Wind Currents Pdf Wind currents are caused by uneven heating of the earth's surface by the sun. near the equator, warm air rises and moves towards the poles, where it cools and sinks at around 30 degrees north and south latitude, creating high pressure zones. Learn about how the sun's energy drives convection to create winds and currents, and explore the impact of convection in air and water. discover why the earth's uneven warming causes wind patterns, and delve into ocean currents and coastal temperatures.
Wind Driven Currents Powerpoint Ppt Presentations Wind Driven Learn about convection, wind patterns, ocean currents, and the coriolis effect. a middle school presentation on climatic interactions. Surface currents of the oceans are driven by climatic winds and modified by the presence of landmasses. water movements created by the ekman transport of surface waters would lead to the formation of convergences and divergences. It explains that waves are caused by wind transferring energy to water over fetch. it also describes how tides are caused by gravitational forces from the moon and sun, and defines spring and neap tides. One way scientists use technology to predict an el niño is with a network of buoys operated by the national oceanic and atmospheric administration (noaa). the buoys are located along the earth’s equator record data about surface temperature, air temperature, currents, and winds.

Cold currents are shown in blue; warm currents are shown in red. * * * figure 7.32: in diagram (a), under ordinary conditions higher pressure over the southeastern pacific and lower pressure near indonesia produce easterly trade winds along the equator. Wind spirals away from high pressure in a clockwise direction and spirals toward low pressure in a counter clockwise direction. but the wind is constantly wanting to turn to the right because of the coriolis effect. Currents carry more energy than winds. florida–gulf stream current system. Gradual buildup of a geostrophic current: n.hem.: low lat. easterly winds, mid lat. westerlies => converging ekman transport & high sea level (sl) at ~30°n => geostrophic currents. with eastern and western boundaries, ocean circulation forms large clockwise or anticlockwise cells = gyres.
