What is blizzard? The blizzard and blizzard are one and the same?

How many people know about what a blizzard is? It would seem that this is another synonym for the word blizzard, but it is worth pondering, and it becomes clear - the difference between them is huge. Especially if we consider these atmospheric phenomena through the eyes of a meteorologist. So let's throw aside prejudice and find out what a blizzard really is.

The blizzard and blizzard are one and the same?

So, a blizzard is an atmospheric phenomenon, during which the wind raises an abundant amount of snow. Because of this, it seems that everything around was covered with a white veil of small and large snowflakes. If so, what does the blizzard mean?

In general, this is the same. But unlike the blizzard, the blizzard lifts only the snow lying on the ground. That is, this atmospheric phenomenon can not occur during snowfalls or after the snow has become covered with ice crust.

In this there is a fundamental difference between these two meteorological concepts. What is true, from a scientific point of view, purga is considered to be one of the types of blizzard blizzard.

What is a blizzard in really?

Most often, a snowstorm occurs on plains such as a field or steppe. This occurs under the influence of a low-lying wind, whose speed exceeds 7 m / s. This force allows him to easily lift the upper layers of snow into the air, unless they have hardened from numerous temperature changes.

The main feature of the blizzard is that it is able to raise the white veil even on the brightest and sunny days. At the same time, the snow chased by the wind lies back not in an even layer, but with humpbacks and rushes. Looking at this it seems that the snow behaves like sand in the desert, forming sand dunes and endless dunes.

Unpredictable snow creator - that's what a blizzard is. It can start from a small gust of wind, and just as suddenly disappear. Leaving behind him only a memory and an unusual pattern on a snow-white canvas made of snow.
