Hurricanes
|
|
==========
|
|
|
|
Hurricanes get their start over the warm tropical waters of the North
|
|
Atlantic Ocean near the equator. Most hurricanes appear in late summer or
|
|
early fall, when sea temperatures are at their highest. The warm waters
|
|
heats the air above it, and the updrafts of warm, moist air begin to rise.
|
|
Day after day the fluffy cumuli form atop the updrafts. But the cloud tops
|
|
rarely rise higher than about 6,000 feet. At that height in the tropics,
|
|
there is usually a layer of warm, dry air that acts like an invisible
|
|
ceiling or lid.
|
|
|
|
Once in a while, something happens in the upper air that destroys this
|
|
lid. Scientist don not know how this happens. But when it does, it's the
|
|
first step in the birth of a hurricane.
|
|
|
|
With the lid off, the warm, moist air rises higher and higher. Heat
|
|
energy, released as the water vapor in the air condenses. As it condenses
|
|
it drives the upper drafts to heights of 50,000 to 60,000 feet. The cumuli
|
|
become towering thunderheads.
|
|
|
|
From outside the storm area, air moves in over the sea surface to
|
|
replace the air soaring upwards in the thunderheads. The air begins
|
|
swirling around the storm center, for the same reason that the air swirls
|
|
around a tornado center.
|
|
|
|
As this air swirls in over the sea surface, it soaks up more and more
|
|
water vapour. At the storm center, this new supply of water vapor gets
|
|
pulled into the thunderhead updrafts, releasing still more energy as the
|
|
water vapor condenses. This makes the updrafts rise faster, pulling in even
|
|
larger amounts of air and water vapor from the storm's edges. And as the
|
|
updrafts speed up, air swirls faster and faster around the storm center.
|
|
The storm clouds, moving with the swirling air, form a coil.
|
|
|
|
In a few days the hurricane will have grown greatly in size and power.
|
|
The swirling shape of the winds of the hurricane is shaped like a
|
|
dough-nut. At the center of this giant "dough-nut" is a cloudless, hole
|
|
usually having a radius of 10 miles. Through it, the blue waters of the
|
|
ocean can be seen. The hurricane's wind speed near the center of the
|
|
hurricane ranges from 75 miles to 150 miles per hour.
|
|
|
|
The winds of a forming hurricane tend to pull away from the center as
|
|
the wind speed increases. When the winds move fast enough, the "hole"
|
|
developes.
|
|
|
|
This hole is the mark of a full-fledge hurricane. The hole in the
|
|
center of the hurricane is called the "eye" of the hurricane. Within the
|
|
eye, all is calm and peaceful. But in the cloud wall surrounding the eye,
|
|
things are very different.
|
|
|
|
Although hurricane winds do not blow as fast as tornado winds, a
|
|
hurricane is far more destructive. That's because tornado winds cover only
|
|
a small area, usually less than a mile across. A hurricane's winds may
|
|
cover an area 60 miles wide out from the center of the eye. Another reason
|
|
is tornadoes rarely last as long as an hour, or travel more than 100 miles.
|
|
However , a hurricane may rage for a week or more (example: Hurricane
|
|
Dorthy) In that time, it may travel tens of thousands of miles over the sea
|
|
and land.
|
|
|
|
At sea, hurricane winds whip up giant waves up to 20 feet high. Such
|
|
waves can tear freighters and other oceangoing ships in half. Over land,
|
|
hurricane winds can uproot trees, blow down telephone lines and power
|
|
lines, and tear chimneys off rooftops. The air is filled with deadly flying
|
|
fragments of brick, wood, and glass.
