A report on Snow
Snow comprises individual ice crystals that grow while suspended in the atmosphere—usually within clouds—and then fall, accumulating on the ground where they undergo further changes.

He first became interested in snow crystals as a teenager on his family farm.
Névé
1 linksNévé is a young, granular type of snow which has been partially melted, refrozen and compacted, yet precedes the form of ice.
Blowing snow
1 linksBlowing snow is snow lifted from the surface by the wind, at eye level (1.8 m) or more, that will reduce visibility.
Firn
1 linksFirn (from Swiss German firn "last year's", cognate with before) is partially compacted névé, a type of snow that has been left over from past seasons and has been recrystallized into a substance denser than névé.
Ski wax
1 linksSki wax is a material applied to the bottom of snow runners, including skis, snowboards, and toboggans, to improve their coefficient of friction performance under varying snow conditions.
Snowmobile
0 linksA snowmobile, also known as a Ski-Doo, snowmachine, sled, motor sled, motor sledge, skimobile, or snow scooter, is a motorized vehicle designed for winter travel and recreation on snow.
Sublimation (phase transition)
0 linksTransition of a substance directly from the solid to the gas state, without passing through the liquid state.
Transition of a substance directly from the solid to the gas state, without passing through the liquid state.
Snow and ice sublime, although more slowly, at temperatures below the freezing/melting point temperature line at 0 °C for partial pressures below the triple point pressure of 612 Pa. In freeze-drying, the material to be dehydrated is frozen and its water is allowed to sublime under reduced pressure or vacuum.
Rainband

Banding within the comma head precipitation pattern of an extratropical cyclone can yield significant amounts of rain or snow.
Shower (precipitation)
0 linksMode of precipitation characterized by an abrupt start and end and by rapid variations in intensity.
Mode of precipitation characterized by an abrupt start and end and by rapid variations in intensity.
A shower will produce rain if the temperature is above the freezing point in the cloud, or snow / ice pellets / snow pellets / hail if the temperature is below it at some point.
