In the Great Lakes, water temperatures are roughly the same temperature from the surface to the bottom of the lake in spring and fall. During winter and summer, the water temperature from the ...
With Great Lakes water temperatures running 4-6.5 degrees above average, the arctic winds are picking up the warmth and moisture from the waters and transfer it into the lowest portion of the ...
The amount of raw sewage dumped into the waters was the primary focus of both the first Great Lakes Water Quality Agreement and federal laws passed in both countries during the 1970s. Implementation of secondary treatment of municipal sewage by major cities greatly reduced the routine discharge of untreated sewage during the 1970s and 1980s. [90]
It typically happens in the fall and early winter, before the lakes freeze, and is common in the Great Lakes region, according to the National Weather Service. Lake-effect snow happens when cold ...
The water surface's slow reaction to temperature changes, seasonally ranging between 32 and 55 °F (0–13 °C) around 1970, [35] helps to moderate surrounding air temperatures in the summer (cooler with frequent sea breeze formations) and winter, and creates lake-effect snow in colder months. The hills and mountains that border the lake hold ...
Lake-effect rain forms in a smilar 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 ...
On Jan. 1, the average for today is about 9%.” ... Seasonal outlooks this year forecast higher-than-average temperatures in the Great Lakes region and below-average ice.
While the lake is relatively warmer than the other Great Lakes, there is a thermocline, meaning that as a diver descends, the water temperature drops about 30 degrees Fahrenheit change (17 °C), requiring a wetsuit. [131] One estimate is that Lake Erie has a quarter of all 8,000 estimated shipwrecks in the Great Lakes. [131]
