What is it?
A severe snowstorm with high winds and lots of snow.
How does it form?
You need three things for a blizzard to form: cold air is that is at the surface, lots of moisture, and winds. Warm air must rise over cold air to form intense snowfall. There are two ways that this may happen. Winds pull the cold air toward the equator from the poles and bring warm air toward the poles from the equator. When warm air and cold air are brought together, a front is formed and snow occurs.
How humans have prepared
Changes that humans have made to protect themselves against blizzards is wearing the appropriate apparel ( snow pants, winter coat, gloves, hats) , having indoor heating, snowplows, shovels to have better transportation.
The New York streets were buried with snow during the 1888 blizzard. People in Maryland and Virginia to Maine were trapped in the blizzard. More than 3 ft of snow fell and the communication was cut off too. Tons of stores and property were destroyed in the storm. And 500 people died.
A smaller blizzard was the first blizzard of 2015 in the eastern United States it continued to slam Long Island and New England, bringing many communities to a standstill. No one died.
