Great Lakes Ice cover

Lake Superior Ice Analysis

Lake Superior Ice Analysis



How does ice coverage on Lake Superior this year compare to last year?


The following satellite image was taken on Febuary 1, 2010. The image shows low level lake effect clouds over the eastern half of Lake Superior, and upper level clouds over western and central Lake Superior. What's significant about this image is that through the clouds, the lake appears to be mostly ice free.

Lake Superior ice coverage is much less than this time last year. The following image, taken on Feb 6, 2009, shows a much larger area of ice in Lake Superior.

Now the question is whether this year is significantly behind normal for ice coverage, or if last year had significantly more ice than normal. The following image is a stistical analysis of Ice cover for the Great Lakes, showing average ice cover for the week of Feb 1-7. Comparing the images shows that ice coverage on Lake Superior is behind normal for this year, and also that ice coverage last year was significantly above normal. Ice coverage, on average, peaks in early March for Lake Superior.

    Some time before, I needed to buy a house for my organization but I did not have enough cash and couldn't order anything. Thank goodness my comrade proposed to try to get the home loans at creditors. Hence, I did so and was satisfied with my sba loan.

    Andy, I used this information in my social studies lesson last week and the kids were FASCINATED by the photos. We had a great discussion and it really enhanced our study of Michigan's Great Lakes! Thank You!
