    Lake-effect snow is produced during cooler atmospheric conditions when a cold air mass moves across long expanses of warmer lake water. The lower layer of air, heated up by the lake water, picks up water vapor from the lake and rises up through the colder air above; the vapor then freezes and is deposited on the leeward shores. The same effect also occurs over bodies of salt water, when it is termed ocean-effect or bay-effect snow. The effect is enhanced when the moving air mass is uplifted by t

    Some key elements are required to form lake-effect precipitation and which determine its characteristics:instability, fetch, wind shear, upstream moisture, upwind lakes, synoptic -scale forcing, orography/topography, and snow or ice cover.

    Cold winds in the winter typically prevail from the northwest in the Great Lakes region, producing the most dramatic lake-effect snowfalls on the southern and eastern shores of the Great Lakes. This lake effect results in much greater snowfall amounts on the southern and eastern

    The southern and southeastern sides of the Great Salt Lake receive significant lake-effect snow. Since the Great Salt Lake never freezes, the lake effect can influence the weather along the Wasatch Front year-round. The lake effect largely contributes to the 55–80 inches annual snowfall amounts recorded south and east of the lake, and in average snowfall reaching 500 inches in the Wasatch Range. The snow, which is often very light and dry because of the semiarid climate, is referred to as ...

    Lake Winnipeg, Lake Manitoba and Lake Winnipegosis in Manitoba historically have seen lake-effect snow as early as late October, and it is common throughout early to mid-November. Towards the end of November, the lakes sufficiently cool and begin to freeze, ending the lake-effect snow. A brief period of lake-effect snow is also common near Great Bear Lake and Great Slave Lake in the Northwest Territories during early winter; the lake-effect season for both lakes is very short, though. The lakes

    Lake-effect or sea-effect snow occurs in other countries, near large lakes or large sea areas. In Eurasia, it occurs in the regions of the Black Sea in Georgia, Romania, Bulgaria and northern Turkey, the Caspian Sea in Iran, the Adriatic Sea in Italy, the North Sea, the Irish Sea, the Aegean Sea, the Balearic Islands, and the Baltic Sea, as well as areas surrounding the Sea of Japan.
