The 2024 ice season was the second time average ice cover across the Great Lakes did not reach 5%. The first time was in 2012, when it hit 4.8%. (The third lowest was 7% in 2002.)
Ice coverage for all of the Great Lakes combined was 23.21% – the highest since February 26, 2022, when it was 56.1%. At the beginning of this month, ice coverage was less than 2% across all the ...
Last year, ice coverage peaked at about 23% and by mid-February, ice only covered 7% of the lakes. Earth experienced its hottest year on record in 2023 , largely because of human-caused climate ...
Lake Superior's deepest point [4] on the bathymetric map. [1] Lake Superior has a surface area of 31,700 square miles (82,103 km 2), [7] which is approximately the size of South Carolina or Austria. It has a maximum length of 350 statute miles (560 km; 300 nmi) and maximum breadth of 160 statute miles (257 km; 139 nmi). [8]
Lake-effect snow is produced as cold winds blow clouds over warm waters. Some key elements are required to form lake-effect precipitation and which determine its characteristics: instability, fetch, wind shear, upstream moisture, upwind lakes, synoptic (large)-scale forcing, orography/topography, and snow or ice cover.
A warm start to the winter season has left the Great Lakes virtually ice-free and with their lowest ice cover to kick off a new year in at least 50 years.
The Laurentide ice sheet (LIS) was a massive sheet of ice that covered millions of square miles, including most of Canada and a large portion of the Northern United States, multiple times during the Quaternary glaciation epochs, from 2.58 million years ago to the present.
Great Lakes ice cover is off to a slow start in 2024. Unseasonably warm air temperatures are likely to blame. Great Lakes ice cover was at record low on Jan. 1, that could still change, but the ...
