How did they form? How were they different from tornadoes and other big storms? He began reading—and he couldn’t stop. First, Kennedy discovered, hurricanes only form over warm ocean water. The storms are only called hurricanes if they
take shape over the Atlantic and the northeastern Pacific Oceans. Over the South Pacific and Indian Oceans, they are called cyclones. Over the northwestern Pacific Ocean, they are known as typhoons. 10 rm over Hurricanes can only fo warm ocean water. 11 All hurricanes begin as tropical storms. They need warm water that is 79 degrees Fahrenheit (26 degrees Celsius) or higher to form. As the water evaporates into the warm air, the air begins rising. It cools and condenses into large clouds.
Air over the ocean rushes in to replace the rising air, creating winds. Earth’s rotation causes these winds to form a large swirl. 12 g warm air cools and Clouds form when risin starts to condense. 13 Trouble on Land “What are you reading that is so interesting?” Kennedy’s friend Sam asked. “Listen to this,” Kennedy replied. “Scientists put hurricanes in categories from 1 to 5, from least destructive to most. A hurricane at any level will still cause damage to the communities it hits.”
