The effect is similar to a storm surge like that caused by hurricanes along ocean coasts, but the seiche effect can cause oscillation back and forth across the lake for some time. In 1954, the remnants of Hurricane Hazel piled up water along the northwestern Lake Ontario shoreline near Toronto , causing extensive flooding, and established a ...
Waves can occur on the thermocline, causing the depth of the thermocline as measured at a single location to oscillate (usually as a form of seiche). Alternately, the waves may be induced by flow over a raised bottom, producing a thermocline wave which does not change with time, but varies in depth as one moves into or against the flow.
Lake stratification is the tendency of lakes to form separate and distinct thermal layers during warm weather. Typically stratified lakes show three distinct layers: the epilimnion, comprising the top warm layer; the thermocline (or metalimnion), the middle layer, whose depth may change throughout the day; and the colder hypolimnion, extending to the floor of the lake.

“During lake-effect snow, the weather can vary from bands of locally heavy snow with greatly reduced visibilities to dry conditions just a few miles away,” the National Weather Service in ...
Michigan, New York and other parts of the Great Lakes region remain on alert as lake-effect snow continues to create near-whiteout conditions, leading to dangerous traffic snarls in some areas ...
For lake-effect rain or snow to form, the air moving across the lake must be significantly cooler than the surface air (which is likely to be near the temperature of the water surface). Specifically, the air temperature at an altitude where the air pressure is 850 millibars (85 kPa ) (roughly 1.5 kilometers or 5,000 feet vertically) should be ...
