2011: Year of the Tornado
Posted by: Dr. Jeff Masters, 7:25 PM GMT en Diciembre 27, 2011 +45
The year 2011 will forever be known as Year of the Tornado in the U.S. A series of violent severe storms swept across the Plains and Southeast U.S., bringing an astonishing six billion-dollar disasters in a three-month period. The epic tornado onslaught killed 552 people and caused $25 billion in damage. Three of the five largest tornado outbreaks on record hit in a six-week period, including the largest and most expensive tornado outbreak in U.S. history--the $10.2 billion dollar Southeast U.S. Super Outbreak, April 25 - 28. Even more stunning was the $9 billion late-May tornado outbreak that brought an EF-5 tornado to Joplin, Missouri. The Joplin tornado did $3 billion in damage and killed 158 people--the largest death toll from a U.S. tornado since 1947, seventh deadliest tornado in U.S. history, and the most expensive tornado in world history. In a year of amazing weather extremes, this year's tornado season ranks as the top U.S. weather story of 2011.


Video 1. Remarkable video of the tornado that hit Tuscaloosa, Alabama on April 27, 2011. Fast forward to minute four to see the worst of the storm.

A record six EF-5 tornadoes confirmed in 2011
Six top-end EF-5 tornadoes hit the U.S. in 2011, tying this year with 1974 for the greatest number of these most destructive tornadoes. The EF-5 tornadoes of 2011:

1) The April 27, 2011 Neshoba/Kemper/Winston/Noxubee Counties, Mississippi tornado (3 killed, 29 mile path length.)

2) The April 27, 2011 Smithville, Mississippi tornado (22 killed, 15 mile path length.)

3) The April 27, 2011 Hackleburg, Alabama tornado (71 killed, 25 mile path length.)

4) The April 27, 2011 Rainsville/Dekalb County, Alabama tornado (26 killed, 34 mile path length.)

5) The May 22, 2011 Joplin Missouri tornado (158 killed, 14 mile path length.)

6) The May 24, 2011 Binger-El Reno-Peidmont-Guthrie, Oklahoma tornado. (9 killed, 75 mile path length.)

Figure 3. EF-5 damage from the April 27, 2011 Neshoba tornado in Mississippi. The tornado was so powerful that it dug out the ground to a depth of two feet over an area 25 - 50 yards wide and several hundred yards long. Image credit: NWS.

A few other remarkable statistics on the tornado season of 2011, compiled from NOAA's official press release, the NOAA Extreme Weather 2011 page, and Wikipedia's excellent tornado pages:

- The tornado death toll of 552 in 2011 ties 1936 as the second deadliest year for tornadoes in U.S. history. Only 1925, with 794 fatalities, was deadlier. In 1936, violent tornadoes hit Tupelo Mississippi (216 killed), and Gainesville, Georgia (203 killed.) During the 1930s, the tornado death rate per million people was 60 - 70 times as great as in the year 2000 (Figure 4), implying that this year's tornadoes may have killed tens of thousands of people if we did not have our modern tornado modern warning system.


Figure 4. Death rate per million people per year in U.S., 1875-2011. Thin line with dots is raw rate, curved thick line is death rate, filtered by 3-point median and 5-point running mean filter, and straight solid lines are least squares fit to filtered death rate for 1875-1925 and 1925-2011. Dashed lines are estimates of 10th and 90th percentile death rates from 1925-2000. The death rate fell from 8 per million to .12 per million between 1940 and 2010. Image credit: A Brief History of Deaths from Tornadoes in the United States, Harold Brooks and Charles Doswell III, and updated by Harold Brooks in 2011.

- April 2011 had the most tornadoes of any month in U.S. history--753. The previous record was 542, set in May 2003. The previous busiest April was in 1974, with 267 tornadoes. The average number of tornadoes for the month of April during the past decade was 161, and the 30-year average for April tornadoes was 135.

- On April 27, 199 confirmed tornadoes touched down. This is the largest 1-day tornado total on record, beating the 148 recorded in 24 hours on April 3 - 4, 1974.

