What causes blizzards?

Answer 1

Blizzards cause cars to be burying and people could lose their life power lines are often taken.Roofs could fall down.

Answer 2

Causes

Blizzards occur for different reasons which even vary by location. But most frequently, a blizzard (which by definition features strong winds and often heavy snow) requires strengthening low pressure system with large sources of energy and moisture. The moisture often comes from a large body of water, usually an ocean or gulf, while the energy for these systems is provided both by large temperature differences (as found at the boundaries of air masses) as well as vertical motion which tends to be present at times when the jet stream is located overhead. The stronger a storm gets (i.e., the lower the pressure at the center) the greater the pressure gradient becomes and the stronger the wind blows. Lower pressure also facilitates stronger vertical motion, which causes stronger precipitation in the form of snow to accompany the wind.

Effects

The effect of a blizzard is that there can be heavy snow on the ground for weeks after the blizzard has occured and rapid snow melting can cause ice on frozen streams to break into chunks and form ice. Ice jams can cause flooding. Additionally, heavy snowfall and blowing snow can shut down cities and highways by creating hazardous travel conditions. The snow is also costly to remove after it falls.

Answer 3

A blizzard is a severe weather condition characterized by low temperatures and strong winds (greater than 35 mph) bearing a great amount of snow, either falling or blowing.

Blizzards generally occur when cold polar air comes down and mixes with warm and moist air from lower latitudes. It requires a few more complex elements in the atmosphere to get a storm system going, but once it does it can feed on these temperature differences to become stronger. The stronger a storm gets, the "deeper" the low pressure at the center (lower, in other words), which helps to enhance the winds, creating a blizzard.

It occurs when a cold air mass moves out of the Arctic into the temperate zone. The heavy cold sinks along the boundary between the two air masses. This boundary is called a cold front.
A heavy snowstorm is turned into a blizzard by a very strong wind.

Answer 4

Blizzards are caused by a combination of cold air and moisture from the atmosphere mixing to create strong winds and heavy snowfall. They typically occur when a strong low-pressure system meets cold air from the north, resulting in intense snowstorms and reduced visibility. Geography plays a role in the formation of blizzards, with certain regions more susceptible to these severe winter storms.
