Q 01Which nickname is given to the broad swath of the central United States that twisters strike most often?
Tornado Alley
Tornado Alley is only a nickname, and forecasters call it misleading: the main threat shifts from the Southeast in the cooler months to the northern Plains by early summer.
Q 02Why do mobile-home parks seem to attract twisters in so many news reports?
Even weak tornadoes wreck them
Even weak tornadoes wreck them: a brief twister that would barely mark a sturdy house can blow a mobile home apart, so forecasters call the parks reliable indicators, not attractors, of tornadoes.
Q 03What is the rotating updraft in a supercell that often precedes a tornado called?
Mesocyclone
A mesocyclone is a rotating column of air a few miles wide inside a supercell, and spotting one on radar is a key sign a tornado may follow.
Q 04What type of cloud is most commonly associated with tornado formation?
Cumulonimbus
Cumulonimbus, the towering storm cloud, breeds the violent tornadoes, though weaker ones can hang from an ordinary cumulus.
Q 05What do forecasters call the Plains boundary where desert air from the west meets humid Gulf air and severe storms often erupt?
The dry line
The dry line marks the edge of the Gulf's moisture in spring and early summer; it usually pushes east during the afternoon and retreats west after dark, and storms fire along it.
Q 06A famous 1991 video of a TV crew riding out a tornado made which roadside spot a dangerously popular shelter?
A highway overpass
A highway overpass is among the worst places to shelter: the 1991 crew met only the fringe of a weak tornado, and people copying them under other bridges have been killed.
Q 07Tornadoes have been recorded on every continent but one; which is the exception?
Antarctica
Antarctica is the exception: tornadoes need warm, moist air, so they favor the middle latitudes and have been recorded on every other continent.
Q 08When the EF scale replaced the Fujita scale in 2007, what became of earlier US tornadoes' ratings?
They were left unchanged
They were left unchanged: the EF scale took effect on February 1, 2007 with no plan to re-evaluate older storms, so F5s and EF5s sit side by side in the record.
Q 09Besides the wind itself, what do forecasters call the biggest threat to life in a tornado?
Flying debris
Flying debris is the biggest threat to anything alive: winds that strong put cars in the air and turn broken glass into lethal missiles.
Q 10Tornado sirens are designed to warn which group of people?
People who are outdoors
People who are outdoors are the only intended audience: the sirens began as wartime air-raid alarms and were never built to be heard inside a closed-up house.
Q 11Which radar signature, formed as precipitation wraps a supercell's rotating updraft, warns a tornado may be forming?
Hook echo
The hook echo was first tied to a confirmed tornado by accident, in 1953: a crew testing a radar built to measure rainfall recorded an odd curl that turned out to mark a tornado on the ground.
Q 12Viewed from above, which direction do most tornadoes in the Northern Hemisphere rotate?
Counter-clockwise
Counter-clockwise, the same way hurricanes turn north of the equator; the rare tornadoes that spin the other way tend to be small and weak.
Q 13What do storm chasers call a non-supercell tornado whose spin starts near the ground and is stretched up by an updraft?
Landspout
Q 21'Tornado' is a reshaping of tronada, a word for a thunderstorm in which language?
Spanish
Spanish tronada, 'thunderstorm', comes from tronar, 'to thunder'; English reshaped the word, probably under the influence of tornar, 'to turn'.
Q 22Which country suffered the deadliest tornado on record, a 1989 storm officially blamed for about 1,300 deaths?
Bangladesh
Bangladesh's Daulatpur-Saturia tornado of April 26, 1989 tops the World Meteorological Organization's list; dense population and flimsy housing lie in the path of the country's violent pre-monsoon storms.
Q 23South America's tornado corridor, one of the busiest outside the United States, is centered on which country's plains?
Argentina
Landspout was coined because the funnel looks like a weak waterspout that happens to form over land; most are small and short-lived.
Q 14What does an approaching tornado most commonly sound like?
A continuous rumble like a train
A continuous rumble like a train is the classic description; some produce a whoosh like a waterfall, and many are audible only up close, so sound is no warning.
Q 15What does a 'Tornado Warning' mean?
One has been spotted or shown on radar
One has been spotted or shown on radar when a warning goes out; a watch is the weaker product, meaning tornadoes are possible over the next several hours.
Q 16Which storm is officially credited with the longest tornado track on record, 219 miles?
Tri-State, 1925
The Tri-State, 1925 tornado is credited with a 219-mile path, though researchers still debate whether it was one continuous tornado or a family of them.
Q 17What is the broad, abrupt lowering of a cloud base from which tornadoes sometimes form called?
Wall cloud
A wall cloud marks a storm's strongest updraft, and once it starts to rotate, spotters watch it as the place a tornado is most likely to drop.
Q 18The United States averages roughly how many tornadoes a year?
About 1,200
About 1,200 is the modern average; reports climbed sharply in the 1990s, when a new Doppler radar network and more spotters began catching tornadoes that once went unrecorded.
Q 19What is a short-lived swirling wind on a thunderstorm's outflow edge, not a true tornado, called?
Gustnado
A gustnado almost never connects the surface to the cloud base, which is why it is almost never counted as a tornado.
Q 20How long does a typical supercell thunderstorm last?
2-4 hours
2-4 hours is typical, against an hour or less for an ordinary storm cell, because a supercell feeds off a tilted, rotating updraft that keeps it organized.
Argentina's Pampas lie where cold, dry air from Patagonia and the Andes collides with warm, moist air from the north, breeding supercells, hail and tornadoes.
Q 24Which university's teams have been the Cyclones since 1895, when a newspaper likened its footballers to a tornado?
Iowa State
Iowa State earned the name after its footballers stunned Northwestern 36-0 and the next day's headline read 'Struck by a Cyclone'; tornadoes were then commonly called cyclones.
Q 25The widest tornado ever measured, 2.6 miles across, struck near which Oklahoma town in 2013?
El Reno
El Reno's tornado spanned 2.6 miles on mobile radar, yet it is officially rated only EF3: it crossed mostly open country, and surveyors found no damage to support anything higher.
Q 26Which storm chaser, famed for in-situ pressure probes, died in a 2013 Oklahoma tornado?
Tim Samaras
Tim Samaras died with his son Paul and colleague Carl Young when the tornado abruptly turned north, sped up and kept widening, overtaking their car before they could get clear.
Q 27A 2008 tornado damaged Atlanta's Georgia Dome while a tournament game in which sport was in overtime?
Basketball
Basketball's SEC tournament was in overtime when the EF2 ripped holes in the dome; the game was finished after an hour's delay, but the remaining games were moved to a much smaller college arena.
Q 28Mobile radar clocked record tornado winds of over 300 mph inside which 1999 storm?
Bridge Creek–Moore, Oklahoma
The Bridge Creek–Moore, Oklahoma tornado's record wind was read by a radar beam above ground level, not at the surface; its F5 rating rests on the damage survey, because the scale grades what a tornado destroys, not its wind.
Q 29Which rare NWS alert is reserved for a confirmed violent tornado bearing down on a populated area?
Tornado emergency
A tornado emergency is an upgraded tornado warning; a forecaster improvised the first one in 1999, sending it as a standalone statement apart from the warning itself.
Q 30In 1971, Ted Fujita introduced his tornado damage scale while a professor where?
University of Chicago
Fujita introduced the scale in 1971 at the University of Chicago, where he spent his career; Allen Pearson of the National Severe Storms Forecast Center added path length and width, hence Fujita-Pearson scale.
