A major winter storm hit parts of the U.S. North last week. Also last week, there was a full moon. That how NASA’s Suomi NPP satellite was able to capture this image of moonlight shining on snow, on December 14, 2016, in the area around the Great Lakes. NASA said:
The crisp, bright glow of city lights in Chicago and Detroit offers … evidence that the ground is covered in snow. If the white shade in the image were due to cloud cover, an overcast sky would likely obscure lights on the ground. Note how clouds blur the landscape in the bottom left part of the image.
Cloud streets appear above Lake Huron and Lake Superior. These parallel rows of clouds are created by cold, dry air blowing over a lake and accumulating water vapor.
Bottom line: Image from Suomi NPP satellite of snow from last week’s winter storm, illuminated by moonlight, in the region of the Great Lakes.
