暴风雪介绍（维基）：A blizzard is a severe snowstorm characterized by strong winds and low temperatures. The difference between a blizzard and a snowstorm is the strength of the wind. To be a blizzard, a snow storm must have sustained winds or frequent gusts that are greater than or equal to 56 km/h (35 mph) with blowing or drifting snow which reducesvisibility to 400 meters or a quarter mile or less and must last for a prolonged period of time — typically three hours or more.[1] Snowfall amounts do not have to be significant. In Australia the definition requires that at least some snow has been raised from the ground.[2]
A severe blizzard has winds over 72 km/h (45 mph), near zero visibility, and temperatures of −12 °C (10 °F) or lower. A ground blizzard has snowdrifts and blowing snow near the ground, but no falling snow.[3]
Blizzards can bring near-whiteout conditions, and can paralyze regions for days at a time, particularly where snowfall is unusual or rare. The 1972 Iran blizzard, which caused approximately 4,000 deaths, was the deadliest in recorded history.
