Basically, hurricanes arefueled by two 18 : heat and water. Hurricanes are seeded over the warm waters above the equator, where the airabove the ocean’s surface takes in heat and moisture. As the hot air 19 , it leaves a lower pressure region belowit. This process repeats as air from higher pressure areas moves into the lower pressure area, heats up, and rises, inturn, producing swirls in the air. Once this hot air gets high enough into the 20 , it cools off and condenses intoclouds. Now, the swirling vortex of air and clouds grows and grows and can potentially become a thunderstorm.
