Unformatted text preview: For satellite pictures showing many different kinds of things, see: Review: Ocean currents What is the direction of the major ocean currents in the Atlantic and Pacific Ocean? Why do they have that direction? What is upwelling? What is the effect of upwelling on the ocean temperature in a region? How can a wind parallel to a coastline produce upwelling? What is an Ekman spiral? Is the typical ocean temperature warm or cold by the coast of Peru? Why is the Pacific Ocean so warm by Indonesia? Review What is the trigger that starts warm water sloshing eastward along the equatorial Pacific? What are conditions in the Pacific like during El Nio? During La Nia? How does the atmosphere above the Pacific Ocean respond to the oceans temperature changes? How often do El Nios occur? Give examples of climatic effects associated with El Nio and La Nia....
