Who / What
A blizzard is a severe snowstorm characterized by strong sustained winds and low visibility, lasting typically at least three to four hours. It often involves wind moving existing snow, creating a ground blizzard, and can span hundreds or thousands of kilometres.
Background & History
Blizzards, as a meteorological phenomenon, have been recognized for centuries, with modern terminology emerging in the early 20th century as weather science advanced. The term “blizzard” was first documented in the 1930s and became standard in meteorological discourse thereafter.
Why Notable
Blizzards are significant due to their potential for widespread disruption, posing hazards to transportation, aviation, and infrastructure. Their extreme wind and visibility conditions can cause extensive economic losses, power outages, and even fatalities, making them a focus for weather warnings and disaster preparedness.
In the News
Recent storms across North America and Europe have produced blizzard conditions, prompting emergency alerts and travel restrictions. Climate‑change researchers warn that blizzards may be increasing in intensity and frequency, underscoring the urgency of adaptation and mitigation measures.
