Snowline The lower boundary of a highland region in which snow never melts GCW Glossary 2023.03.27
Snowline (1) Climatic snowline: lowest altitude of a continuous layer of snow on the high mountains in summer. (2) Orographic snowline: lowest altitude at which snow persists on the land surface as isolated co verings on the mountains in summer. GCW Glossary 2023.03.27
Snow load The downward force on an object or structure caused by the weight of accumulated snow. GCW Glossary 2023.03.27
Snow lying The actual depth of snow lying on the ground at a particular instant. GCW Glossary 2023.03.27
Snow mat A special device used to mark the surface between old and new snow. It consists of a piece of white duck 28 inches square, having in each corner triangular pockets in which are inserted slats placed d iagonally to keep the mat taut and flat. GCW Glossary 2023.03.27
Snow melt (1) Transformation of snow into liquid water. (2) Water from melting snow. GCW Glossary 2023.03.27
Snow melt Conversion of snow into runoff and groundwater flow with the onset of warmer temperatures. GCW Glossary 2023.03.27
Snowmelt Melting of the snowcover, and also the period during which melting of the snow cover occurs at the end of the winter. GCW Glossary 2023.03.27
Snowmelt The water resulting from the melting of snow. GCW Glossary 2023.03.27
Snowmelt (1) Transformation of snow into liquid water. (2) Water from the melting of snow. GCW Glossary 2023.03.27
Snowmelt No definition provided Ryan McGranaghan 2023.04.16
Snowmelt Melting of the Snow Cover, and also the period during which melting of the Snow Cover occurs at the end of the winter. GCW Glossary 2023.03.27
Snowmelt Melting of the snowcover, and also the period during which melting of the snowcover occurs at the end of the winter GCW Glossary 2023.03.27
Snowmelt flood Significant flood rise in a river caused by the melting of snowpack accumulated during the winter. GCW Glossary 2023.03.27
Snowmelt flood In hydrologic terms, flooding caused primarily by the melting of snow. GCW Glossary 2023.03.27
Snowmelt flood Flooding caused primarily by the melting of snow. GCW Glossary 2023.03.27
Snowmelt flood A substantial rise in stream or river discharge caused by snowmelt runoff. GCW Glossary 2023.03.27
Snow metamorphism The transformation that the snow undergoes in the period from deposition to either melting or passage to glacial ice. Meteorological conditions as well as mechanical or gravitational stresses are the primary external factors that affect snow metamorphism. Dry snow metamorphism is governed by both equilibrium and kinetic growth. In presence of liquid water snow transformation is driven by wet snow metamorphism. In English, snow metamorphism is sometimes and incorrectly called snowmetamorphosis. GCW Glossary 2023.03.27
Snow on the ground The depth of snow in centimetres (cm) on the ground. The total depth of snow on the ground at the time of the observation is determined in whole centimetres by making a series of measurements and taki ng the average. GCW Glossary 2023.03.27
