PPT-Air Pressure and Wind

What is air pressure Air Pressure the force exerted by the weight of the air above it Why does the weight of the air not crush you The pressure is exerted in all directions not just down Ruler and newspaper demonstration. Coriolis. Effect. Air pressure differences cause the movement of air. Air moving parallel to the ground is called . wind. Air moving up or down is called a . current. Air generally moves from the poles to the equator, . 003: Lab 4. Chapter 4: 14ab, 15c. Chapter 5: 4abc, 10ab, 18. Chapter 6: 2ab, 7ab, 9acd. Chapter 7: 9ab. 4.14a,b. pg. 163. Isohyets: . . isopleths of rainfall. a). -same guidelines as all isopleths. Earliest use of wind power goes back to the development of sailing ships. Larger vessels built in the 19. th. century could extract as much as 10000 hp.. Stationary wind machines were later brought into practice.. atm. layers). _____rise in the global temperature due to an increase in carbon dioxide caused by human . activity (water cycle 2). _____ most energy in the atmosphere is transferred by this heat . process (.

Why Air Moves. Wind is created by differences in air pressure. Bigger difference = faster wind. Caused by unequal heating of earth. Air. The air by the equator is warm and rises. Low pressure. The air by the poles is cold and dense. Chapter 2.2 Guided Notes. What is Weather?. Weather is the condition of Earth’s atmosphere at a particular time and place.. What is Wind. ?. Wind is air moving across the surface of the Earth. It can move horizontally or parallel to the ground.. 3. H. 2. O part of constant. Chain Reaction Example. “M” is any other. m. olecule available for collisions. UNITS. Mixing ratio or mole fraction . C. X. . [mol mol. -1. ]. remains constant when air density changes. 19.1 Understanding Air Pressure. Don’t notice change in your day to day activities. Mostly cause-and-effect relationship. Air pressure causes wind. Wind brings change in temperature/humidity/precipitation. Warm-up What is weather? REMINDER – QUIZ CH.11 WEDNESDAY Chapter 12 Meteorology Causes of Weather Meteorology – the study of atmospheric phenomena such as fog, clouds, snow, rain, and lighting Weather It is caused by:. 1.Differences in . temperature. .. 2.Differences in . pressure. .. WIND. Wind is the . movement. of air.. It is caused by:. 1.Differences in . temperature. .. 2.Differences in . pressure. Sea and Land Breezes (Thermal Wind). Coriolis Force. Geostrophic Wind. Centrifugal Force & Friction. Gradient Wind. Surface vs Aloft Winds. Mountain Breezes. Katabatic Winds. Force: a quick lesson. Problem 6.11 (a, b). Mark all centers of High and Low pressure (and 2 locations where it might be off the map). Check surrounding isobars . Find 2 troughs and 2 ridges. Trough:. elongated region of low pressure. Wind is the movement . of air caused by an uneven heating of the Earth’s . surface.. What HEATS EARTH’S SURFACE?. Heat from the sun heats the surface of the Earth.. This heat arrives to Earth in the form of radiation..
