Winds pull cold air toward the equator from the poles and bring warmer, moist air toward the poles from the equator. When warm air and cold air are brought together, a front is formed and snow can form. Warm air can also rise to form clouds and blizzard snows as it flows up a mountainside.
What causes snow blizzards?
Most snowstorms form due to low-pressure systems that lift moist air into the atmosphere, but lake effect storms form due to the abundance of moisture from the Great Lakes.
Why are blizzards so cold?
A blizzard forms when heavy snow falls and strong winds blow the snow around, making it hard to see. Blizzards are extremely dangerous because people can lose their way in the blinding snow. The strong wind can create a cold wind chill, making the temperature feel even colder.
How do blizzards work?
In general, blizzards occur when a mass of warmer air collides with a mass of very cold air. The cold air mass cuts under the warm air mass, and as the warm moist air rises upwards it forms snow. The collision of the air masses also provides the atmospheric tension required for high wind speeds.What damage do blizzards cause?

What is A Blizzard? blowing snow in the air that will frequently reduce visibility to 1/4 mile or less for a duration of at least 3 hours. A severe blizzard is considered to have temperatures near or below 10°F, winds exceeding 45 mph, and visibility reduced by snow to near zero.What causes the strong winds?
A pressure gradient is how fast atmospheric pressure changes over distance. So, when pressure changes rapidly over a small distance, the pressure gradient force is large. Strong winds almost always result from large pressure gradients.
How long does a blizzard last?A blizzard is a severe snowstorm characterized by strong sustained winds of at least 56 km/h (35 mph) and lasting for a prolonged period of time—typically three hours or more. A ground blizzard is a weather condition where snow is not falling but loose snow on the ground is lifted and blown by strong winds.
Article first time published onWhat temperature is needed for a blizzard?
Blizzards commonly occur with temperatures around or below 20 degrees Fahrenheit, says weather.com. These low temperatures combined with strong winds create a low wind-chill factor, which is the amount of cooling someone feels from the combination of temperature and wind speed.
Can a blizzard knock down a house?
This can cause water to leak into brickwork, siding and ceiling joists. In serious cases, heavy snow can weigh more than your roof can structurally hold and cause it to collapse. It’s also not uncommon for melting winter snow to flood basements and overload gutters and downspouts.
