Definition: An ensemble of snow particles raised by the wind to a small height above the ground. The visibility is not sensibly diminished at eye level.  WMOMeteoterm 

Snow raised from the surface of the earth by the wind to a height of less than 1.5 to 2.0 meters (5 to 6.6 feet) above the surface; it dose not restrict horizontal visibility at 2 meters (6.6 feet) or more above the surface.  NSIDCCryosphere 

Drifting snow is an uneven distribution of snowfall/snow depth caused by strong surface winds. Drifting snow may occur during or after a snowfall. Drifting snow is usually associated with blowing snow.  NOAA-NWS 

Snow entrained and transported within 2 m of the surface by the wind. The height of 2 m is a convenient separator between drifting snow, which does not reduce sensibly the horizontal visibility at eye level, and blowing snow. See windborne snow.  IHPGlacierMassBalance 

Snow that is raised from the earth's surface by the wind to a height of less than 2 metres.  ECCCanada 

Snow raised from the surface of the earth by the wind to a height of less than 6 ft above the surface. In aviation weather observations, drifting snow is not regarded as an obstruction to vision because it does not restrict horizontal visibility at 6 ft or more above the surface. When snow is raised 6 ft or more above the surface, it is classified as blowing snow.  AMSglossary 

An ensemble of snow particles raised by the wind to small heights above the ground. The visibility is not sensibly diminished at eye level (cf. Blowing snow).  SPRI
