Classifications of snow - Wikipedia
Snow on the ground forms a variety of shapes, formed by wind and thermal processes, all subject to formal classifications both by scientists and by ski resorts. Those who work and play in snowy landscapes have informal classifications, as well.
Winter Weather Terms - National Weather Service
Snow (SN, SNW, S): Snow is an aggregate of ice crystals that form into flakes. Snow forms at temperatures below freezing. For snow to reach the earth's surface the entire temperature profile in the troposphere needs to be at or below freezing.
Severe Weather 101: Winter Weather Types - NOAA National …
Sometimes strong winds pick up snow that has already fallen, creating a ground blizzard. An ice storm is a storm which results in the accumulation of at least .25” of ice on exposed surfaces. They create hazardous driving and walking conditions. Tree branches and powerlines can easily snap under the weight of the ice.
Science of Snow - National Snow and Ice Data Center
A cornice is an overhanging accumulation of ice and wind-blown snow, characteristically found on the edge of a ridge or cliff face. A crust is a hard snow surface lying upon a softer layer, formed by sun, rain, or wind.
Snow - Wikipedia
Icings resulting from meltwater at the bottom of the snow pack on the roof, flowing and refreezing at the eave as icicles and from leaking into the wall via an ice dam. Snow loads and icings are two principal issues for roofs. Snow loads are related to the climate in which a structure is sited.
