All about hurricanes: How are they formed and where do they come from?
Hurricanes often affect the U.S. coast. May it be hurricane Irma, Harvey, or Jose, the damage caused is immense.
Where do these hurricanes come from?
Interestingly, the majority of these hurricanes come from Africa. Sometimes they come from a point off the coast of West Africa which is situated near Cape Verde. The next question is about the formation of hurricanes. Hot dry air and cool moist air bring about a clash in climatic conditions. Further, high-altitude winds form as a result of this climatic clash. These winds are powerful and are known as African Easterly Jet.
Another point of origin of hurricanes is the Sahara desert which is hot and arid.
The winds formed are so powerful that they have the ability to create an intense hurricane that then reaches the United States of America. They move from East to West. The winds are at their peak during the month of September. They mix with warm water near the Equator post which warm moist air can be witnessed over the Atlantic. This can then lead to the formation of a thunderstorm with rotating winds. When the wind speed of 74 mph forms a Category 1 hurricane, a Category 5 hurricane is formed when the wind speed is 157 mph which can be extremely violent and dangerous. Most hurricanes reach the east coast of the U.S.A. Some hurricanes continue to live on in the Pacific. An example is Hurricane Iselle which hit Hawaii in 2014.
The most interesting fact about a hurricane that brings a lot of rain and wind along is that it comes from one of the driest places on Earth like the Sahara Desert.
