How hurricanes are named and categorized ?
As Hurricane Florence approaches the east coast of the United States, where it is expected to cause a dangerous rise in water levels and torrential rain, some may wonder what the secret behind the designation is, and the names of other hurricanes that strike across the world.
The ocean front is stormy as it reaches a speed of 39 miles per hour and is officially classified as a hurricane if it reaches 74 miles per hour.
The hurricanes are divided into five categories according to their speed, The first category is between 74 and 95 miles per hour, causing moderate damage, while the fifth category is more violent, moving at 157 miles per hour.
The hurricanes are named after people like Matthew, Olivia, etc., until the turn of the century, initially limited to female names. This is due to the attempt to distinguish hurricanes from others in any system. It is easier to remember than any Serial numbering, so meteorologists, coast guards and shipbuilders can trade information without fear of misunderstanding.
The first hurricane was usually given a name beginning with the letter “a”, “b”, etc.
In 1953, the nomination process became more organized by the US National Hurricane Center, which has compiled lists of names that may recur every few years for storms in the North Atlantic, Gulf of Mexico and the Caribbean.
In 1978, male names were introduced for the first time to label storms in the North Pacific and then Atlantic storms the following year, with the aim of making the process less biased to women after complaints were received.
The names of males and females are now rotated annually, through six lists of 21 each, while the names of hurricanes that caused future victims are excluded, in respect of the feelings of those who lost their loved ones, according to the World Meteorological Organization. For example, the name Katrina will not be used again after the extensive destruction it caused in the Gulf Coast and the South of the United States in August 2005.
The Tropical Cyclone Committee of the World Meteorological Organization (WMO) is naming the storms in the Atlantic Ocean, while the US National Hurricane Center is naming those in the Pacific Ocean.
The hurricane “Florence”, which is approaching days from the east coast of the United States to the second degree, and said «National Hurricane Center» was detected about 520 km southeast of Myrtle Beach in South Carolina.
The center will be close to the coasts of North and South Carolina on Thursday and then pass near or on the coast of South Carolina and East Carolina on Thursday night and on Friday, the center said.
