What is Cyclone?
The natural phenomenon formed by strong winds that advance in a circular way on themselves and that are generated in areas whose atmospheric pressure is low is called a cyclone.
Likewise, the term cyclone is also used to refer to atmospheric regions of low pressure or storms , in which abundant rainfall occurs accompanied by strong winds and, in some cases, an anticyclone.
The word cyclone derives from the English cyclone , and this in turn comes from the Greek kyklôn, which means “to swirl”. The terms hurricane and storm can be used as synonyms for cyclone.
Cyclones originate in those areas where the atmospheric pressure is lower than the one around them, generally on the tropical coasts and, thanks to scientific and technological advances, they can be seen and followed from their formation until it dissipates. .
Therefore, cyclones can be predicted, which allows alerting the population that will be affected to take the necessary protection and prevention measures, since after the passage of a cyclone there are usually material losses, damage and floods that affect many people.
In general, the cyclone is characterized by forming an abnormal concentration of clouds accompanied by strong winds that spin in circles on itself. This meteorological phenomenon is usually accompanied by torrential rains, sometimes with electric shocks and, in the sea, waves and strong tides.
There are different types of cyclone which can be classified from the force of the wind that is usually around more than 100 kilometers per hour.
The tropical cyclone, tropical storm, hurricane or typhoon, generally forms in the oceans whose hot waters generate an unstable atmosphere and give rise to the low-pressure system, from which the cyclone draws energy from the evaporation and condensation processes of the air damp.
It is characterized by having a swirl shape with a center or low pressure eye. Also, it generates strong winds and rains that are dangerous because they can reach an approximate speed between 120 km / h or 300 km / h, so the cyclone usually destroys what it gets in its way.
For this reason they are classified into five categories according to wind speed. In the northern hemisphere the cyclone rotates counter-clockwise and in the southern hemisphere it rotates backwards.
The extratropical cyclone forms in the mid latitudes between 30 ° and 60 ° from the equator. This cyclone is made up of two or more air masses, making it a phenomenon that is related to one or more fronts.
The extratropical cyclone is associated with the low pressure system that exists between the tropics and the poles. Specialists have determined that extratropical cyclones are unique and unrepeatable since they can vary due to the contrast of hot or cold air masses.
This cyclone generally forms in latitudes close to the equator, and it also has characteristics of both the tropical cyclone and the extratropical cyclone.
This cyclone is characterized by having a diameter of approximately or greater than 1000 km. It has a shorter life than the tropical cyclone, it develops faster and the wind force is established in 24 hours.
A mesocyclone is an air vortex that measures between 2 and 10 km in diameter and forms within convective storms, that is, a rotating storm that can even form a tornado.
Cyclone and anticyclone
As already mentioned, the cyclone is a series of strong winds that form in areas of low atmospheric pressure, causing storms and abundant rainfall.
On the contrary, the anticyclone is a region whose atmospheric pressure is greater than that which surrounds it, which is why they generate good weather and clear skies.
However, both cyclones and anticyclones are important in generating winds and atmospheric currents.
