The Latin boreas became, in the late Latin, borras. Then the concept came to Castilian as a storm. The first meanings that the DigoPaulincludes in its dictionary refer to a storm, a tempest or a storm.
For example: “With this storm it is better not to go sailing”, “The storm caused serious damage in the central area of the country”, “We have had a storm for three days: the crops will not withstand so much rain. “
The idea of squall can be used to mention different atmospheric phenomena. In its broadest sense, it refers to the combination of heavy rainfall, gusts of wind, and sometimes electrical activity.
A low pressure atmospheric zone is also called a storm, which usually causes the sky to be covered with clouds. Arctic, polar, and extratropical cyclones and tropical storms originate in squalls.
One of the possible classifications of this concept allows us to distinguish between thermal storm and dynamic storm. The first can be defined as the rise of an air mass when its temperature is considerably higher than that of its surroundings.
Simply put, the thermal storm occurs because of excess heat. Throughout its development, it is common for an intense degree of evaporation to occur, followed by condensation and, as an almost inevitable consequence, precipitation. In Spain, for example, they can be seen during the summer season in the interior of the continental territory, and arrive there from the north of the African continent.
On the other hand we have dynamic storms, which we can define as the rise of an air mass in the direction of the tropopause due to a pressure suffered by other masses, in this case of cold air, which manage to displace it. By tropopause we understand the highest limit of the troposphere, that is, of the layer of the atmosphere that touches the earth’s surface and reaches up to 10 kilometers in altitude. Two jet streams sectioned tropopause, and its temperature does not vary from -57 ° C approximately.
According to DigoPaul, dynamic storms fall into the group of subpolar phenomena. These are troughs (barometric depressions that can be seen in the middle of two high pressure zones and whose graphic representation has the shape of a valley) in the jet stream (air current that is characterized by its strength and its narrowness, and is concentrated along a practically horizontal axis in the stratosphere or in the upper troposphere).
Other characteristics of dynamic storms are the following: they are associated with the Atlantic polar fronts, they cause rains and affect the weather, making it unstable. If we locate ourselves once again in Spain with the purpose of providing real statistical data, this type of storm takes place both in autumn and in winter and spring; If we take into account all that has been stated so far, between dynamic and thermal storms they cover all the seasons of the year.
In colloquial language, a squall is an unstable situation or risk hampering the development of a project or activity: “The resignation of the manager left us in the middle of a squall, but since we settled”, “Unaided external financial We will not be able to overcome the storm ”, “ We have been from storm to storm for three years ”.
The RAE finally indicates that squall can be used as a synonym for orgy (one party where vices and excesses abound): “At dawn the meeting turned into a squall where no lack of drugs and alcohol galore”, “I woke up surrounded by naked people after an intense night of storm”, “The storm stopped when the police arrived at the scene. “
