PPT-Circulation Patterns, Currents, & Wind

Winddriven surface currents Figure 74 Ocean Circulation Animation Ocean Currents Ocean currents are streamlike movements of water Ocean currents affect our weather and climate 2 Types 1 Surface Currents. Susan Howard. Earth & Space Research. Basically – why and how the ocean and atmosphere MOVE!. www.ametsoc.org . There are many scales of motion: . From . BIG. . to . very small. Today – I will just cover the basic large scale, GLOBAL circulation.. 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.. The Earth is Spinning…. Because Earth spins, winds and water appear to be deflected in a curved motion. This is called the Coriolis Effect. Which way do things. not connected to . Earth get deflected . 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. 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.
