karaburan

OBS: [Le buran est un] vent fort du nord-est en Russie et en Asie centrale. Lorsque le vent soulève la neige du sol, on l'appelle buran blanc; dans la toundra, on le nomme purga. En été, le buran soulève des nuages de poussières et est appelé pour cette raison karaburan ou buran noir.

OBS: It carries clouds of dust (which darken the sky) instead of snow.
OBS: [A buran is] a strong northeast wind in Russia and central Asia. It is most frequent in winter when it resembles a blizzard, that is, very cold and lifting snow from the ground; as such it is called white buran or, on the tundra, purga. A similar wind in Alaska is called burga. The buran also occurs, but less frequently, in summer, when it raises dust clouds; it is then called karaburan.
