Hurricane


A hurricane is a very strong wind that originates over tropical seas, which turns in the form of a whirlpool, carrying moisture in enormous quantities and when it touches populated areas, it generally causes destructive damage.

The term Hurricane comes from the name given by the Mayan Indians to the god of storms and diabolical spirits. It is also called the tropical cycle, even in other regions it has another name: typhoon (west Pacific), baguio (Philippines), willy-willies (Australia), cyclone (far east), tanio (Haiti) or cordonazo (North America or Central).

Hurricanes present very fast wind systems that are caused in tropical areas, when the temperature of the sea surface is equal to or greater than 27 ºC, and intensify in circular movements around a center of low pressure known as the eye of the hurricane. , usually 30 to 50 km in diameter. Cloud bands with circulating air rotate counterclockwise in the Northern Hemisphere, and counterclockwise in the Southern.

There are several regions where the presence of hurricanes is born, such as the Caribbean Sea, the Gulf of Mexico, the Western Atlantic Ocean, northern Australia, the Bay of Bengal, southern Indonesia, the Western Pacific Ocean, the Sea of ​​Japan, the Arabian Sea, among others. . The only tropical oceanic areas exempt from these phenomena are the South Atlantic and the South Pacific.

Hurricanes have winds with speeds greater than 118 km/h, most of the time they are accompanied by torrential rains and tides, being the most powerful and strongest atmospheric phenomena on Earth and can last up to two weeks under adequate atmospheric conditions.

They usually classify them into 5 categories according to the Saffir-Simpson scale, based on wind speed and used in many countries; category 1 from 118 to 153 km/h, category 2 from 154 to 177 km/h, category 3 from 178 to 209 km/h, category 4 from 210 to 249 km/h, and category 5, greater than 250 km/h

A hurricane does not only mean an impact of the air, it can have secondary effects such as waves, landslides, floods and tornadoes, thus dragging water, dust, mud and heavy objects that cause human and material damage.

Today, there are radars, marine recording devices, and weather satellites that provide enough data to track the movements of every hurricane almost from its formation.

Although the best warning systems have prevented or reduced loss of life, meteorological elements, population growth, and human settlement in coastal areas continue to increase the risk of mortality. In addition, the material damage is still great in those areas.
