A blizzard is a severe snowstorm characterized by strong winds, low temperatures, and reduced visibility due to blowing snow. These conditions can make travel and outdoor activities extremely dangerous.
Formation of Blizzards
Blizzards typically form when a mass of cold, dense air collides with a warm, moist air mass. As the warm air rises and cools, it condenses into clouds and precipitation. When the temperature is near or below freezing, the precipitation falls as snow. Strong winds then pick up the snow and create whiteout conditions, reducing visibility to near zero.
Characteristics of Blizzards
Snowfall: Blizzards are accompanied by heavy snowfall, leading to significant accumulation.
Wind: Blizzards have sustained winds of at least 35 miles per hour, creating blinding snowdrifts.
Understanding blizzards is important for being prepared and staying safe during these extreme weather events. Stay informed and take necessary precautions to minimize the risks associated with blizzards.
Use models (e.g., diagrams, maps, globes, digital representations) to explain how the rotation of Earth and unequal heating of its surface create patterns of atmospheric and oceanic circulation that determine regional climates.
