What is an ENSO event and what conditions contribute to its occurrence? What effect does an ENSO event have on
the global environment, and how does it manage to have such far-reaching impacts? What will be an ideal response?
Concepts to Consider: ENSO events result from a weakening of the trade winds due to the
buildup of warm water in the western tropical Pacific, which then spreads to the East Pacific.
An ENSO event changes global atmospheric circulation patterns, resulting in unusual
weather in many areas. In addition, these events result in decreased productivity in ocean
areas off western North and South America and change the distribution of various marine
organisms in these areas.
