Visible satellite loop on 13 Feb 2007
An interesting small scale phenomena occured over Lake Superior on Tuesday. The featured loop is of visible satellite images, notice the counter clockwise swirl? This swirl is a result of very cold air settling over the open lake water. The warmer and saturated air over the lake quickly rises forming shallow clouds and over time organizes into a circulation you can see on satellite. A larger time lapse can be found here. The COMET MetEd site has a much more detailed explaination of this phenomena.

Good = 30
Bad = 6