The year 2011 now has three of the top five tornado outbreaks on record (note, though, that reliable records for number of tornadoes only extend back in time to about the early 1990s):

- The April 25 - 28, 2011 Super tornado outbreak, with 343 tornadoes, is now the largest tornado outbreak in U.S. history. The previous record (3 days or less duration) was 148 tornadoes, set during the April 3 - 4, 1974 Super Outbreak.

- The May 22 - 27, 2011 tornado outbreak, with 180 confirmed tornadoes, ranks as the 4th largest 6-day or shorter tornado outbreak on record. A May 2003 6-day outbreak had 289 tornadoes, and a May 2004 6-day outbreak had 229 tornadoes.

- The April 14 - 16, 2011 tornado outbreak, with 177 confirmed tornadoes, ranks as the second largest tornado outbreak of three days or less duration on record, and 5th largest outbreak of six or fewer days duration.

- The May 22, 2011 Joplin, Missouri tornado killed 158 people and injured 1150, making it the deadliest U.S. tornado since 1947, and 7th deadliest in history. The $3 billion estimate of insured damage makes it the most expensive tornado in world history.

- Preliminary damage estimates from Munich Re insurance company put 2011's insured losses due to U.S. thunderstorms and tornadoes at $25 billion, more than double the previous record set in 2010.

- The year 2011 now ranks in 2nd place behind 1973 for greatest number of tornadoes greater than EF-0 strength (EF-1, EF-2, EF-3, EF-4 and EF-5 strength, Figure 5.)


Figure 5. Number of EF-1, EF-2, EF-3, EF-4 and EF-5 tornadoes from 1950 to 2011. The total shown for 2011 is preliminary and uses unofficial numbers through November 17, but 2011 now ranks in 2nd place behind 1973. There is not a decades-long increasing trend in the numbers of tornadoes stronger than EF-0, implying that climate change, as yet, is not having a noticeable impact on U.S. tornadoes. However, statistics of tornado frequency and intensity are highly uncertain. Major changes in the rating process occurred in the mid-1970s (when all tornadoes occurring prior to about 1975 were retrospectively rated), and again in 2001, when scientists began rating tornadoes lower because of engineering concerns and unintended consequences of National Weather Service policy changes. Also, beginning in 2007, NOAA switched from the F-scale to the EF-scale for rating tornado damage, causing additional problems with attempting to assess if tornadoes are changing over time. Data provided by Harold Brooks, NOAA/National Severe Storms Laboratory.

My husband and I were visiting my parents in Birmingham, Alabama. We decided to take a day trip to Tuscaloosa to see the damage from the April 27 tornado. It was a sight that I will never forget. Blocks and blocks of flattened houses and stores. This area has not been touched in 2 months. It was so moving that I started to cry thinking of all these poor people.

Hi all. I wonder how chilly it will get in the Keys. Not that we need to worry about snow falling, it's the iguanas. They tend to fall out of the trees when it gets cold. I don't want to be hit with one of them LOL.

Interesting perspective. And hope you are correct. I not only would not mind another year with a similar pattern for my own personal weather tastes, but also to really get a good chance to examine two full tropical weather seasons in the Atlantic Basin under the pattern.

I'll bookmark this link. Thanks Skyepony.
I just pray we won't have a season like 09 again...Gawwwwd no.I mean with hardly no tropical cyclones to track it does lower the risk of someone being hit but I love tracking tropical cyclones.And I do agree seeing two in the atlantic again at the same time should be fun :).

Tropical Cyclone Advisory #3
DEPRESSION TROPICALE 04-20112012
22:00 PM RET December 28 2011
===================================

At 18:00 PM UTC, Tropical Depression 04 (999 hPa) located at 12.0S 87.6E has 10 minute sustained winds of 30 knots with gusts of 45 knots. The depression is reported as moving west at 12 knots.

