AUSTIN (KXAN) – Hurricanes are the most powerful storms on earth. Just one
of them can release as much energy as 10,000 nuclear bombs. But how exactly do
The path of a hurricane
hurricane usually starts its life near the coast of Africa. First, winds blow
clusters of thunderstorms off the coast and into the open ocean. These are
called African Easterly Waves, or AEWs.
storms travel westward, winds blowing across the warm ocean water evaporate
some of that water into the air. That moist air rises higher into the
storm, where it condenses into clouds.
happens, heat is released into the atmosphere. This is called latent heat
release. It’s a very important part of tropical cyclogenesis, because as this
process repeats itself, it generates more and more warm air which rises into
the center of the storm.
where things get intense. All of that rising warm air creates a void at the
center of the storm. Wind then rushes in to fill that void, and all that
fast-moving wind begins to spiral due to the rotation of the earth.
What is storm surge?
high wind and lower pressure pull massive amounts of ocean water toward the
center of the storm, raising the level of the ocean underneath the eye. This is
called storm surge. The hurricane carries this bubble of water onto the shore,
causing massive flooding. This is the most dangerous part of a hurricane,
hurting far more people than the wind.
hurricane approaches, it’s important to go to higher ground in a sturdy
shelter. If there is an evacuation notice, it’s best to just leave.
