  1. Starter 11-6-13Compare and contrast El Nino/La Nina using a Venn diagram.

  2. Ocean Currents Video • http://www.youtube.com/watch?v=1ifoCIFKYXQ

  3. Coriolis Effect No Foldable – put in your journals; use markers or highlighters as needed

  4. Intro There are 3 major forces that determine how strongly the wind will blow and in what direction: • Pressure Gradient Force • push from high pressure to low pressure • Friction • CoriolisEffect

  5. Intro • named for, nineteenth century French engineer Gaspard C. Coriolis • Coriolis discovered that a force appears to be operating on any moving object situated on a rotating body, such as a stream of air traveling on the surface of a rotating planet.

  6. Coriolis Effect • caused by Earth’s rotation • appearance to the observer on Earth of the path of a moving object to deflect to the right in N. Hemisphere & to the left in the S. Hemisphere

  7. Coriolis Effect cont’d • also causes low pressure systems to rotate clockwise • high pressure systems to rotate counterclockwise

  8. Degree of deflection depends on how fast the winds are blowing and it’s latitude: • slower the wind speed, the less it will be deflected • faster the wind speed, the more it will be deflected • more deflection at the poles • less deflection at the equator

  9. Summary • From outer space it would appear the winds are moving in a straight line • Since you are on earth and it is rotating, it looks to you like the winds are curving • There really a change in motion, but that is ONLY because the target or frame of reference is rotating with the earth
