GENERAL ATMOSPHERIC CIRCULATION A. PLANETARY PRESSURE BELTS 1. Equatorial calms (Doldrums) throughout the year a belt of low pressure surrounds the earth in the equatorial zone (except in the vicinity of the eastern Indian Ocean‚ East Indies and Australian region during the north hemisphere winter) most of air motion is vertical with light and variable winds having a slight westward drift 2. Subtropical calms or subtropical highs (Horse latitudes) characterized by high pressure

Essay Question: Only seeing general patterns can give us knowledge. Only seeing particular examples can give us understanding.” To what extent do you agree with these assertions? When I analyze this statement we have to fully understand what it means. I have to pay closer attention to the keywords. The main points in this statement are what I have to focus on to determine the answer to the question. General patterns are defined as things that people are familiar with and a form of something

General Pattern of Education in the USA The general pattern of education in the USA is an eight-year elementary school‚ followed by a four-year high school. This has been called 8—4 plan organization. It is proceeded‚ in many localities‚ by nursery schools and kindergartens. It is followed by a four-year college and professional schools. This traditional pattern‚ however‚ has been varied in many different ways. The 6—3— 3 plan consists of a six-year elementary school‚ a three-year junior high school

Global Atmospheric Circulation This essay will describe patterns of atmospheric heating and circulation. When the surface air reaches the Equator‚ it gets heated and rises to the top of the troposphere‚ where it spreads back toward the poles. When it gets to the poles‚ it descends back to the surface again to complete the cycle. The heat of the Sun causes water to evaporate from lakes‚ rivers and oceans‚ as well as from the leaves of plants called (transpiration). But this water

Explain the factors affecting the general atmospheric circulation (40 Marks) The variation in heating on the Earth’s surface from the sun is large enough for different patterns of pressure cells to form. With three cells in total‚ the first being the Hadley cell‚ devised in 1686 and revised in 1735‚ Hadley proposed that warm tropical air rises and spreads towards the poles at high altitudes‚ with a return flow towards the equator at low level. He added in 1735 the effects of the Earth’s rotation

The increase level of blood in the right atrium causes the tricuspid valve to open and drain the blood to the right ventricle. Pressure of blood in the right ventricle causes the pulmonic valve to open and non-oxygenated blood is directed to the pulmonary artery then to the lungs. The exchange of

The Components Of Earth’s Atmosphere And How Our Climate Is Affected By Volcanic Eruptions Introduction The atmosphere is all that lies between us‚ and the vast and unforgiving conditions of space. It absorbs energy from the sun‚ protects us from radiation‚ supports the cycle of water and other chemicals‚ and interacts with Earth’s magnetic fields to give us a climate capable of supporting life. Without it there would be no water‚ no air‚ no life. So we must protect it. But to protect

Atmosphere The atmosphere is the body of air which surrounds our planet. Most of our atmosphere is located close to the earth’s surface where it is most dense. The air of our planet is 78% nitrogen and just under 21% oxygen; the small amount remaining is composed of carbon dioxide and other gasses.It is a mixture of gases encircling the Earth and held by the Earth’s gravity. This invisible mixture of nitrogen‚ oxygen‚ argon‚ carbon dioxide‚ and water vapor protects the planet from harmful radiation
