What conditions are needed?
In order for a hurricane to form, there must be warm temperatures, low air pressure, tropical winds, and moist ocean air.
Where and when do they form?
Hurricanes form over water in the tropics where the water is warmer than 80 degrees Fahrenheit or 27 degrees Celsius and in between the latitudes of 8 and 20. Most of them form in hurricane season, which is from June to November.
What powers the storm?
They are fueled by heat energy that is released when water vapor condenses into rain. Hmm... does that mean that the more heat energy there is, the more strength the hurricane will have?
Stages a Hurricane Goes Through
1. Tropical Wave-a westward moving area of low air pressure
2. Tropical Disturbance- formed when moist, warm air over the ocean rises into the area of low air pressure and cold air from above replaces it; produces strong winds, heavy rain, and thunderclouds
3. Tropical Depression- when air pressure drops and there are sustained winds at a speed of up to 38 mph
4. Tropical Storm- when cyclonic winds have sustained speeds from 38-73 mph
5. Hurricane- when there are sustained winds of over 73 mph
The End
When a hurricane travels over land
or cold water, its energy source is gone.
This causes the storm to weaken and quickly
die.
