What exactly is a hurricane

Hurricanes What Are They and How Are They Formed

Hurricane is the name of tropical cyclones, mostly in North and South America. The word “hurricane” itself is a distorted name of Huracan, the god of fear, of the South American Kiché tribe of Indians. In the Western Pacific Ocean, hurricanes are called “typhoons” (from Chinese «tai fung», which means «big wind»), “cyclones” in the Indian Ocean and the Bay of Bengal, “willy willy” off the coast of Australia, “willy wow” in Oceania, and “baguio” in the Philippines.

What exactly is a hurricane? The hurricane is an atmospheric vortex of large size with wind speeds up to 75 mph, and up to 124 mph in the surface layer. A hurricane or tropical cyclone is an atmospheric phenomenon that occurs over a warm sea surface and receives “fuel” from the fact that moist air rises, water vapor condenses as rain, and the drier air that is produced in this process descends. When the “fuel” runs out, the hurricane subsides.

How and where are hurricanes formed? Hurricanes form as cyclones in the inner tropical belt over the world’s oceans when water temperatures exceed 79 degrees Fahrenheit. A hurricane generates a perturbation (a sudden disruption of something’s normal course) that occurs when warm, moist air that comes into contact with the sea begins to rise. When it reaches high altitudes, it condenses, releasing heat. This causes other masses of hot air to rise and condense, creating a kind of chain reaction. Meanwhile, the air currents begin to rotate counterclockwise (clockwise in the Southern Hemisphere) due to the Earth’s rotation, taking the perturbation clouds with them. When wind speeds reach 81 miles per hour, it becomes a hurricane. Hurricanes in the Northern Hemisphere, due to the rotation of the Earth, move westward (from Africa towards America) with a speed that initially does not exceed 12-15 miles per hour.

How Are Hurricanes Formed Physical Processes

Where do most hurricanes hit Florida?

The birth and development of a tropical cyclone is a manifestation of the work of nature’s colossal heat machine. Well, how are hurricanes caused? At first, huge masses of water vapor from the ocean surface heated by the sun rise into the atmosphere. Thus, an area of low pressure is formed in the center of the future cyclone. It and the Coriolis force make the masses of humid air move in a spiral. More and more masses of humid air are drawn into the vortex, and the vortex itself begins to move. The vapor that has risen to a higher altitude condenses, and water falls in showers of rain clouds. The energy released during condensation warms the air, pulls it higher and pulls new masses of warm moisture from the sea surface. It takes a vast expanse of water, heated to 27 degrees to a depth of about half a meter, to bring this mechanism on line. As long as such conditions persist under the cyclone, it lives. As long as it comes on land, it will be deprived of its nourishment: the vortex energy is rapidly lost. A circular area of low pressure with relatively clear and calm weather – the so-called eye of the storm – is formed in the center of each tropical cyclone. The eye of the storm is bounded by a wall – an annular layer of clouds with maximum height. The most powerful downpours and strongest winds occur within the wall of the eye. You still can not understand and answer the question of how are hurricanes formed? In order to see the formation of hurricanes, we recommend you to watch how are hurricanes formed video.

Answers to the Most Interesting Questions

how are hurricanes formed
  • How many hurricanes are usually formed in a year? Usually, the typical year counts 9 hurricanes, 3 of which are major ones. Also, each year 12-15 storms occur with the given names. Answering the question of how many hurricanes are formed annually, we can not miss the fact that some years may be extremely active in terms of hurricane formation.
  • Is a hurricane a tornado? No, they are not the same phenomena. The differences between these two disasters are in size and duration. Hurricanes are bigger and last longer than tornadoes.
  • How long do hurricanes last? Usually the hurricanes last up to 24 hours, however, history know the case, when the hurricane has sustained itself for one month.
  • Do hurricanes get stronger at night? Yes. Scientists have proved that tropical cyclones tend to strengthen during the night time.
  • What happens when a hurricane hits land? It literally destroys everything on its path, bringing deaths and economic losses.
  • Where do sea animals go during a hurricane? The sea animals find themselves in deadly condition, as they have no option to survive hurricanes. When the hurricane ends, dead fishes and sea animals may be found far away from the sea or ocean.
  • How does a hurricane die? What eventually stops a hurricane? Is it possible to stop a hurricane? Unfortunately, there is no way to stop a hurricane. They tend to lose power as they move over land. Without warm ocean water to fuel their power, hurricanes eventually shrink in size and lose speed until they disappear altogether.
  • Who chooses the name of hurricanes? The World Meteorological Organization chooses the names of hurricanes, following the established rules of picking the names.
  • What are the 2020 hurricane names? The names were: Marco, Arthur, Laura, Bertha, Cristobal, Josephine, Teddy, Dolly, Paulette, Vicky, Nana, Edouard, Sally, Fay, Wilfred, Gonzalo, Isaias, Kyle, Hanna, Omar, Rene.
  • What was the first hurricane in history? Hurricane off the coast of Hispaniola in 1495. The earliest historical mention of the hurricane was made by the great explorer Christopher Columbus. During one of his voyages to the New World, Columbus encountered a tropical storm of such power that no one had ever seen before. To quote the explorer, the storm was so severe that he would not have wanted to experience it again under any pretext.
  • Where do hurricanes usually start? The natural phenomenon is formed over the tropical parts of the oceans (between 5-20° latitude). These include the southwestern part of the North Atlantic, the Pacific Ocean west of Mexico, the waters of the Philippine Islands, and the China Sea. In the Indian Ocean, these are the Bay of Bengal, the Arabian Sea, the waters off Madagascar, and the northwestern coast of Australia.
  • Where do hurricanes hit the most? The most dangerous are the Pacific islands of Vanuatu and Tonga, where people are threatened by hurricanes. A similar situation is observed in the Philippines, where the risk of hurricanes is also high. Almost all of Central America, Africa and part of the Southeast Asian countries are at risk.
  • What state has the worst hurricanes? The answer is the USA and hurricane Katrina.
  • What state has never had a hurricane? The lowest possibility of the hurricane is observed in Qatar and Saudi Arabia, as well as in Malta.
  • Do hurricanes hit Africa? Yes, they do, mostly the Western part of African continent.
  • What was the biggest hurricane? Hurricane Camille is considered to be the biggest one with the wind speed of 190 miles per hour.
  • What’s the worst category for a hurricane? There are 5 categories of hurricanes that increase in intensity from 1 to 5, with Category 4 and 5 hurricanes known to cause catastrophic damage.
  • What are the 4 stages of a hurricane? Category 4 hurricanes with wind speeds of 130-156 mph. Examples of Category 4 hurricanes are Hurricane Matthew, 2016; Hurricane Charlie, 2004.
