In years when the snow cover is low, more radiation is absorbed, and that extra energy drives more evaporation. Conversely, an extensive cover of snow suppresses evaporation. bing wallpapers app for pcWebSnow and cloud surfaces have a high albedo, because most of the energy of the visible solar spectrum is reflected. Vegetation and ocean surfaces have low albedo, because they absorb a large fraction of the energy. Clouds are the chief cause of variations in the Earth's albedo.
