PPT-Summary of Winds and Currents from Satellite Meeting

April 19 and 20 2018 Mark A Bourassa 1 Ernesto Rodriguez 2 and Sarah Gille 3 Center for OceanAtmospheric Prediction Studies and Department of Earth Ocean and Atmospheric Science Florida State University. Early ocean studies. For much of human history, knowledge of the ocean and its currents was not recorded for many reasons - most sailors could not write and information was passed orally.. European nations began systematic ocean explorations but kept information secret between the 15. Currents. Ocean water contains streamlike movements of water called . ocean currents.. Currents can travel extremely far. In ancient times, currents were largely responsible for any human travel across the oceans. It is believed that currents carried the ancient Peruvians over 6,000 km across the south pacific to Polynesia. . Wind-driven surface currents. Figure 7-4. Ocean Circulation Animation. Ocean Currents. Ocean currents- are stream-like movements of water. Ocean currents affect our weather and climate. 2 Types:. 1) Surface Currents. Global winds. Ocean Currents . Local winds. Coriolis Effect. Because the Earth rotates, and consists of a mixture of land and sea, the . Coriolis Effect . exists. The . Coriolis Effect. is the movement of particles (such as air) to the right in the Northern Hemisphere. http. ://oceanexplorer.noaa.gov/edu/learning/player/lesson08.. html. . . I. . Ocean . currents = Stream like movements of water. A. Surface currents. = occur near or at the surface of the ocean. Can reach 100 m deep or deeper. The water in the ocean moves in giant streams called currents.. Scientists place ocean currents into two major categories: surface currents and deep currents.. Surface . Currents. Ocean currents that occur at 328 feet deep or above. The Answers. Oceanography 2014. 1. Chronometer. Accurate maritime clock. Invented by John Harrison 1735. 2. What contributions did the Chinese make to sailing?. MOST IMPORTANT = compass. 3. Latitude and Longitude in the N Hemisphere. Weather Patterns. Weather pattern’s are described as prolonged temperature changes over a specific area for example seasons.. Weather patterns can also be described as a period for which natural disasters are prevalent ex. Hurricane season, tornado season, blizzards. Earth/Space. S.W.B.A.T.. Explain how winds and the . Coriolis. effect influence surface currents. Discuss the temperatures of coastal waters. Describe density currents and how they affect Earth. Surface Currents. How do different currents form. What is upwelling. What do ocean currents transfer. Predict. T F. Ocean currents are always cold. C. ontinents affect the direction of currents. Currents only flow near the surface of the ocean. 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…. Ocean Current Layers. Surface Currents. . – . top . 10% of the ocean; upper 400 m. Deep Currents . – lower 90% of the ocean. Properties . of . Ocean . Water . How they impact ocean currents. Temperature. 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..
