A blizzard is a severe snowstorm characterized by strong winds, low temperatures, and reduced visibility due to blowing snow. These conditions can create hazardous travel conditions and may lead to road closures and transportation delays. Blizzard conditions often occur in regions with cold climates, such as the northern United States and Canada, and can last for several hours or even days.Why and How it Happens
Blizzards occur when cold air masses from the Arctic collide with warmer air masses, typically over land. As the warm air rises and cools, it forms clouds that release snowfall. Strong winds then whip up the fallen snow, reducing visibility and creating the characteristic blizzard conditions. These conditions are often exacerbated by factors such as low pressure systems and topographical features like mountains, which can intensify snowfall and wind speeds.
