The Canadian Arctic tundra is a biogeographic designation for Northern Canada's terrain generally lying north of the tree line or boreal forest, [2] [3] [4] that corresponds with the Scandinavian Alpine tundra to the east and the Siberian Arctic tundra to the west inside the circumpolar tundra belt of the Northern Hemisphere.
"Sugar snow" as a layer in a snowpack Depth hoar crystals, imaged with light and with scanning electron microscopy Sugar snow - panoramio. Depth hoar, also called sugar snow [1] or temperature gradient snow (or TG snow), [2] are large snow-crystals occurring at the base of a snowpack that form when uprising water vapor deposits, or desublimates, onto existing snow crystals.
The combination of density and low viscosity makes fresh layers of graupel unstable on slopes, and layers of 20–30 cm (8–12 in) or higher present a high risk of dangerous slab avalanches. In addition, thinner layers of graupel falling at low temperatures can act as ball bearings below subsequent falls of more naturally stable snow ...
Greenland ice sheet as seen from space. An ice sheet is a body of ice which covers a land area of continental size - meaning that it exceeds 50,000 km 2. [4] The currently existing two ice sheets in Greenland and Antarctica have a much greater area than this minimum definition, measuring at 1.7 million km 2 and 14 million km 2, respectively.
Rimed snow refers to snowflakes that are partially or completely coated in tiny frozen water droplets called 'rime'. Rime forms on a snowflake when it passes through a super-cooled cloud . Snowflakes that are heavily rimed typically produce very heavy and wet snow, with snow to liquid ratios in the 5-1 (i.e. five inches of snow per inch of rain ...
These walls sometimes expose layers that represent the glacier's stratigraphy. Crevasse size often depends upon the amount of liquid water present in the glacier. A crevasse may be as deep as 45 metres (150 ft) and as wide as 20 metres (70 ft) [2] The presence of water in a crevasse can significantly increase its penetration.
Welcome to ‘Snow Village’ in Chengdu- where snow is made of cotton balls, the ground is white sand, and the fake waterfalls flow… with imagination.1/2 @MM81792127 @GundamNorthrop @SolomonYue ...
Sampling the surface of a glacier. There is increasingly dense firn between surface snow and blue glacier ice. Firn field on the top of Säuleck, Hohe Tauern. Firn (/ f ɪər n /; from Swiss German firn "last year's", cognate with before) is partially compacted névé, a type of snow that has been left over from past seasons and has been recrystallized into a substance denser than névé.
