Go to this website and choose images would show and El Niño and I La Niña conditions. Once you have done this, explain what conditions constitute at both situations. What are the consequences for the Eastern and Western Pacific during both of these conditions? Be sure to include the images you have selected with your answer.

Why is the El Niño also called the Southern oscillation?

Now find an image which shows the wind conditions along the surface of the Pacific during these two phenomena. Then find another image which shows the sea surface height anomaly during an El Niño event. Now, once you have done this, explain what is meant by anomaly.

Please include references and answer all questions.
