Snowpack is an accumulation of snow that compresses with time and melts seasonally, often at high elevation or high latitude. [ 1 ] [ 2 ] Snowpacks are an important water resource that feed streams and rivers as they melt, sometimes leading to flooding.
All SNOTEL sites measure snow water content, accumulated precipitation, and air temperature. Some sites also measure snow depth, soil moisture and temperature, wind speed, solar radiation, humidity, and atmospheric pressure. These data are used to forecast yearly water supplies, predict floods, and for general climate research.
Height of snowpack (HS) is the total depth of the snowpack, measured vertically in centimetres from base to snow surface. Height of new snow (HN) is the depth in centimeters of freshly fallen snow that accumulated on a snow board during a period of 24 hours or some other, specified period.
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
Snow depth at Stryker Basin in the Whitefish Range was 50 inches, while Big Mountain's upper reaches still held 53 inches of snow. Overall, the Flathead Basin snowpack was 85% of normal on May 26 ...
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 ...
Depth hoar – Depth hoar comprises faceted snow crystals, usually poorly or completely unbonded (unsintered) to adjacent crystals, creating a weak zone in the snowpack. Depth hoar forms from metamorphism of the snowpack in response to a large temperature gradient between the warmer ground beneath the snowpack and the surface.
At ARAI Snow Resort in Niigata Prefecture, the snow depth was 17.26 feet (526 cm) on Jan. 31. Heavy machinery is used to clear a road as heavy snow falls across northern Japan, in the city of ...
