PPT-Weather patterns, Jet Stream, and Ocean Currents

Weather Patterns Weather patterns 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. 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. Vocabulary. Ocean Current. Coriolis Effect. Rip Current. Upwelling. Major Ocean Currents. An . Ocean Current. is a large volume of water flowing in a certain direction.. Wind-driven currents are called surface currents.. s. Warm. . currents flow . away. from the . equator.. Cold. currents flow . toward. the . equator.. Ocean Currents. Sun. Wind. Coriolis. Effect. Gravity. Factors Influencing Currents. Energy from the Sun heats the water.. I I Sampling sites on Kveisdalen bays; southeastern side. Two lagoons exist, one on the western one on the eastern side The climate is (Steffensen 1982). Fog frequent, especially annual mean precipita 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. What is a current?. 1. An Ocean Current . is a directed, continuous movement of ocean water generated by various forces.. 2. Currents are caused by various factors:. Temperature. Different salinity levels. 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. 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. wind, salinity, temperature, the Coriolis Effect, and gravitational pull.. 14)Ocean . currents flow in . predictable patterns. around the earth.. 15) Differences . in . density. and . temperature. causes currents..

This book belongs to: Ms. Ashmead Mississippi State Objective: 4c. Describe the causes and effects of heat transfer as it relates to the circulation of ocean currents, atmospheric movement, and global wind patterns (e.g., trade winds and the jet stream). Provide examples of how these global patterns can affect local weather. 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. The seasons are caused by the distance the Earth is . from . the Sun.. True or. False?. Seasons are due to the tilt of the Earth and differential heating of the earth’s surface.. False. Temperature. Mississippi State Objective:. 4c.
