El Niño Information Sites
El Niño is an unusual warming of sea surface temperatures in the equatorial Pacific extending from the South American coast to the International Dateline. El Niño's occur approximately every two to seven years. Large El Niño's are thought to have an impact on the world's weather patterns. During larger El Niño's, Minnesota's winters have tended towards the mild side (with some exceptions). There is no significant connection between Minnesota's winter snowfall and El Niño. The intense El Niño of 1997-1998 is thought to be one of the most signficant of the century. To learn more about El Niño, see the informational sites listed below.
