People who personally feel what a storm is, say that it is fascinating. The power of the totality of the manifestations of nature makes you feel awe. However, the answer to the question of what a storm is is simple - it's the wind. In everyday life, it is customary to use this concept as a designation of a pretty bad weather on the water, accompanied by large waves and wind, but this is not entirely accurate. The ambiguity in semantic definitions has now appeared, probably due to a confusion in the use of such close concepts as a storm and a storm, which are, in fact, one and the same.
The quality of a storm (or storm) is given by that place on the earth's surface where bad weather6 occurs in snow - a snow storm, in sand - a sand storm, on water - a water storm. What is a storm? In fact, it is a fast wind. This concept is between two "neighbors": a very strong wind on one side (when trees break) and a hurricane that destroys even buildings on the other.
Storm detection
If you determine exactly what a storm is, it turns out that it is a wind whose speed is in the range of about 20 to 30 m / s. How to understand how much this wind speed is? To feel it personally, it is enough to look out through an open car window at a speed of more than 70 km / h - the exact same air flow, and in gusts and much more, will meet a person who has landed in this bad weather.
Various metrics have been developed to measure storm intensity. The most common in use is the Beaufort scale, which today is used as a universal means of determining wind speed and its effect on land or water.
A storm (or storm) in accordance with the mentioned scale can have three degrees of intensity, measured in points. So, if the Beaufort scale is 12 points, then the share of storms is from 9 to 11 points (12 points is already a hurricane). 9 points - a storm, 10 - a strong storm, 11 - a severe storm that causes significant damage to buildings and structures, and, fortunately, is extremely rare.
Special storms
People who live in favorable climatic zones, sometimes for their whole life, fail to get to know any real storm, unlike mariners (this is a profession that by its very existence involves a person getting into a storm sooner or later). In the society of such people, concepts appear that carry a semantic load only for those who are "in the subject." For example, the 9th shaft is a well-known concept, but not everyone knows that when there is a storm on the water, approximately every 9th wave is much stronger than others and carries a greater danger than others.
The perfect storm is another phenomenon noticed by sailors. To date, this concept has already spread from the professional field to the sphere of everyday language and means an unusual combination of unfavorable circumstances, in which their total influence increases significantly.
So the huge and destructive storm in the United States in 1991 was called ideal because it arose due to an unusual combination of circumstances such as a stream of warm air from a zone of low atmospheric pressure, a counter flow of cold air from a zone of high atmospheric pressure and moisture from a recent hurricane. A good storm is not the rarest natural occurrence.
