Snow density See relative density. GCW Glossary 2023.03.27
Snow density The ratio of the volume of meltwater that can be derived from a sample of snow to the original volume of the sample; strictly speaking, this is the specific gravity of the snow sample. Freshly fallen snow usually has a snow density of 0.07 to 0.15; glacial ice formed from compacted snow (or firn) has a maximum density of about 0.91. Values as low as 0.004 have been measured. GCW Glossary 2023.03.27
Snow density The mass of snow per unit volume which is equal to the water content of the snow divided by its depth. GCW Glossary 2023.03.27
Snow density The mass of snow per unit volume which is equal to the water content of snow divided by its depth. GCW Glossary 2023.03.27
Snow density The mass of snow per unit volume which is equal to the water content of the snow divided by its depth. GCW Glossary 2023.03.27
Snow density Mass of snowpack per unit volume. GCW Glossary 2023.03.27
Snow depth In the firn area, the vertical distance between the glacier surface and the summer surface; outside the firn area, the vertical distance between the glacier surface and the ice surface (which may be s uperimposed ice or glacier ice) at the time of observation. GCW Glossary 2023.03.27
Snow depth The combined total depth of both the old and new snow on the ground. GCW Glossary 2023.03.27
Snow depth The combined total depth of both the old and new snow on the ground. GCW Glossary 2023.03.27
Snow depth Vertical distance between the surface of a snow layer and the ground, assuming the layer is evenly spread over the ground which it covers. (TR) GCW Glossary 2023.03.27
Snow depth Snow depth is the depth of accumulated snow on the ground, measured at several points that appear representative of the immediate area and then averaged. GCW Glossary 2023.03.27
Snow depth The combined total depth of both old and new snow on the ground. GCW Glossary 2023.03.27
Snowdrift Mass of snow heaped up by the wind and deposited along an obstruction or an irregularity of the terrain. GCW Glossary 2023.03.27
Snowdrift Accumulation of snow heaped together by the wind in the lee of an obstruction due to the local decrease in wind velocity. GCW Glossary 2023.03.27
Snowdrift A mound or bank of snow deposited as sloping surfaces and peaks, often behind obstacles, irregularities, and on lee slopes. Due to eddies in the wind field. GCW Glossary 2023.03.27
Snowdrift An accumulation of wind-blown snow, commonly considerably thicker than the surrounding snowcover GCW Glossary 2023.03.27
Snowdrift An accumulation of wind-blown snow deposited in the lee of obstructions or heaped by wind eddies. GCW Glossary 2023.03.27
Snowdrift Sea ice terminology. Describes an accumulation of wind-blown snow that is deposited in the lee of an obstacle. A crescent-shaped snowdrift, with ends pointing down-wind, is called a snow barchan. GCW Glossary 2023.03.27
Snowdrift An accumulation or bank of snow formed when wind blows snow against an obstruction; often considerably thicker than the surrounding snowcover. GCW Glossary 2023.03.27
Snowdrift An accumulation of windblown snow deposited in the lee of obstructions or heaped by wind eddies. A crescent-shaped snowdrift, with ends pointing downwind, is known as a snow barchan. GCW Glossary 2023.03.27
