Lightning Phenomenon
Lightning is a natural phenomenon that occurs more often than we think it
does.
That streaking flash, followed by a loud rumbling noise, that makes
your knees
buckle is very dangerous because of its unpredictable striking
force. Being
struck by lightning can be deadly, so the more precautions you
take ahead of
time, the safer you are. Lightning not only affects us, it also
has a great
impact on our man-made structures and of course, our natural
surroundings.
According to Professor Martin Uman, one of the world’s
leading lightning
experts: Lightning is an effect of electrification within a
thunderstorm. As the
thunderstorm develops, interactions of charged particles
produce an intense
electrical field within the cloud. A large positive charge
is usually
concentrated in the frozen upper layers of the cloud and a large
negative charge
with a smaller positive are is found in the lower portions.
(4) This produces
what you see, a lightning flash, which may be "two or 300
feet long" (25).
The flash itself may be only as wide as a pencil, but
because it is extremely
hot, hotter than the sun, its glow appears to be very
wide to the human eye.
When lightning pushes the air from its path, it
expands it quickly causing a 2
loud explosion, which we call thunder (25).
William R. Newcott, part of the
National Geographic Editorial Staff,
describes lightning as a "river of
electricity rushing through a canyon of
air. Moving [SIC] fast as 100,000 miles
a second, lightning sears wild and
unstoppable through twisted channel as long
as ten miles," (83) he explained.
Lightning, being a natural occurrence, is
very unpredictable which makes it
even more dangerous. Martin Uman, director of
the University of Florida’s
Lightning Research Laboratory is quoted in Omni
saying, "A man was talking on
a telephone near Gainesville, Florida, when
lightning hit the wires. He died
instantly, electrocuted. Three or four people
die that way every year"
(Wolkomir 1). It is hard to believe that someone
could just die while using
the phone. You never know what will happen next when
it comes to lightning.
In fact, even in recent weeks, the state of New Jersey
was hit by lightning
causing various dangers. On June 6, 1996, a Sewaren oil
storage tank in
Woodbridge, New Jersey, was hit by lightning causing a ferocious
explosion.
This fire blazed for an unbelievable 28 hours. According to a staff
report in
the Asbury Park Press, two employees attempting to turn off the power
to the
area "suffered electrical burns, and were apparently the only
casualties"
(A1). Fortunately, the 3 other tanks did not explode, or a few
more
casualties might have resulted. Many people in the area felt and heard
the
force of the explosion. Staff writers add, that "nearby relaxing in his
boat
off Cliff Road, Rick Bothwell reported feeling the explosion, even on
the water.
I heard a bang and a whoosh. It felt like an explosion out of
a tube, he said"
(A1). Inland, nearby neighbors also felt the impact of the
explosion. "The
ground just rumbled from the front of house to the back, said
Richard Swallick,
who lives on West Avenue within a few hundred yards of the
tank field" (A1).
Experts are very unsure as to what caused this almost
disastrous explosion. Also
in this article, "Elaine Makatura, a spokeswoman
for the state department of
Environmental Protection, said it was too
early to speculate on what the
environmental impact of the blaze will be"
(Staff Report A5). In otherwords,
they don’t know if any harmful chemicals
were released during the blaze.
Contaminants in the air could cause a
serious problem for neighbors of the gas
store area. After something like
this happens, the question that comes to mind,
is can lightning strike twice?
Well, according to Bernhard Warner, a staff
writer for the Asbury Park Press,
there was a smaller explosion in Linden, New
Jersey, at the Tosco
Refining Co. shortly before the one in Woodbridge exploded
(A5). A 4 manager
at the refinery would not say whether lightning caused the
fire, because it
is still under investigation. It seems the more things, we
learn about
nature, the more questions arise. Bob Friant, a spokesman for the
State
Department of Community Affairs, is quoted in the Home News and Tribune,
by
Sean P. Carr, saying "we have never been able to conquer Mother Nature,
and
we never will be" (B1). He has a real optimistic point of view, huh.
Although,
after Carr points out that their are "thirty-five fuel storage
tank
facilities, some of the dozens of tanks each store millions of gallons,
dot the
Shore of Central and Northern New Jersey waterways," (B1) the
chance of this
happening again seems likely. Furthermore, Martin Uman
continues saying, "At
any moment, planet wide, about 2,000 thunderstorms are
in progress. Each storm
generates a flash every 20 seconds" (4). That is
unbelievable. Now I can
understand how there are so many deaths and injuries
from people being struck by
lightning. The more thunderstorms, the more
chances lightning will strike. If
you give lightning enough chances, it is
bound to hit something. In the time it
takes you to read this sentence,
lightning has flashed more than 500 times (4),
Uman notes. Facts like
that are really amazing to me. How could lightning have
just flashed 500
times? This is because most of the lightning flashes we see
are
cloud-to-ground strokes, but they "compromise only 5 about 20 percent
of
lightning" (4). Much more frequent are flashes within clouds.
Although
lightning kills many Americans every year, luckily some victims of
lightning
hits have lived to tell about the experience. More than a year
after lightning
nearly killed him during football practice, Tony Trice still
does not want to
talk about it (Newcott 90). According to eyewitnesses in
Burtonsville, Maryland:
"They saw a bolt tear a hole in the high
schooler’s helmet, burn his jersey,
and blow his shoes off. Toy’s breathing
stopped, but he was resuscitated on
the spot" (90). It is unbelievable that
this teenager survived after being hit
by one of nature’s unpredictable and
deadliest forces. How is it possible
someone could survive after being struck
by lightning? Researchers at the
University of Queenland in Australia
have traced the path followed by lightning
when it enters a living creature
(Dayton 1) and according these researchers:
simulated lightning strikes on
anaesthetized sheep showed that lightning first
enters the body orifices and
then flow along the blood vessels and cerebrospinal
fluid (CSF) pathways.