Dvorak Intensity: T2.5/2.5/S0.5/18 HRS

Near Gale Force Winds
=====================

90 NM radius from the center extending up to 150 NM in the southwestern semi-circle

Forecast and Intensity
=====================

12 HRS: 12.2S 85.5E - 35 knots (Tempête Tropicale Moderée)
24 HRS: 12.5S 83.2E - 40 knots (Tempête Tropicale Moderée)
48 HRS: 13.4S 79.2E - 50 knots (Forte Tempête Tropicale)
72 HRS: 14.9S 76.0E - 65 knots (CYCLONE Tropical)

Additional Information
=======================

The cloud pattern of the disturbance has little changed, the low level circulation is still on the eastern border of the cloud mass of deep convection. The low level flow pattern seems to be rather ill-defined. (CF SSMIS 37ghz at 14:00 PM UTC). Lower levels supply is currently good on the two faces of the system. However, system is still undergoing a moderate upper level east vertical wind shear.

The upper level constraint should progressively weaken within the next 36-48 hours. At 48 hours, an upper outflow channel should set up poleward. A second upper outflow should temporarily set up equatorward on Saturday and Sunday. Intensification should also remain moderate within the next 36 hours, but should heighten beyond. At the end of the forecast range (beginning of next week) upper level environmental conditions should become less favorable (strengthening of the upper level wind shear).

Available numerical weather prediction models are in good agreement for a west to southwestward track over the northern periphery of the subtropical high pressure and low and mid-troposphere.

The next tropical cyclone advisory from Mauritius Meteorological Services on Tropical Depression 04 will be issued at 0:30 AM UTC..

2010 was nice to the United States, but everywhere else, it was a horrible season.

* Alex devastated Mexico.

* Igor became the most destructive hurricane in Newfoundland history and the 3rd most destructive Canada hurricane in recorded history.

* Karl severely affected Mexico.

* Matthew caused severe flooding in Central America.

* Nicole soaked the Greater Antilles (Caribbean Islands) and East USA.

* Tomas produced torrential rains across Haiti.

Dr. Masters said the tornado season was the top US weather story of the year. What would you guys say was the top weather story of 2011 internationally?

Off hand, the most significant ones that come to my mind are the:
-On going Philippines disaster/recovery
-Japanese quake/tsunami
-Christchurch new zealand
-Southern drought/fires

(it's not weather, but i don't mind if you include earthquakes, ect...)

2010 actually caused more damage and killed more people than 2011. Now 2011 estimates are still preliminary and are only .041 billion less than 2010 at this point, but the point still rests. 2011 was pretty boring as far as hurricanes goes, but some of the TS's sure accomplished amazing feats. (forming in 40kts wind shear, strengthening in 40kts wind shear)

I'm going out on a limb and say that if you asked some folks two months from now what 2011 was known for, about 10% or less of them would say 'tornado.'

So 'forever' might be a bit of a stretch. I think more people would remember it as the year Kim Kardashian got divorced.

Darwin Tropical Cyclone Warning Center
Tropical Cyclone Advice #40
TROPICAL LOW, FORMER GRANT (04U)
5:00 AM CST December 29 2011
===================================

At 3:30 AM CST, Tropical Low, Former Grant (998 hPa) located at 14.4S 138.0E, or 180 km east southeast of Alyangula and 285 km north northwest of Mornington Island. The low is reported as moving east at 10 knots.

Dvorak Intensity: T1.0/1.0/S0.0/24 HRS

Ex-tropical cyclone Grant is located in the Gulf of Carpentaria and is expected to continue moving steadily east, and may redevelop into a tropical cyclone on Friday.

GALES are not expected in coastal areas of Queensland in the next 24 hours, however gales may develop later.

HEAVY RAIN potentially leading to flooding is expected to develop across the Peninsula and northern parts of the Gulf Country districts in Queensland during Thursday and Friday.

Tides will be HIGHER THAN NORMAL between Thursday Island and Mornington Island in Queensland. Large waves may produce MINOR FLOODING along the foreshore.

Cyclone Watches/Warnings
=======================

A Cyclone WATCH is current for a developing tropical low for coastal areas from Thursday Island to Gilbert River Mouth in Queensland.

