Snow grains - Wikipedia

Snow events reflect the type of storm that generates them and the type of precipitation that results. Classification systems use rates of deposition, types of precipitation, visibility, duration and wind speed to characterize such events. The following terms are consistent with the classifications of United States National Weather Service and the Meteorological Service of Canada: WebApr 15, 2024 · The Arctic snow outside of Greenland has typically 20 ppb of BC, which is sufficient to reduce snow albedo by approximately 1%, depending on snow grain size. This small change in albedo is difficult to detect by radiation measurements at the surface, and even more difficult to detect by remote sensing [ 27 ], but it is important for climate. WebIn dry conditions, snow grains can change size and shape under a temperature gradient where grain growth is observed owing to the mass transfer from warmer to colder grains, typically forming faceted and depth hoar grains ( Colbeck, 1983; Gubler, 1985 ). clangers space
