Q 01What is the most common name for the region in the central United States known for frequent tornadoes?
Tornado Alley
Tornado Alley is the nickname for the central Plains from Texas to the Dakotas, where dry air off the Rockies meets Gulf moisture beneath strong upper-level winds.
Q 02What scale is primarily used to rate the intensity of tornadoes in the United States and Canada?
Enhanced Fujita
The Enhanced Fujita scale rates a tornado from the damage it leaves behind, matched against 28 damage indicators, rather than from any measured wind speed.
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
Weaker tornadoes can hang from an ordinary cumulus, but the violent ones come from towering thunderstorm clouds.
Q 05Which U.S. state experiences the most tornadoes annually on average?
Texas
Texas averages well over 100 tornadoes a year, the most of any state, largely because of its sheer size; Kansas is a distant second.
Q 06Tornado ground movement ranges from almost stationary up to more than how many miles per hour?
60 mph
60 mph is the top of the quoted range, though forecasters admit there are no detailed statistics on forward speed; the winds inside can top 300 mph.
Q 07A widespread event of multiple tornadoes occurring over a short period across a large region is known as a what?
Tornado outbreak
A tornado outbreak is many tornadoes spawned by the same weather system, often across several states over a period of hours or days.
Q 08On February 1 of which year did the US National Weather Service adopt the EF damage scale?
2007
The Enhanced Fujita scale took effect on February 1, 2007, rating damage against 28 indicators such as building type; tornadoes rated before that date kept their old Fujita ratings.
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 10Which of the following terms describes a tornado that forms over water?
Waterspout
A waterspout counts as a tornado by definition, but it is left out of official U.S. tornado statistics unless it comes ashore.
Q 11Which radar signature, formed as precipitation wraps a supercell's rotating updraft, warns a tornado may be forming?
Hook echo
The hook echo is drawn when the rear-flank downdraft drags rain around the updraft base, curling the tell-tale shape on the radar display.
Q 12Viewed from above, which direction do most tornadoes in the Northern Hemisphere rotate?
Counter-clockwise
Counter-clockwise, like the hurricanes above them, with anticyclonic exceptions that are usually weak waterspouts or landspouts.
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 21The word 'tornado' traces back to a Spanish word meaning what?
Thunderstorm
Tornado comes from Spanish tronada, 'thunderstorm', from tronar, 'to thunder'; the r and o later swapped places under the influence of tornar, 'to turn'.
Q 22Which country suffers the most tornado deaths per year, an average of about 179?
Bangladesh
Bangladesh averages about 179 tornado deaths a year, the most of any country, because dense population and flimsy housing lie in the path of violent pre-monsoon storms.
Q 23The 1989 Daulatpur–Saturia tornado, the deadliest ever recorded, killed roughly how many?
1,300
World Meteorological Organization figures also put the injured at about 12,000 after the tornado swept through Manikganj District on April 26, 1989.
Landspout was coined for its resemblance to a weak Florida Keys waterspout 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 holds the U.S. record for the longest continuous tornado track, 219 miles?
Tri-State, 1925
The Tri-State, 1925 tornado stayed on the ground for 219 miles across Missouri, Illinois and Indiana on March 18, 1925, the deadliest single tornado in U.S. history.
Q 17What is the broad, abrupt lowering of a cloud base from which tornadoes sometimes form called?
Wall cloud
A wall cloud marks the strongest updraft beneath a cumulonimbus, the part of the storm where a tornado may spin up.
Q 18Approximately how many tornadoes occur in the United States annually on average?
1,000-1,200
The United States records 1,000-1,200 tornadoes in a typical year, far more than any other country; Canada is a distant second.
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
A typical supercell lasts 2-4 hours, far longer than the 30-60 minutes of an ordinary thunderstorm, because its tilted, rotating updraft stays clear of its own rain-cooled downdraft.
Q 24Roughly what share of Northern Hemisphere tornadoes spin clockwise, the 'wrong' way?
About 1%
About 1% of Northern Hemisphere tornadoes are anticyclonic, spinning clockwise; most are weak landspouts, gustnadoes or small satellite tornadoes beside a large cyclonic twister.
Q 25The widest tornado ever measured, 2.6 miles across, struck near which Oklahoma town in 2013?
El Reno
The May 31, 2013 El Reno tornado was measured at 2.6 miles wide by mobile radar, beating the previous 2.5-mile record from 2004; it was rain-wrapped and multi-vortex.
Q 26Which storm chaser, famed for in-situ pressure probes, died in a 2013 Oklahoma tornado?
Tim Samaras
Tim Samaras, whose TWISTEX team placed pressure probes in tornado paths, died with his son Paul and partner Carl Young in a 2.6-mile-wide Oklahoma tornado on May 31, 2013.
Q 27A 2003 probe near Manchester, South Dakota, logged a record tornado pressure drop of how many hPa?
100
The drop happened in under a minute and is in Guinness World Records; the 850 hPa reading is the lowest surface pressure ever measured.
Q 28Mobile radar logged the fastest tornado wind ever, about 302 mph, during which 1999 tornado?
Bridge Creek–Moore, Oklahoma
The May 3, 1999 Bridge Creek–Moore, Oklahoma tornado produced a Doppler on Wheels wind reading of about 302 mph; a 2021 reanalysis of the data nudged it up to roughly 321 mph.
Q 29An NWS 'tornado emergency' is an enhanced version of which alert?
A warning
A tornado emergency is an upgraded tornado warning for a confirmed violent tornado bearing down on a populated area; the first was issued for south Oklahoma City on May 3, 1999.
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.
