What air pressure systems are anticyclones associated with What air pressure systems are cyclones associated with Do Now What air pressure systems are anticyclones associated with Highs. Chapter 8. 1. Class #5 Tuesday, July 13, 2010. Air pressure and winds. Chapter 8. 2. Class #5 Tuesday, July 13, 2010. Atmospheric Pressure. What causes air pressure to change in the horizontal?. Why does the air pressure change at the surface?. Mrs. Wharton’s Science Class. Wind. The horizontal movement of air from an area of high pressure to an area of lower pressure.. All winds are caused by differences in air pressure. Differences of air pressure are caused by unequal heat . 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.. Defined as the force exerted on you by the weight of tiny air . particles . in . the atmosphere per unit area.. Earth’s atmospheric pressure = 14.7 pounds per square inch OR 1 kilogram per square centimeter. i. What causes wind? . Caused by a difference in air pressure due to. unequal heating of the atmosphere.. Winds are created by. ….. • . Heating the air, decreases pressure (warm. air rises creating a low pressure). 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.

Hurricane Structure. Category 5? typical gusts over open flat land of more than 280km/h. These winds correspond to the highest category on the Beaufort Scale. Extremely dangerous with widespread destruction. One of the Global . Winds. - A . current. is a flow of air or water in a certain direction.. Global . Winds. Winds move from areas of . high. pressure to . low. pressure.. You might expect them to move straight from the poles (high pressure) to the equator (low pressure)but…. Local winds are caused by the movement of air between low-pressure and high-pressure systems within small areas. As there are so many different types of winds, each one takes on a unique form. Local winds frequently have a significant impact on climate in local regions, so it is critical to understand what causes them.. Lucrezia Ricciardulli, Thomas Meissner, Frank Wentz.
