How does wind direction affect lake effect snow?
How does wind direction affect lake effect snow? The fetch is important in that a longer fetch will provide more fuel, or water vapor, for the development of heavier lake effect snow. For example, a north wind will produce a narrow band of very heavy snow to the south of Lake Michigan, while a (cold) west wind will produce multiple weaker bands to the east.
Why are lakes so calm in the morning?
During the early morning hours, the land and the water start out at roughly the same temperature. On a calm morning, a given pressure surface will be at the same height above both the land and water. A few hours later, the sun's energy begins to warm the land more rapidly than the water.
