Lesson 3: El Niño and the Southern Oscillation (ENSO)

 http://www.learn-eo.org/lessons/l3/

 El Niño is one of the most famous phenomena in the ocean-atmosphere system. In the ocean it affects sea surface height and ocean temperature. In the atmosphere it affects the winds and transport of moisture. It therefore influences seasonal weather patterns in many regions of the world, and understanding how it develops can help us estimate the likelihood of floods or droughts in these areas. This lessons looks at the progression of El Niño across the Pacific Ocean and its turn back to La Niña, using the power of the global view made possible by satellite observations.
