blizzard,winter storm characterized by high winds, low temperatures, and driving snow; according to the official definition given in 1958 by the U.S. Weather Bureau, the winds must exceed 35 mi (56 km) per hr and the temperature 20°F; (−7°C;) or lower.

a term used in the USA to denote the Russian metel’ (mainly with swirling snow along the ground) having strong northwest winds and temperatures far below zero. Blizzards occur in winter in the trailing edges of cyclones. In a broader meaning (in the USA and Great Britain) this term is applied to any metel’ with strong winds and is analogous to the Russian concepts of purga and buran. “Blizzard” is also used to describe strong outflowing winds on Adélie Land in Antarctica.
