How are hurricanes formed? what causes a hurricane like Katrina, Ivan, and how do they build to the point of devastating entire towns or cities?
Why do hurricanes only seem to form in certain areas of the world like Florida so often but never seem to form in other places?
First of all, let’s tackle the question “What are Hurricanes and How Are Hurricanes Named??”.
How Are Hurricanes Named?
Are you wondering “how are hurricanes named?” or how hurricane Katrina, Ivan, Floyd and other devastating storms got their name? Then you’ve come to the right place! If you want to know how hurricanes are named, then we must go back to the storm that precedes the hurricane.
The storm only becomes a hurricane after a storm’s wind speed 74 MPH is reached.
That storm is usually named before the hurricane is actually classified as such. When 74 MPH wind speed is reached it is classified as a hurricane and any name that storm had before it was classified as a hurricane is given to it by default.
Hurricanes are named currently by the world meteorological organization who picks them from a list of names, but they weren’t always named by them. In world war 2 hurricanes were named out of necessity so that we were able to tell one storm from another.
They were named alphabetically, from A to Z. Because the soldiers missed their loves ones back home, they gave the then mostly female names until 1979 when male names began to be used when hurricanes were named.
Although names may be re-used for future hurricanes or storms, the names of a severe or particularly devastating hurricane are not re-used again. For fear of jinxing the next big hurricane into existence they are taken off the list. 40 names have been taken off the list since 1954.
Causes: How are hurricanes formed
Three things are necessary for a hurricane to be formed:
- Warm ocean water has to be present or close by for a hurricane to begin to form (At least 80 degree’s Fahrenheit or 27 degrees Celsius).
- Moist air also has to be present for a hurricane to be formed. Warm evaporated ocean water feeds the hurricane moist air
- Lastly, tropical winds blowing about 73 miles per hour in the same direction and speed are needed for a hurricane to form.
