Lake-effect snow is produced during cooler atmospheric conditions when cold winds move across long expanses of warmer lake water, providing energy and picking up water vapor which freezes and is deposited on the leeward shores. The same effect over bodies of salt water is called _____-effect snow, where the blank would contain the description of the relevant body of water (e.g., ocean, sea, bay, sound). The effect is enhanced when the moving air mass is uplifted by the orographic influence of higher elevations on the downwind shores. This uplifting can produce narrow but very intense bands of precipitation, which deposit at a rate of many inches of snow each hour, often resulting in copious snowfall totals. The areas affected by lake-effect snow are called snowbelts. This effect occurs in many locations throughout the world but is best known in the populated areas of the Great Lakes of North America, and especially Western New York, northwestern Pennsylvania, northeastern Ohio, southwestern and central Ontario, northwestern and northcentral Indiana (mostly between Gary, IN and Elkhart, IN), and western Michigan. The Tug Hill Plateau of New York State has the most snow amounts of any non-mountainous location within the continental U.S., followed by the Upper Peninsula of Michigan, which can average over of snow per year.
