Abstract
Mild winters and below-average annual maximum ice cover for the Lauren tian Great Lakes occur during strong warm ENSO events. During the six strongest warm ENSO events since 1950 a Great Lakes winter severity te mperature index and simulated annual maximum ice cover averaged 1.2 de grees C above and 15% below a 1950-1994 average, respectively. The obs erved differences between the average of the strong ENSO event years a nd the base period average are statistically significant.
