摘要：

Mild winters and below-average annual maximum ice cover for the Laurentian Great Lakes occur during strong warm ENSO events. During the six strongest warm ENSO events since 1950 a Great Lakes winter severity temperature index and simulated annual maximum ice cover averaged 1.2 degrees C above and 15% below a 1950-1994 average, respectively. The observed differences between the average of the strong ENSO event years and the base period average are statistically significant.
