PPT-Global Winds What is wind?

Wind is the movement of air caused by an uneven heating of the Earths surface What HEATS EARTHS SURFACE Heat from the sun heats the surface of the Earth This heat arrives to Earth in the form of radiation. 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 . The Earth is Spinning…. Because Earth spins, winds and water appear to be deflected in a curved motion. This is called the Coriolis Effect. Which way do things. not connected to . Earth get deflected . 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.. October 17, 2012. National Weather Service. North Platte, NE. http://www.weather.gov/lbf. Email: . w-lbf.webmaster@noaa.gov. Phone: 308-532-4936. Decision Support Briefing. Highlights. What. Where. 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. 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. 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.. 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.. Lucrezia Ricciardulli, Thomas Meissner and Frank Wentz. Remote Sensing Systems, Santa Rosa, CA, USA. IOVWST Meeting, April 2018 . Barcelona, Spain. Acknowledgements: This work is supported by the NASA OVWST and SMAP Science. 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 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). 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…. air.  or other gases relative to a earth’s surface. . Global winds resulting from the difference in absorption of solar energy between the climatic zones on earth. . Winds . occur on a range of scales, from thunder storms where flows lasting tens of minutes, to local breezes generated by heating of . 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..
