From playing war hero to displaying a rainbow of colors, here are some less well-known trivia tidbits about twisters.
By Melissa Breyer
Spawned from thunderstorms, the violent rotating columns of air known
as tornadoes can reach wind speeds up to 300 miles per hour and can
leave a path of destruction like few other forces of nature. Tornadoes
have kick. Like an angry Greek god, they can shatter buildings, drive
straws through trees, lift trains from tracks, and suck the water out of
streams.
The United States experiences around 800 tornadoes a year, resulting in
average of 80 deaths and more than 1,500 injuries. And while we all
know that tornadoes can transport young girls to Munchkin City, there’s a
whole slew of less well-known facts that are nearly as interesting.
1. F is for Fujita
Tornado strength is classified by the Fujita Tornado Scale, or F-scale
(and the Enhanced Fujita scale, or EF scale) developed by Tetsuya
Theodore Fujita of the University of Chicago. Known as "Mr. Tornado" to
his peers and the media, Fujita is also recognized for having discovered
microbursts and downbursts, which can pose serious danger to aircraft.
As a result of his work, pilot training across the world uses techniques
he developed.
2. Tornadoes are anonymous
Pity the tornado. While hurricanes, typhoons and cyclones are all
dignified with names, the tornado comes and goes with nary a moniker.
Why? Although some historic tornadoes are named relative to their
location, in general tornadoes are too short-lived to require naming.
For tropical cyclones (the family that hurricanes are included in) the
use of easy, distinctive names is quicker and less subject to error than
the antiquated, more unwieldy latitude-longitude identification methods
— which is especially important in communicating detailed storm
information to the media and between the multitude of coastal bases and
ships at sea. Tornadoes don't require such distinction.
3. Where tornadoes dare not go
Although the majority of the world’s tornadoes take place in the United
States, they have been observed on every continent except Antarctica.
4. Deadliest American tornado traveled for 220 miles
The deadliest tornado in United States history was the Tri-State
tornado, which made its debut on March 18, 1925. It began its journey in
Missouri and rolled across the land for nearly 220 miles, visiting
Illinois and Indiana along the way. In some areas, it left a path of
destruction almost a mile wide. The Tri-State tornado hurtled through
nine towns and splintered thousands of homes. The tornado caused 695
deaths and more than 2,000 injuries.
5. World’s most lethal tornado was in ... Bangladesh?
Oddly enough, the deadliest tornado in history wasn’t in the United
States. For those of us who equate the image of a dusty funnel roaming
across fields dotted with farmhouses, this may be hard to picture.
However, the Daulatpur-Saturia, Bangladesh Tornado which took place on
April 26, 1989, was extraordinary in its destruction. Death toll counts
were hard to calculate, but estimates indicate that some 1,300 people
were killed, making it the world’s deadliest tornado.
6. A tornado saved Washington, D.C.
During the burning of Washington in the War of 1812, a powerful tornado
struck northwest Washington and downtown on the day that the British
troops set fire to the Capitol, the White House and other public
buildings. Rain from the storm extinguished the fires, and more British
soldiers were killed by the tornado than by the guns of the American
resistance.
7. Southern and Northern hemisphere tornados spin differently
Tornadoes in the Northern Hemisphere, as viewed from above, rotate
counterclockwise 98 percent of the time. Southern Hemisphere tornados
rotate clockwise.
8. Tornados come in many colors
Tornadoes come in a wide array of colors, based on the environment in
which they form. Tornadoes in dry environments are nearly invisible,
while condensation funnels are generally gray to white. When traveling
over water, tornadoes can become opaque white or blue. Ponderous ones
that consume a decent amount of debris are usually darker and assume the
color of the debris. Great Plains tornadoes are often red because of
the tint of the soil. Lighting also affect the color of a tornado. A
back-lit tornado with the sun behind it will appear very dark, yet the
same tornado viewed from the other side may appear gray or brilliant
white. Sunset tornadoes can appear yellow, orange and pink.
9. Nothing says “go team” like a tornado
According to mascotdb.com, there are 113 high schools and colleges that use "Tornados" or a variation as their team nickname.