Since the CSF pathway narrows near the brainstem, this
part is hit hardest,
resulting in cardiac and respiratory arrest. Since the
heart can restart
itself because of autonomous control, fatality usually results
from
respiratory failure. (1) This shows the importance of
mouth-to-mouth
resuscitation for lightning victims. 6 I almost witnessed
someone being struck
by lightning, but luckily they were not. It was during a
soccer tournament that
I was playing in, about nine years ago. All of a
sudden, the sun was hidden
behind the clouds and the sky turned a dark
purplish color, and then it
downpoured. The sky rumbled with fierce thunder
and you could see a couple of
lightning flashes. The tournament was at a high
school, so everyone ran to the
school for safety. My father was with me, and
as we headed towards the school,
we saw a bright flash of lightning strike a
tree about a mile from us and split
it in half, starting a little fire. There
were two kids from my team that were
around 50 feet away from the tree and
they stood there frozen in fear. My dad
told me to keep going. Then, he went
back and had to literally carry them to
safety because they were so scared.
Fortunately, no one was any closer to that
tree or they would have been
seriously injured or killed that day. Golfers are
prime targets for
lightning, because they tend to either stand in open grassy
areas or huddle
under trees while playing their game. Also, they use umbrellas
which attract
lightning to them because of the metal point on top. In addition,
they hold
metal golf clubs which increase their chances of being struck by
lightning.
"A scored pattern on the fifth green at Phalem Park Golf course in
St.
Paul Minnesota, defied ground zero when four golfers were injured,
one
fatally, by 7 a June 1991 strike" (Newcott 89). I guess that kind of
proves
that golf can be a dangerous sport, especially during a thunderstorm.
In the
film, Lightning, directed by Linda Gorman, a golf legend, Lee Trevino
describes
his experience of being hit by lightning, while playing in a
tournament in 1975.
Trevino says: The sensation that I got was, I knew
that something was wrong. It
did not just go pow, and it was over. I felt it,
and I started shaking. The next
thing I knew, I started to hear a ringing
sound in my ear, like a ball-peen
hammer. Then all of a sudden, the next
thing I know is look at my feet and now
they are in the air. Now I’m off the
ground... its got me all stretched out.
At the time, I guess it stops
your heartbeat and I’m gasping for air. The next
thing I knew, is I woke up,
and I was all doubled up. My left arm was under my
body... (Lightning) In
listening and watching Trevino speak, I could see his
confusion and
uncertainty of what was happening to him.. I am sure to this day,
when he is
golfing on the green during a thunderstorm, he becomes reminiscent of
his
previous experience with lightning. 8 Tall man-made structures have
been
known to attract lightning. According to The New Book of Popular
Science,
engineers in 1935 set up a device inside the Empire State Building
in New York
City, to find out how the building handles being struck by
lightning in the
experience. In the film Lightning, one source noted that
this famous building is"struck more than twenty times each year" (Lightning).
The special rod at
the top of the building was connected to this device by
steel. This would allow
a small amount of the current to safely deflect from
the rod to their machines.
Also photographs were taken from a small
building to provide proof of this
experiment. They concluded from their
studies that it is possible for lightning
to strike twice in the same place
(142-143). "The empire state tower has been
struck by lightning as many as 42
times in one year. It was hit 12 times in a
single storm, and on one
memorable occasion, 9 times in 20 minutes," (142-143)
which proves their
studies to be accurate. Yet, after all those strikes, there
was no damage to
the building. Nature itself is also affected by lightning.
Lightning is a
cause of forest fires, which of course, may be devastatingly
destructive.
According to The New Book of Popular Science: It also causes a
great deal of
damage as a result of heating and expansion. When it passes
through wood, for
example, the 9 enormous current heats the wood and causes it
to expand many
many times. As a result, the wood is converted into vapor, and
this adds to
the general effect of expansion. (143) It is interesting that
Mother
Nature can create lightning, but she can also destroy a part of herself
in
the process. All of us must respect lightning. It is very dangerous and
it
kills! We do not have to be afraid of it, though. We can protect ourselves
from
lightning by observing some basic lightning safety rules. According to
my
research, I have learned that one should keep away from conductors such as
metal
and water, as well as tall trees. When inside a home avoid using the
telephone
except for emergency. You will not see me talking with my friend
during a
lightning storm, not after hearing about the man getting
electrocuted while
talking on the phone. If outside, with no time to reach a
safe building or an
automobile, follow these rules given by Martin Uman: Do
not stand underneath a
natural lightning rod such as a tall isolated tree in
an open area. Stay away
from wire fences, clotheslines, metal pipes, rails,
and other metallic paths
which could carry lightning to you from some
distance away. If you are
hopelessly isolated in a level field or prairie and
you feel your hair stand on
end, indicating lightning is about to strike,
drop to your knees and bend
forward, putting your hands 10 on your knees. Do
not lie on the ground!!! (95)
Lightning does not choose its victims or
target. It just happens. For the many
fatalities, those people were just in
the wrong place at the wrong time. It is
alright to be curious about
lightning, but do not be stupid. Take the proper
precautions or you may just
be another statistic. Remember you cannot predict
when or where lightning
will strike, but you can be aware of the possibility. It
might be well, also
to recall this passage from "Playing with Lightning",
written by a lightning
stalker, Karl B. McEachron, quoted in The New Book of
Popular Science:
"If you heard the thunder, the lightning did not strike you.
If you saw
the lightning, it missed you; and if it did strike you, you would
have known
it" (144). So, in otherwords, you can not predict when or where
lightning
will strike, but you will definitely know it, when it strikes
you.
