Hurricane Florence: What is a hurricane? What are the hurricane categories?

Hurricane Florence is the latest major storm system that has invaded the US, not long after tropical storm Gordon landed in Florida.

The hurricane is a classic term for the hurricane season in the Atlantic, where the coastal and mainland states of the United States of America are hit by a high number of storm systems.

Hurricane season is also for the Pacific, where hurricanes and typhoons are currently spreading their roots, Hawaii had already entered with a troublesome Hurricane Lane, while the Philippines and Hong Kong soon see the arrival of Typhoon Mangkhut.

The season will last until fall and end around November, after a seasonal barrage of hurricanes ranging from a category 1 to a fearsome category 5 and weighing the scales with winds in excess of 150 mph.

What is a hurricane?

Hurricanes exist in the same way as a tornado and are the product of perfect weather conditions that lead to dangerous swirling wind and rain masses.

The scientific name for a hurricane is a tropical cyclone, a name for gravure weather formations that originate in the Atlantic Basin.

Low-pressure systems are identified by rising warm air and changeable weather, known in the Atlantic as a tropical disorder.

Tropical disturbances see the air rising and then blowing counterclockwise as they rise and cool, forming clouds and precipitation.

From here, the storm has the opportunity to develop into a tropical depression in which the storm begins to organize.

Depression is defined as an area of ​​rotating thunderstorms with wind swirling around 38mph or less.

Depression will build up when conditions are perfect, with high humidity and warm seas that allow it to keep coming.

A tropical storm can form when the winds successfully reach 39 miles per hour and then become a hurricane at 74mph.

These tapes are important in understanding how powerful a hurricane can be and how prepared the public should be as it develops.

What are the hurricane categories?

Hurricanes are defined from their lowest to highest in a collection of five "categories" on the Saffir-Simpson scale.

Developed by civil engineer Herbert Saffir and meteorologist Robert Simpson, this scale has been in use since 1973 and classifies every storm that seethes in the Atlantic and Pacific Oceans.

According to standards of this magnitude, a hurricane takes on its form when a system reaches wind speeds of up to 100 km / h and is reevaluated from there every time it strengthens to a certain level.

Each gang has a severity ranging from dangerous to catastrophic damage.

Category 1 on the Saffir-Simpson scale warns that "very dangerous" winds with winds between 74 and 95 mph will cause damage.

The next category, category 2, sees winds of 96-110mph and warns that winds are extremely dangerous, with well-designed properties that suffer damage to the roof and façade.

Category 3 on the scale heralds the beginning of "big" hurricanes and warns of "devastating" damage caused by 111-129mph of wind, where electricity and water could be unavailable for days or weeks.

Catastrophic damage is reported at Category 4 level, where winds of 130-156mph scatter trees and make areas uninhabitable.

The final stage, category 5, is a hurricane with winds of 156 or more, where a high percentage of well-built homes are flattened and the area rendered uninhabitable.
