Abstract:
The term El Niño refers to abnormal and significant warm temperatures in a vast upper-ocean water body of the equatorial central to eastern Pacific oceans. It often has significant manifestations near the Peru coast where a few centuries ago, fishermen coined its name as they noted its full strength occurring almost always near the Christmas time. An El Niño event normally lasts over a year and is often followed by the so-called La Niña which is a cold anomaly lasting sometimes longer than El Niño. El Niño and La Niña often alternate and together form 2-7 year irregular cycles dominating the earth’s natural climate variability. They dramatically alter global weather activity patterns and thus have great global impacts. With a brief introduction of this widely known phenomenon, this talk will address the questions about the fundamental mechanisms that are responsible for the genesis of its ceaseless cycles and complexity. By using analogies to explain relevant math concepts, I hope to convey some findings from theoretical studies to delineate a hidden beauty residing in dynamics of the El Niño–Southern Oscillation (ENSO). I may also briefly discuss how understanding of El Niño and its strong global influences may have implications improving climate predictions.