Forecast and Intensity
=======================

12 HRS: 14.3S 139.3E - 25 knots (Tropical Low)
24 HRS: 14.1S 140.6E - 30 knots (Tropical Low)
48 HRS: 14.1S 143.4E - 30 knots (Tropical Low)
72 HRS: 14.2S 147.6E - 25 knots (Tropical Low)

Additional Information
=====================

Position poor primarily based on surface observations. System lies in a moderately sheared environment of 15-30 kt. LLCC exposed with deep convection displaced to the southeast. Due to the presence of a mid level trough, shear is expected to remain at least at moderate levels throughout the systems presence in the Gulf of Carpentaria. As such, the development rate of this system is expected to be slow with only a slight chance of redevelopment into a cyclone prior to crossing the coast of Cape York Peninsula.

The system is expected to move steadily to the east under the influence of the mid level trough and strong W steering in an increasing monsoon flow to the north.

The next tropical cyclone bulletin from Brisbane Tropical Cyclone Warning Center will be issued at 1:30 AM UTC..

Models are now just giving FL a glancing blow from the cold next week. What a bummer as I was hoping for a nice cold snap down here. The Euro has most of the cold moving toward the Mid Atlantic now basically mirroring the GFS. A quick shot of cold next week for C FL maybe 24hrs then gone.

We may have one more chance to get a freeze down here but if we don't soon then it looks as if we may have to wait until next year. Sorry folks but unfortunately the Euro is now following the GFS and keep the core of the cold away from FL. Now that's not to say we won't have a night or two next week in the mid to upper 30's but thats it.

We may have one more chance to get a freeze down but if we don't soon then it looks as if we may have to wait until next year. Sorry folks but unfortunately the Euro is now following the GFS and keep the core of the cold away from FL. Now that's not to say we won't have a night or two next week in the mid to upper 30's but thats it.
ECMWF may be coming more inline with the GFS, but from the 0z to the 12z run, the ECMWF has backed off a bit on the cold snap, while the GFS has intensified the cold snap from its 0z to 12z run.

I'm fine with it staying warm down here; I won't complain if there are no hard freezes. But it's been into the 30s as late as April here in Naples, so we still have another 12 or 13 weeks of cold weather possible (though it's never frozen past the end of February). I'm not ready to put away my jacket just yet... ;-)

While next weeks potential storm across the eastern US could bring very cool temperatures to the southern US, keep in mind it won't be bringing much precipitation and the precipitation it does bring will be mostly confined to the northern states. The reason for this is the strong surface high over the southwest and central us will prevent this low from diving significantly southward. This keeps the actual center of the low mostly over Canada, although it may briefly cross over into the US, which confines most of the precipitation to the north. Furthermore, this storm should not carry much moisture with it in the first place since it will lose most of its moisture in the mountains of the Pacific NW, it will be totally cut off from moisture in the Pacific due to the strong ridge building behind it, and, since it is so far north, it won't be able to pull much moisture out of the Gulf of Mexico.


Strong surface high on the 12z GFS at 63hrs preventing the low from diving down






12z GFS 60hr precipitation total at 144hrs

How wide was the Joplin Tornado? It looks like 1 1/2 to 2 miles wide.

Like Neapolitan said earlier that tornado season is just 2 months away give or take. Amazing! I'm willing to go out on a limb and say this going to be another devasting tornado year coming in 2012 as it looks like the same perameters are going to be in place again thanks to this nagging La-Nina.

Quoting Neapolitan:

There are a (luckily decreasing) number of people convinced against all logic that caring for our environment makes one a socialist ala Stalin. You know: imposing fuel consumption standards, say, or asking Big Energy to divert just a tiny portion of its hundreds of billions of dollars in annual highly destructive profit toward researching alternate forms of energy generation = door-smashing, jack-booted fascism. Or something like that.

Some folks would do themselves a favor by switching from the (un)fair and (anything but) balanced network. At least once in a while...


What a load.....

All though both the Tuscaloosa and Jopling tornadoes were both EF-5 I think the Joplin tornado had wind speeds well over 300 mph based on damage assements (stronger than that of the Tuscaloosa Tornado).
