Lake-effect snow - Wikipedia
A cold northwesterly to westerly wind over all the Great Lakes created the lake-effect snowfall of January 10, 2022. Lake-effect snow is produced during cooler atmospheric conditions when a cold air mass moves across long expanses of warmer lake water.
What is a Lake Effect Snow? - National Weather Service
Lake Effect snow occurs when cold air, often originating from Canada, moves across the open waters of the Great Lakes. As the cold air passes over the unfrozen and relatively warm waters of the Great Lakes, warmth and moisture are transferred into the lowest portion of the atmosphere.

What Is Lake Effect Snow? | NOAA SciJinks – All About Weather
Dec 5, 2024 · Lake effect snow forms when cold, below-freezing air passes over a lake’s warmer waters. This causes some lake water to evaporate and warm the air. Then, the moist air moves away from the lake.
Thermodynamics & Ice Microphysics of Lake Effect Snow
4 days ago · Lake-effect snow gives us a great opportunity to examine multiple forcing functions working together to create heavy snowfall. Large-scale forcing (vorticity advection aloft) can destabilize the atmosphere by cooling the upper levels and raising the level of the capping inversion. Also, as indicated in the image below, frictional convergence ...
