PPT-Local Winds

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 . 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, . . Rashed. Shamsa. . Saif. 11.57. Impact wind on navigation. The wind in the coastal population in particular note of the past moved them to codes and experiences, to relate the reasons for travel, cruises, and trading sailors books transferred to them knowledge about the nature of the wind and coasts, coral reefs and some of the features of land, and stars a big role in determining the terrain..

When you open the valve on a bicycle tube, the air rushes out.. 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.. 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.. 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…. 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..
