"WebIf the albedo of a surface is high, more radiation will be reflected than if the albedo is low. Hence, the average albedo of the planet dictates the levels of solar radiation held and reflected at its surface. Fresh snow has a particularly high albedo. This reflective property results in amplification of the solar forcing of air temperature. " - High albedo snow

Albedo is an expression of the ability of surfaces to reflect sunlight (heat from the sun). Light-coloured surfaces return a large part of the sunrays back to the atmosphere (high albedo). Dark surfaces absorb the rays from the sun (low albedo). Ice- and snow-covered areas have high albedo, and an ice-covered Arctic ...

Web29 de mar. de 2024 · Snow cover, because of its high albedo, is a shield that reduces the amount of solar radiation absorbed by the basin. 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.
