Snow water equivalent (SWE) is the depth of water that would result if the snow mass melted completely, whether over a given region or a confined snow plot, calculated as the product of the snow height in meters times the vertically-integrated density in kilograms per cubic meter.
In astronomy or planetary science, the frost line, also known as the snow line or ice line, is the minimum distance from the central protostar of a solar nebula where the temperature is low enough for volatile compounds such as water, ammonia, methane, carbon dioxide and carbon monoxide to condense into solid grains, which will allow their accretion into planetesimals.
The frost depth depends on the climatic conditions of an area, the heat transfer properties of the soil and adjacent materials, and on nearby heat sources. For example, snow cover and asphalt insulate the ground and homes can heat the ground (see also heat island). The line varies by latitude, it is deeper closer to the poles.
Without snow, the ground absorbs more heat, creating a warming feedback loop. This article originally appeared on USA TODAY: Snow depth tracker: See how much snowfall has hit the US Show comments
When snow is collected, the container is removed and replaced with a spare one. The snow is then melted while it is still in the container, and then poured into a glass measuring graduate. While the depth of snow is normally measured in centimetres, the measurement of melted snow (water equivalent) is in millimetres. [citation needed]
The U.S. record is 12 inches in a single hour. That happened in a lake-effect snow band east of Lake Ontario in Copenhagen, New York, on Dec. 2, 1966, according to a list of record snowfall rates ...
Snow Depth-This is a measurement from the snow surface to the ground in meters. It is commonly does over a large time span using immobile graduated stakes. Snow Water Equivalency - A measuring tool which represents the vertical depth of water that would accumulate in an area, if all the snow and ice were melted in that given area.
And here’s a fun fact from weather historian Christopher Burt: The greatest measured snow depth in the Northern Hemisphere was 466 inches (38.8 feet) in 1927 at Mt. Ibuki at an elevation of ...
