PPT-Global and Local Winds

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. Remember…. Local means the area around a particular location. . We learned that wind forms because of uneven heating on Earths surface and air pressure. . Sea Breezes. Sea breezes occur near shorelines. . 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.. Objective. Reconcile the . conflicting evidence of the meridional westerly wind shift during the Last Glacial Maximum (LGM) indicated . by proxy-records from the . atmosphere . and . ocean. Approach. Local algebraic approximations. Variants on Taylor series. Local-Global approximations. Variants on “fudge factor”. Local algebraic approximations. Linear Taylor series. Intervening variables. Transformed approximation. G. VanNada. What are they?. Tropical cyclones that cross the subtropical ridge axis into the Westerlies recurve due to increased westerly flow. The winds are predominantly from the southwest in the Northern Hemisphere and from the northwest in the Southern Hemisphere. Earth/Space. S.W.B.A.T.. Explain why Earth receives different amounts of solar energy at different latitudes. Discuss the . Coriolis. effect. Identify and locate the doldrums, trade winds, prevailing .

When you open the valve on a bicycle tube, the air rushes out.. i. Winds are created by. ….. • . Heating the air, decreases pressure (warm. air rises creating a low pressure). • Cool air rushes into replace the warm air. (cooler dense air, produces high pressure). 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. 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…. Lecture 10: Local Winds. ATMO 102 Pacific Climates and Cultures. Large and Small Scale Winds . Macroscale Winds. Planetary: Westerlies, trade winds. Synoptic: Cyclones and anti-cyclones, Hurricanes (weather map size). 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.. April 19 and 20, 2018. Mark A. Bourassa. 1.
