I pointed out the large sea-level anomalies in the Indian Ocean at the beginning of this presentation. Iíll discuss this in more detail now. A Quicktime movie that is available separately shows the Indian Ocean fluctuations more clearly, but the figures below summarize it. Sea-level anomalies in the eastern Pacific began to move westward from the coast of South America in September. Shortly after this, sea-level increased suddenly and moved eastward again, indicating another Kelvin wave. At the same time, large sea-level anomalies developed in the Indian Ocean and began to move westward. By the end of 1997, sea-level in the southwestern Indian Ocean was as anomalously high as it was in the eastern Pacific. What was happening?
