2011: Year of the Tornado

By: Dr. Jeff Masters , 7:25 PM GMT on December 27, 2011

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.



Figure 1. A truly frightening radar image: multiple hook echoes from at least ten supercell thunderstorms cover Mississippi, Alabama, and Tennessee during the height of the April 27, 2011 Super Outbreak. A multi-hour animation is available here.

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.

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.

Agreed. I like to avoid conflict. When I've been in conflict before it was generally in defense of people here. I have defended Dr. M and other prominent posters many times and I still have a lot of respect for many people. But why would someone change the content of private emails without the sender's knowledge? That is creepy and unacceptable. And that applies regardless of where you want to spend your time. I spent a lot of hours here, I've contributed to charities, and I've admired a lot of people, a number of whom are still here. I still like to read and evaluate data on GW...I think Dr. M has a right to use his own blog as a forum for that. What really bothers me is the alteration of private emails without even notifying the sender. That crosses the line in my book, even if it's legal.

Irene was 'just a 1' and it washed out a road conecting the outer banks to the rest of them islands and the mainland(i think) with 85 mph windspeeds. i seriously wish to have a scale created with storm surge a factor!
I'm thinking maybe a SSHS with a Surge Factor added. "Hurricane Xero is expected to impact US coastal areas as a category three with moderate surge factor..." I don't think a simple modification of SSHS will work; we've got multiple examples of hurricanes with relatively low winds but high storm surge, and I'm sure the opposite is possible as well.

It's not "an attempt to restrict a member's ability to share information"; it's a hugely popular website preventing unpaid hyperlinks to a very small website, as is its right. Allowing free links would be unfair to those many advertisers here who pay to have links to their sites.

Quoting FLWeatherFreak91:
Wow. Wunderground is predicting a low of 25 degrees for northern Hillsborough Co, Fl, while the NWS is forecasting a significantly more mild 37. I imagine the Wunderground forecast is based solely on model guidance and the NWS is using human forecasts. We'll see if it gets that cold.


Bestcast is more than model guidance..it uses some info for the PWS it is forecasting for. So if that info is not accurate for which ever PWS you watch I'd go with NWS. Bestcast is in it's first year too. Yesterday morning's Bestcast & NWS offical forecast..both were way colder & adjusted up by day's end. I've gotten used to it's ways for my PWS & use it like another tool in coming up with my own forecast..

It's Dr. M's blog. You agreed to the terms and conditions when you sign up. The terms and conditions actually aren't all that much different from other popular websites (if you actually care to read the terms). He can post what he wants, when he wants.

Climate change and weather go hand in hand. A rather large body of scientific evidence and research show that this is so. Dr. M posts references to this research when blogging about the influences climate has on weather, and how our currently changing climate is affecting weather. If you want climate discussions based on belief and "truthiness" instead of scientific fact, go to Steven McIntyre's or Anthony Watts's sites.

Now, if you find scientific discussions on such matters not to be your cup of tea, don't like having your beliefs challenged, or if you suddenly bothered to read the terms and conditions and find them not to your liking, then by all means go somewhere else. But You were not misled. You were not duped. This is Dr. M's house. You either play by his rules or you get shown the door.


You are correct. Any member who signed up agreed to the terms and conditions. I believe that "linking" to a commercial weather site is prohibited. I accept that this is the rule; however, if I mention that I saw a posting of value on the bunker site in a WU mail to another WU member, this is not linking for promotional purposes. Yet, my email is changed. Not only is it changed on the recipient's end, it is also changed in my "sent" box, as though I actually typed the "changed" words. This practice, I believe, would be beyond questionable.

Also, of note.....the rule regarding linking to commercial sites is not applied to any other websites that I tested, except for .com ( this is the Bunker site I have typed, in case it is changed). I tested the following in my own WU mail account. Within the account it changes the Bunker site to wunderground.com....here is this blog comment, I believe it will change it to just ".com"



wunderground.com
.com----->this is the Bunker website
weather.com
accuweather.com
thextremeweather.com


These were just a few that I tested, but it was enough to determine that this is not a "rule" that is being enforced, but IS an attempt to restrict a member's ability to share information.

It in fact would be absurd not to be discussing relevant scientific research on the subject. jmo...

Salt Lake City:

We're on track to have the driest December on record and ski resorts are way below normal for snowfall. Plus tomorrow's high is forecasted to be near a record high.


And we are 600 miles south-southeast from you in Albuquerque and we have had almost record snowfalls at times and one of the colder Decembers in a long time. Go figure. I even heard Sandia Peak Ski area outside of Albuquerque has a 68 inch base. I cannot remember that happening in December and I have been here 34 years. Last year they hardly got the ski area open all season.

Wow. Wunderground is predicting a low of 25 degrees for northern Hillsborough Co, Fl, while the NWS is forecasting a significantly more mild 37. I imagine the Wunderground forecast is based solely on model guidance and the NWS is using human forecasts. We'll see if it gets that cold.

It's 47 degrees here in Central Illinois and that's only at 7 am. , it also appears that I now am going to have to mow my yard again. The grass has made a comeback this winter. I have never seen that happen before.


45 here in Marlow, OK at 7:30 am. High temp supposed to reach into 70s tomorrow. I can't help thinking Father Sky wants to create some balance for Mother Earth and her flora and fauna after the past two icy-bad, blizzardy winters ('specially 09-10), the EF5 and two 190 mph F4s on May 24, and the exceptionally droughtful conditions this past summer. Grass was brown and crunched all summer and has been green and happy since early Sept. Birds around, too, that maybe would be elsewhere this time of year if not for the warmth.

Illinois has also had more than its share of extreme weather of late. Winter can wait a while.

Going to be really cold across Florida next week, and Alaska as well. But the western 2/3 of the nation is going to be above normal--and it'll be absolutely sweltering (relatively speaking) in the upper Great Plains (look at that deep red across the northern tier:

Uh-oh
