What's a Hurricane?

hurricane is a very strong storm. These storms usually start over the
Atlantic Ocean in the tropics. The tropics are around the equator.
Hurricanes only form in the summer and early fall months. They need a
lot of warm, moist air to form. Hurricanes start at a place over the
ocean where there's low air pressure. Most hurricanes start over the
Atlantic Ocean. Because the pressure is low, the air rises. Cooler air
from outside this low pressure spot rushes in to take its place. The
moving air begins to spin like a tornado. The center of the hurricane
is a calm part called the eye. The winds spin around this eye. The eye
wall is near the eye. The eye wall is where the winds are strongest.
These winds can be faster than 200 miles per hour! As long as the
hurricane stays over warm water it will keep growing stronger. The
winds pick up more warm, moist air over the ocean, feeding the storm.
This drives the winds even faster. When a hurricane passes over land or
cooler water, it starts to lose energy. Still, hurricanes can do a lot
of damage. They are very powerful storms!Copyright © 2012 edHelper
