(gravity, pressure gradient, and friction) push the air around. Two apparent forces . due to rotation (Coriolis and centrifugal). Large-scale flow is dominated by gravity/pressure and Coriolis … . 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, . away from the wind, the leeward side. In the Rockies, a foehn sometimes melts as much as two feet of snow overnight and is known as a chinook, the Indian word for snow eater. In South America, a west • . moving air. • horizontal movement of air from an area of high pressure to an area of low pressure. •winds can be . local or global. What is 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). The movement of air in a horizontal direction. What is wind?. The uneven heating of the Earth causes differences in air pressure.. What causes wind?. The Sun’s energy is more concentrated at the Equator and spread out more over the poles.. Y'heave. . ho! my lads, the wind blows free; . A pleasant gale is on our lee,.

By: Sean Meisner, Amanda Onwukwe, Arrian Bolden Pd:2nd. What Is Wind?. Wind: Is air moving across the surface of the Earth. Wind occurs because sunlight heats the earth’s atmosphere and surface unevenly.. 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..
