Understanding Blizzards

The video discusses the history and impact of major blizzards, defining them as severe snowstorms with strong winds and low visibility. It explains the conditions necessary for blizzard formation, including moisture, air mass interaction, and freezing temperatures. The role of the jet stream in blizzard formation is highlighted, along with the dangers and economic consequences of blizzards, such as frostbite, hypothermia, travel hazards, and infrastructure damage.
