Meaning of Cyclone

What is Cyclone:

A cyclone is the natural phenomenon formed by strong winds that advance in a circular manner on themselves and that are generated in areas with low atmospheric pressure.

Likewise, the term cyclone is also used to refer to atmospheric regions of low pressure or storm, in which abundant rainfall occurs accompanied by strong winds and, in some cases, an anticyclone.

The word cyclone derives from English cyclone, and this in turn comes from the Greek kyklôn, which means "swirl." As synonyms for cyclone, the terms hurricane and storm can be used.

Cyclones originate in areas whose atmospheric pressure is lower than the one around them, generally on tropical coasts and, thanks to scientific and technological advances, they can be seen and followed from the moment they form until they dissipate. .

Therefore, cyclones can be predicted, which makes it possible to alert 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 intense winds that rotate in circles on itself. This meteorological phenomenon is usually accompanied by torrential rains, sometimes with electrical discharges and, at sea, waves and strong tides.

Cyclone types

There are different types of cyclone which can be classified from the strength of the wind, which is usually around more than 100 kilometers per hour.

Tropical cyclone

The tropical cyclone, tropical storm, hurricane or typhoon, usually forms in the oceans whose warm waters generates an unstable atmosphere and gives rise to the low-pressure system, from which the cyclone takes energy from the processes of evaporation and condensation of the air damp.

It is characterized by having a swirl shape with a low pressure center or eye. Likewise, 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 path.

For this reason they are classified into five categories according to wind speed. In the northern hemisphere the cyclone rotates counterclockwise and in the southern hemisphere it rotates counterclockwise.

Extratropical cyclone

The extratropical cyclone forms in the middle latitudes between 30 ° and 60 ° from the equator. This cyclone is composed of two or more air masses, so it is 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.

Subtropical cyclone

This cyclone is generally formed in latitudes near the equator, in addition, it has characteristics of both a tropical cyclone and an extratropical cyclone.

Polar 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 a vortex of air 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, resulting in storms and abundant rains.

On the contrary, the anticyclone is a region whose atmospheric pressure is greater than that which surrounds it, hence it generates good weather and clear skies.

However, both cyclones and anticyclones are important for generating atmospheric winds and currents.
