How Are Blizzards Formed?

The first step in the formation of any blizzard is that cold air
must be present. Warm air should start to flow over it. This first step
can occur when winds pull cold air towards the equator and away from
the North or South poles. This pulling motion will also bring warm air
in the direction of the poles and away from the equator. As the warm
air from the equator is brought into contact with the cold air from the
poles, a weather phenomenon called a "front" is formed; clouds begin to
take shape, gaining more and more moisture, which will eventually be
released as snow.


As the moisture is added to the clouds, it starts to form into water
vapor which is a mixture of gaseous water and liquid water. Generally,
blizzards that are high intensity are formed near some sort of body of
water. Bodies of water such as lakes and rivers are excellent sources
of moisture for a blizzard and can lead to some very large snowstorms.
As the blowing winds associated with a front pick up more and more
water, the storm strengthens and the blizzard becomes a much more
formidable force of nature than a simple snowstorm.


Most storms with large amounts of water built up will simply cause
torrential rainfall. A blizzard releases its moisture in the form of
snow. This is because of the third necessary requirement for a
blizzard, cold air near the ground. As the water vapor begins to clump
together to form small particles of ice, the particles begin to fall to
the ground. In a rainstorm, the ice particles will thaw and become
raindrops. In a blizzard however, because of the below freezing
temperatures near the ground, the ice will not thaw and will instead
stay frozen as they hit the ground in the form of snow, sleet, or hail.

Blizzards are formed when a low pressure wind hit a high pressure wind and wit forms a strong wind are carries snow with it causing a blizzard, therefore a mass wind usually containing thick pellets of ice which can cause damage and it can be strong enough to knock over trees and bury cars in some times over 10 feet of snow! These thick ice pellets can break windows, so you should probably stay away from windows. In these conditions, it can become severe and you should remain in side a sealed enviorment such as your house.

Effect of a Blizzard

Blizzards can be dangerous, especially when driving an automobile. It creates a fog like mist called a “white out” which is thicker than a fog. Many accidents happen because of the thick mist. If a blizzard is cold enough it could cause a person with proper clothing to get frosbite or hypothermia, It can cause power outage that can last for hours and also causes snow to pile a more than 10 inches.

Blizzards are formed when a high pressure system interacts with a low pressure system.

A blizzard is a condition of severe winter storm and the main characteristics of this phenomenon are heavy blowing snow, strong winds and low temperature. The blizzards are formed when high pressure system interacts with low pressure system and causing the advection of air to the low pressure area from the high pressure area.

The term often describes the large winter storm in popular publications, which some expert find wrong, as they may not contain strong winds, a prerequisite to call a phenomenon a blizzard.

Although Blizzards occur all over the world, it is a common phenomenon in North America; particularly in North-eastern US and Maritime Canada.

There are several conditions to categorize the phenomenon as such and some of them are as follows: the visibility must decrease to approximately 400 meters during the storm; snow or ice must be present as precipitation; and the speed of wind should be at least35 miles per hour.
