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 ...
Editor’s Note: Read the latest on the lake-effect snow here.This story is no longer being updated. As biting cold temperatures sweep across a large swath of the US, parts of the Great Lakes face ...
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 ...
The office said snow warnings and winter weather advisories would be in place until at least Monday for locations east and southeast of Lake Erie and Lake Ontario, and until Tuesday evening for ...
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.
A multi-day lake effect snow event off Lake Erie is ongoing, making travel "very difficult" throughout the Great Lakes region as a total of 3-12 inches of new snow was produced near Cleveland ...
