How Do Hurricanes Form?
2. Warm Water
Another ingredient needed for a hurricane to form is warm water, and lots of it. This is why hurricanes form in the tropics, and the technical term for a hurricane is a tropical cyclone. The water will need to have a temperature of at least 26 degrees Celsius at a depth of 50 meters or more. As a tropical wave moves over the warm waters, the warmth will cause warm air to rise up into the storm.
This, in turn, will cause an area of low pressure to form beneath the storm, and this will cause even more air to come rushing in.
