Snow cover 1) In general, a layer of snow on the ground surface. 2) The areal extent of snow-covered ground, usually expressed as per cent of total area in a given region.
Effects of Snow Cover on forecasted temperatures
As the sun's rays hit the surface of the earth, much of it is absorbed by the surface (as in the diagram below). This in turn warms the air near the earth's surface, causing the temperature to rise.
snow cover - 1. The areal extent of snow-covered ground, usually expressed as percent of total area in a given region. 2. In general, a layer of snow on the ground surface. Compare snowfield, snowpack. 3.
SNOW COVER The areal extent of ground covered by the snow. It is usually expressed as a percent of the total area of a given region.
SNOW CREEP A continuous, extremely slow, downhill movement of a layer of snow.
In Australia, it is described as a violent and very cold wind which is loaded with snow, some of which has been raised from snow covered ground.
Snow Accumulation and Ablation ModelIn hydrologic terms, a model which simulates snow pack accumulation, heat exchange at the air-snow interface, areal extent of snow cover, heat storage within the snow pack, liquid water retention, ...
accumulation (glacial) All processes, which include snowfall, condensation, avalanching, snow transport by wind, and freezing of liquid water, that add snow or ice to a glacier, floating ice, or snow cover.
Snow Core Sample: A core sample of the snow cover to measure how much liquid precipitaion is within the core. Solar Angle: High:"High Solar Angle" when the Sun is directly overhead.
Also, the more reports of snow lying are made the better as the 'synoptic/climatological' network doesn't always pick up the variability of nation-wide snow cover.
As snow cover ripens and decays in cold temperatures, the suns rays begin to melt the snow where its density is lowest. Hollows form and deepen in the snow crust.
These were also years of heavy snow cover on the Victorian Alps. In each case weather patterns were characterised by strong, persistent westerlies and abundant rain at lower levels.
A NOHRSC program that uses satellite data to generate areal extent of snow cover data over large areas of the western United States.

Tilted toward the sun, an adret is characterized by higher temperatures, a longer growing season, less snow cover and a shorter duration of snow cover, and a higher timber line and snow line than the shaded side (the ubac).
Ice Caps: A perennial ice/snow cover over an extensive area of land or sea, today found only around the two geographic poles.
Albedo- The percentage of light reflected by an object. Snow covered areas have a high albedo (0.9 or 90%) due to their white color.
Satellite Hydrology Program: A NOHRSC program that uses satellite data to generate areal extent of snow cover data over large areas of the western United States.
Water mass in the snow cover attenuates the terrestrial radiation signal.
These meteorological satellites, however, see more than clouds and cloud systems. City lights, fires, pollution, auroras, sand and dust storms, snow cover, ice mapping, ocean currents, energy waste, etc.
the albedo of wet sand is 9, meaning that about 9% of the incident insolation is reflected; albedoes of other surfaces range upward to 80-85 for fresh snow cover; ...
Snow survey Determination of the total amount of snow covering a watershed or a given region.
