Last
time we talked about the hurricane, how and where it formed (over warm ocean
waters). We mentioned hurricanes
generally form from June 1 through November 30th in the Atlantic and
May 1 to November 30th in the Pacific Ocean. We talked about the surge of water that comes
ashore with a hurricane, the storm surge and then mentioned the scale that
measures the strength of hurricanes called the Saffir-Simpson. Today we are going to investigate these
storms a little more.
I
get asked this question many, many times.
What is the difference between a hurricane, a typhoon and a
cyclone? The answer is, basically
nothing except location. In the Atlantic
Ocean, the Gulf of Mexico and the eastern Pacific Ocean, these tropical storms
are known as hurricanes. In the western
Pacific Ocean, these same storms are called typhoons and in the Indian Ocean,
the Bay of Bengal and Australia these storms are called cyclones. So, same type
storm, just named differently in different parts of the world.
Years
ago, there were no satellites, no radar, no TV, not even radios. The major hurricane that hit Galveston, Texas
in 1900 took the public by complete surprise.
There were a few reports being spread around that Cuba had a hurricane
but that “news” was dismissed as hearsay.
While this storm was approaching Galveston, many curious folks went to
the seashore to examine the angry seas.
Finally, the storm surge arrived on shore and washed thousands of
onlookers out to sea. In all, when the
storm had passed, 16,000 people had lost their lives. Today, that would never happen. We have come so much further than back in
those days. In the 1950’s hurricane
hunter planes began flying into the eyes of hurricanes. One of my high school students, who was part
of the weather club I organized at the high school, is now the director of
research of the national hurricane center.
He is in charge of the hurricane hunter division. He has asked me numerous times to fly with
him into a hurricane on the hurricane hunter plane. I refuse each time because I am chicken. He does tell about some harrowing experiences
he has had, but insists they have never had a passenger death or lost a
hurricane hunter in over 60 years of flying into hurricanes. My student tells
of his experiences, saying the flight is 95% boredom and 5% sheer terror. Anyway, he has flown though the eye of
hurricanes over 300 times. These
hurricane hunter planes usually fly into, through and around the eye of the
hurricane at all levels to get very accurate readings concerning the storm and
then send all the data back to the hurricane center where it is put into
computers to improve the forecast of the future speed, strength and direction
of the storm.
Of
course, also being relayed back to the hurricane center are pictures of the
storm from space. Satellite imagery has
improved greatly over the years. As the
storm gets closer to land, radar is then utilized. Now they can get an exact fix on the location
of the storm and track its exact movement.
Forecasts are then made and ready for distribution. Again, one of my students from the high
school weather program is the executive vice president of the largest weather
corporation in the world. Millions and
millions of people are notified immediately by radio, TV, and internet that a
storm is threatening their location.
Mandatory evacuations are issued in areas that are in eminent
danger. Never again will a hurricane
“sneak up” on a location. When storms
are just beginning, they are picked up by the satellites and followed. When then get closer to land, the planes fly
out to examine them. Then radar goes
into play. Computer programs forecast
future movements…. we are well protected…. follow the watches and
warnings.
Usually
a watch means a weather situation is possible in the next 12-36 hours. A warning means a weather situation is
expected in the next 24 hours. For
example, a hurricane warning means hurricane conditions are expected in your
area within 24 hours and all precautions should be taken immediately, including
evacuation if necessary. Within the last
10-20 years, beachfront property has become a very popular location. A major hurricane, category 4 or 5 will be
catastrophic. Some people will refuse to evacuate, others may be unable to
evacuate. Time will tell how this is
going to work out. There are indications
a major hurricane may threaten the east coast of the United States from
September 17th to 19th, 2015.
That’s this year! Of course,
making an outlook like this is like shooting a bullet out of the sky with
another bullet, but we will watch.
