Hurricane (hurricanes)

Hurricane (hurricanes)

A hurricane is the name of a tropical cyclone with sustained winds of 117 km / h or more that develops in the North Atlantic, Caribbean Sea, Gulf of Mexico and east of the North Pacific. This same phenomenon is known as typhoon in the Western Pacific and as a cyclone in the Indian Ocean.

The term hurricane comes from the Arawak name attributed by the ancient inhabitants of the Caribbean islands to this type of atmospheric phenomena.

Hurricanes usually originate at the end of the summer, mainly in the months of August and September, with the production of winds of extraordinary violence, torrential rainfall and storms.

A hurricane is formed when the warm and humid saturated air of the equatorial calm zones rises in the form of a column between 10-20 km in diameter, which begins to rotate. This column known as mesocyclone disappears most of the time, but in cases where its rotation continues it can form a cyclone, with a sharp decrease in atmospheric pressure and the increase in air velocity towards its center.

Thanks to the Doppler radar that measures wind speed and direction in any storm, hurricanes have been studied in greater detail. In general, the winds developed in a hurricane move at a slower speed at its ends, with a progressive increase in its speed towards internal areas, except for its center or eye of the hurricane, where they almost disappear completely.
