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 formed?".
What Causes A Hurricane To Form?
- 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
