Chalk up another effect of climate change: it’s getting windier over Lake Superior.
That is the conclusion of a study by scientists who have looked at the effects of increasing surface water temperatures in the lake and air temperatures over it. The water has warmed faster than the air, creating instability in the air mass that results in stronger winds.
“Less ice in the winter means stronger winds in the summer,” Dr. Desai said.
Ice coverage of Lake Superior has declined in recent decades, which means that the lake starts to warm sooner, becoming stratified. The earlier this stratification occurs, Dr. Desai said, the warmer the top layer gets in the summer.
Data from buoys and satellites showed that this warming outpaced that of the air above it. That means the thermal gradient between the two was reduced.
