What type of clouds usually accompany lake effect snow?
What type of clouds usually accompany lake effect snow? Northern or westerly winds blow over the lakes' surface, picking up heat and water vapor that produce warm columns of air known as “thermals.” Those columns then cool down and condense into cumulus clouds, aligning in the direction of the prevailing wind over the lakes' surface.
Does lake effect snow occur around other areas besides the Great Lakes?
Worldwide some locations that get substantial lake-effect snows include Japan, the Korean Peninsula, Scandinavia off the Gulf of Bothnia and the Gulf of Finland, and Canada when cold air passes across Hudson Bay, the Gulf of St.
What is the lake effect snow paradox?
The climate around Lake Superior is colder than that around other Great Lakes, which makes it more able to support snowfall for a longer period of time, even when temperatures warm. Eventually, though, as temperatures continue to rise, lake effect snows turn into rain.
Can lake-effect snow happen on small lakes?
Lake-effect snow can form on small lakes just as it does in the Great Lakes. Salt Lake City, Fort Worth and Carson City, Nevada have all had bouts of snow from lakes. Inland lake-effect and ocean-effect doesn't just occur in the United States.
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.
How rare is lake effect snow?
Lake Effect Snow (LES) is very common across the Great Lakes region during the late fall and winter. LES occurs when cold air, often originating from Canada, moves across the open waters of the Great Lakes.
What is the wind direction for lake effect snow?
As mentioned above, for the Great Lakes to produce lake effect snow, a wind direction somewhere between north and northwest is generally the most favorable.
