Ice Indicator: New Approach Reliably Predicts Great Lakes Ice Cover

Highly-localized and accurate Great Lakes ice cover forecasts have been demonstrated by researchers at the University of Michigan and their predictive modeling tool can be adapted for any geographic region.

The new approach can reliably predict months in advance whether ice will form in a given winter, as well as the timing of ice onset. Many previous efforts have focused on ice cover on the lake as a whole. By focusing on a small area, it is possible to find relationships between weather and local conditions that make ice formation possible, even in years when conditions are not supportive of lake-wide ice formation.
