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 ...
Lake-effect rain forms in a similar way to lake-effect snow: cold air moves across the relatively warmer waters of lakes, thereby creating a sharp drop in temperature from the lake surface through the first several thousand feet in the atmosphere (the temperature gradient is known as the "lapse rate"), and then it precipitates the moisture over ...
Lake stars are rather common in Alaska and around the Great Lakes, where conditions can be extremely cold. For lake stars to form, it is believed that a thin layer of ice needs to be present with ...
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.
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 ...
At the same time, residents on the west shore will watch the lake recede far away from them. This phenomenon is what meteorologists call a 'seiche.' Witnessing a seiche is like looking at the ...
ST. JOSEPH, Mich. – On Sunday, a video captured massive waves crashing on Lake Michigan amid freezing temperatures and gusty winds. Temperatures near St. Joseph, where the footage was taken ...
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.
