Snow lifted from the surface of the earth by the wind and lifted to a height of six feet or more above the surface and blown in a way the horizontal visibility is reduced. Blowing snow is a classic requirement for blizzard conditions.
wind blown snow that reduces horizontal visibility.
Wind driven snow that reduces visibility to six miles or less causing significant drifting. Blowing snow may be snow that is falling and/or loose snow on the ground picked up by the wind.
wind-driven snow that reduces visibility near the ground. Blowing snow can be falling snow or snow that has already accumulated but is picked up and blown by strong winds.
Wind-driven sand that significantly reduces surface visibility to less than 7 miles.
Wind-driven snow that significantly reduces surface visibility to less than seven miles.
Snow lifted from the earth's surface by the wind to a height of 2 meters or more. Blowing snow is higher than drifting snow.
Snow that is raised by the wind to heights of six feet or greater. It is reported as "BLSN" in an observation and on the METAR.
