New paper out of the U-W and University of Minnesota-Duluth.
A wide temperature differential between water and air makes for a more stable atmosphere with calmer winds over the relatively cold water. However, as warming water closes the gap, as in Lake Superior's case, the atmosphere gets more turbulent.
"You get more powerful winds," Desai says. "We've seen a 5 percent increase per decade in average wind speed since 1985."
