CNN In recent years, scientists have noticed an increased frequency of tornadoes in the Southeast, carving a path of lost property and lives. Is 'Tornado Alley' shifting east? - Yahoo News Why do scientists believe 'tornado alley' is shifting? The federally funded scientists need to ask whether this is the first time that tornadic activity has shifted its . "There are more things, more people, more of us and more of our possessions in the mid-South," said Ashely. The worst place to be is somewhere fully exposed, where flying debris can hit and kill you, or in a manufactured or mobile home. Is Tornado Alley Shifting East? - The Weather Station Experts Tornado Alley is shifting eastward into the Mid-South. "Northeast Texas, eastern Oklahoma, the Arkansas River Valley, the mid-South, these areas are expected to see a near doubling of storms that produce tornadoes," said Walker Scott Ashley, professor of meteorology at Northern Illinois University. For example, as the graphic below shows, Kansas and Oklahoma still experienced a significantly higher number of tornadoes than elsewhere in the country from 2002-2021, but Mississippi, Alabama, and Louisiana are basically on the same level. All rights reserved. 2023 Scientific American, a Division of Springer Nature America, Inc. More violent and widespread tornado activity -- like the line of severe storms in recent days that killed dozens of people -- is expected in the future as global warming persists, experts told ABC News. Wenn Sie Ihre Auswahl anpassen mchten, klicken Sie auf Datenschutzeinstellungen verwalten. Our recommendation? Tornado activity in early 2023 epitomized the trend. Houser said the mega-drought that's been plaguing the South Central Plains for the last 23 years may be to blame. The mid-South is at a 25% greater risk of tornado threats, an expert said. Dr. Vittorio Gensini from Northern Illinois University and Dr. Harold Brooks from the National severe Storms Laboratory in Norman, Oklahoma have tracked the number of tornado reports between 1979 and 2017 to find that over the past four decades tornado activity has decreased in parts of Texas, Oklahoma, Colorado, Nebraska and Kansas. While we can't use that to predict individual storms, it might work as an early-warning system to indicate whether we expect an active tornado season or a quiet one. Example video title will go here for this video. While meteorologists quickly learned of Tornado Alleys severe weather, the term was first used in 1952. Thats the easiest way to keep yourself safe and is far more dependable than the often incorrect weather app. A spate of devastating tornadoes that have recently ripped through parts of the eastern and southern US states could portend the sort of damage that will become more commonplace due to changes wrought by global heating, scientists have warned. Ramping up first in the Deep South in March, tornado season peaks in Tornado Alley in May and June. This is the second official Tornado Alley, known as Dixie Alley. "These houses are just not built to withstand even minimally strong tornadic winds," Ashley said. Another factor driving the cause of increased impacts from tornadoes is the "expanding bullseye effect," in which rural communities between the large cities in the south -- Atlanta, Charlotte, Nashville -- have rapidly increased in population over the past 50 years, Ashley said. 2023 CNBC LLC. Climate change may extend the typical tornado season as well. While predicting specific weather systems is limited to about a week's lead time, models are pretty good at forecasting SST in the Gulf of Mexico about three months out. "The truth is that if you prepare and do the right thing, your chances survivability is almost 100%," Ashley said. Our Top 10 lists count down the warmest, wettest, and snowiest places around, and explain what drives the weather in these locales. A week later storms in the new tornado alley killed more than 30 people, and another group on April 4 damaged more than 80 structures in Bollinger County, Missouri. Previous research has shown that over recent decades there has been a stagnation, or even slight drop, in the number of tornadoes in their traditional home range of the Great Plains, but an uptick in states further east, such as Tennessee, Mississippi, Alabama, Illinois and Indiana. Keeping up on Alerts and information will save your lives. As a result, reinsurers are raising prices, limiting coverage and even exiting some markets to improve returns. Still, the factors driving tornadoes are complex and the link to climate change is far less understood than it is for phenomena such as heatwaves, for which scientists are now able to pinpoint an exact global heating influence for individual events. Tornado Alley is known as being the most active place for large and dangerous tornadoes in the central United States, but that could be changing. But it's all happening, Dickson said, at a time when insurance dollars are diminishing. This may be responsible for part of the increase in tornadoes annually. This new Tornado Alley is much larger. Since 1979, the amount of favorable tornado days has declined for Texas and part of the original Tornado Alley. On the other hand, La Nia brings a more wavy and northward shifted jet stream, which might be expected to enhance severe weather activity in the south and southeast. American Meteorological Society expects that with the changing climate tornado season will escalate outside of the traditional peak season, which is March through May, according to a study published earlier this year. They also point towards an increase in variability by the end of the 21st century in portions of the Midwest and Southeast, suggesting that the trends herein may indeed be due to anthropogenic forcing given the accumulating literature examining tornado and severe weather frequency and variability. "The odds of something being hit by one of these events is going up substantially," Ashley said. Drought (including lack of fluid water in winter) will drive them into dormancy. Tornadoes need four ingredients to form, explained Ashley: moisture, instability (which provides the energy necessary for the storms), wind shear and lift. Widespread droughts to the west and southwest appear to have shifted this pattern further east. With more moisture, atmospheric instability -- the "gasoline" for storms -- and wind shear, the unique dynamical force that allows the twister to become organized -- strong storms, hail and tornadoes are more likely, Ashley said. Some of this is due to La Nina, which generally brings warmer than normal winter temperatures to the Southern U.S. These two are recognized by the National Weather Service and the Storm Prediction Center.

Two severely damaged homes are seen in a neighborhood in the aftermath of a tornado in Sullivan, Indiana, April 2, 2023. As one research team concluded, at this point studies into what climate change will mean for the intensity, number, and distribution of tornadoes largely serve to highlight the need for more studies. Overall, the research indicates that an environment supportive of the formation of tornadoes is expanding in the southeast, the experts said. The geographic location with the most frequent tornado activity tends to change year over year, Houser told ABC News. New research suggests that Tornado Alley as we know it is moving east. A new study says the tornado threat zone may be spreading eastward, to the densely populated . However, the recent change could be due to changes in the climate.
