microstructure, grain shape, grain size (mm), snow density (kg/m), snow hardness, liquid water content, snow temperature (°C), impurities (mass fraction), and layer thickness (cm). The grain shape is further characterized, using the following categories (with code): precipitation particles (PP), machine-made snow (MM), decomposing and fragmented precipitation particles (DF), rounded grains (RG), faceted crystals (FC), depth hoar (DH), surface hoar (SH), melt forms (MF), and ice formations (IF). Other measurements and characteristics are used as well, including a snow profile of a vertical section of the snowpack. Some snowpack features include:
560: 429: 62: 582: 286: 643:– A variety of processes can create a crust, a layer of snow on the surface of the snowpack that is stronger than the snow below, which may be powder snow. Crusts often result from partial melting of the snow surface by direct sunlight or warm air followed by re-freezing, but can also be created by wind or by surface water. Snow travelers consider the thickness and resulting strength of a crust to determine whether it is "unbreakable", meaning that they will support the weight of the traveler or "breakable", meaning that it will not. 648: 294: 549: 538: 615: 593: 40: 51: 571: 925:– Freshly fallen, uncompacted snow. The density and moisture content of powder snow can vary widely; snowfall in coastal regions and areas with higher humidity is usually heavier than a similar depth of snowfall in an arid or continental region. Light, dry (low moisture content, typically 4–7% water content) powder snow is prized by skiers and snowboarders. It is often found in the 341:, that result in irregular spherical particles, which typically bounce upon impact. Sleet comprises grains of ice that form from refreezing of largely melted snowflakes when falling through into a frozen layer of air near the surface. Small hail forms from snow pellets encased in a thin layer of ice caused either by accretion of droplets or by refreezing of each particle's surface. 960:– Crud covers varieties of snow that all but advanced skiers find impassable. Subtypes are (a) windblown powder with irregularly shaped crust patches and ridges, (b) heavy tracked spring snow re-frozen to leave a deeply rutted surface strewn with loose blocks, (c) a deep layer of heavy snow saturated by rain (although this may go by another term). 258:– Occurs when a snowstorm generates lightning and thunder. It may occur in areas that are prone to a combination of wind and moisture triggers that promote instability, often downwind of lakes or in mountainous terrain. It may occur with intensifying extratropical cyclones. Such events are often associated with intense snowfall. 1027:
Not surprisingly, in languages and cultures where snow is common, having different words for distinct weather conditions and types of snowfall is desirable for efficient communication. Finnish, Icelandic, Norwegian, Russian, and Swedish have multiple words and phrases relating to snow and snowfall,

on a snow surface that is colder than the air. Crystals grow rapidly by transfer of moisture from the atmosphere onto the snow surface, which is cooled below ambient temperature by radiational cooling. Subsequent snowfall can bury layers of surface hoar, incorporating them into the snowpack where

In addition to having material properties, snowpacks have structure which can be characterized. These properties are primarily determined through the actions of wind, sun, and temperature. Such structures have been described by mountaineers and others encountering frozen landscapes, as follows:

describes snow crystal classification, once it is deposited on the ground, that include grain shape and grain size. The system also characterizes the snowpack, as the individual crystals metamorphize and coalesce. It uses the following characteristics (with units) to describe deposited snow:
371:) – Flattened and elongated agglomerations of crystals, typically less than 1 mm diameter, that include a range of crystal sizes and complexities to include a rime core and glaze coating. They typically originate in stratus clouds or from fog and fall in small quantities, not in showers. 533:
Classification of snow on the ground comes from two sources: the science community and the community of those who encounter it in their daily lives. Snow on the ground exists both as a material with varying properties and as a variety of structures, shaped by wind, sun, temperature, and

A 2010 study follows the sometimes questionable scholarship regarding the question whether these languages have many more 391:) – Spherical or conical ice particles, based on a snowlike structure, with diameters between 2 mm and 5 mm. They form by accretion of supercooled droplets near or slightly below the freezing point and rebound off hard surfaces upon landing. 763:– A layer of relatively stiff, hard snow formed by deposition of wind blown snow on the leeward side of a ridge or other sheltered area. Wind slabs can form over weaker, softer freshly fallen powder snow, creating an avalanche hazard on steep slopes. 176:– Characterized by sustained wind or frequent gusts of 56 kilometres per hour (35 mph) or greater and falling or blowing snow that frequently lowers visibility to less than 400 metres (0.25 mi) over a period of 3 hours or longer. 139:
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.
276:– May constitute any combination of sleet, snow, ice, and wind that accumulates 18 centimetres (7 in) or more of snow in 12 hours or less; or 23 centimetres (9 in) or more in 24 hours or 1.3 centimetres (0.5 in) of ice. 757:– A layer of relatively stiff, hard snow formed by deposition of wind blown snow on the windward side of a ridge or other sheltered area. Wind crusts generally bond better to snowpack layers below and above them than wind slabs. 824:

Snowfall arises from a variety of events that vary in intensity and cause, subject to classification by weather bureaus. Some snowstorms are part of a larger weather pattern. Other snowfall occurs from
79:-generating weather events, including the individual crystals both in the air and on the ground, and the deposited snow pack as it changes over time. Snow can be classified by describing the 91:, how it collects on the ground, and thereafter how it changes form and composition. Depending on the status of the snow in the air or on the ground, a different classification applies. 1639:
