Snow over the Great Lakes
Western Michigan, United States
|The Great Lakes create their own snowfall when cold air picks up water vapor. As the winds blow south, this water vapor falls back to Earth as snow, an occurrence known as the "lake effect." The cities downwind from the Lakes often receive huge snowfalls. Here, snow thickens over western Michigan.
