric heating and circulation are a real complex phenomenon. Many factors contribute to maintaining a balance at bottom the different regions to insure the proper environment and seasons. Energy from the lie heats the entire Earth, but this heat is distributed unevenly. The tropics receive more than heat radiation than they emit, while the polar regions emit more heat radiation than they receive. Without this heat transfer occurring, the tropics would backup larnting hotter and while the poles would keep getting colder. This heat mental unsoundness is very important in maintaining an ecological balance in spite of appearance the Earth and drives the circulation of the atmosphere and oceans. (Schlanger, 2004)

Since the Earth is constantly rotating, this al piteous-pitcheds for three circulation cells in each hemisphere. These three cells are known as the Yankee and southern trade winds, the westerlies and the polar easterlies. Each of these cells has different climates associated with them and in conclusion depends on each other to maintain those specific climates.

The blue and southern trade winds are located directly wedlock and south of the equator, where they meet. Since they meet, this causes the air to rise. As the rising air cools, clouds and fall develop.



This rise and fall of the air is called a Hadley cell. (Benders-Hyde, 2008)This Hadley cell results in bands of cloudy and rainy weather near the equator causing tropic conditions in temperate zones. This same modestness, but in reverse, is the reason you get low precipitation in the same prevalent latitudes.

Global atmospheric circulation models show how air near the equator tends to rise, overdue to the temperatures being higher than the surrounding topics. This leads to high instability and low pressure, acting like a conveyer belt for water supply and creating high levels of precipitation. Because of the Earths tilt, the area over which low pressure can sit changes from season to season. (Clift & Plumb, 2008)...If you want to get a full essay, order it on our website: Orderessay
