Twisters are twirling away from Tornado Alley.

From 1979 to 2017, annual tornado frequency slightly decreased over the region, which stretches across the central and southern Great Plains of the United States, a study finds. Conversely, a higher number of storms touched down in areas east of the Mississippi River over the same period, researchers report October 17 in npj Climate and Atmospheric Science.

"The great Tornado Alley is still No. 1 in terms of [overall] frequency," says coauthor Victor Gensini, an applied climatologist at Northern Illinois University in DeKalb. But more tornadoes in communities ill-prepared to face the relatively unfamiliar storms, such as in the southeastern United States, could mean more infrastructure damage and loss of life.

The Deep South should get to work on its tornado shelters?

    The Mississippi delta maybe but most of the South has hills sufficient to make tornadoes not too much of an issue.

      Florida - Hills? I don't think so.

      The tornadoes that ripped through northwest Georgia / northeast Alabama ~5-10 years back didn't seem to care too much about the hills they shaved clean.

      Hills neither help nor hinder tornadoes. Tornadoes don't usually jump over valleys (the set of complex conditions that support tornadoes can vary), but rather roll down them and up the other side. And hills don't stop tornadoes from forming, though elevation can matter under some circumstances (such as those places on earth that are close to, or above, the storm system altitude).

      I'm in very hilly southern Indiana. In the early 70s a F5 started in kentucky, rolled down the several hundred foot drop into the ohio river, crossed it, went up the other side and kept going. We have tornadoes here constantly (at least a dozen a year within 30mi of me). They aren't uncommon at all in hilly areas.

    The Deep South should get to work on electing politicians who will do something about climate change.

      Do you have a reason for that belief? Evidence maybe?

        Yes, its proven that taxes are statistically significantly inversely correlated with climate change.

      Maybe.

      FWIW, I believe in climate change already, but I'm not convinced that this is related. It *could* be, but I'd need some grounds for the attribution, e.g. "tornadoes are normally driven west by the more active jet stream", but that explanation looks really fallacious for this event.

          Did they, eh? So this is a prediction then?

          Recent increases in computational efficiency have led several studies to explicitly depict severe convective storms in convective permitting regional climate model configurations to evade the previously discussed environmental caveats.20,21,22,23,24,25 These dynamical downscaling approaches (sometimes referred to as model telescoping) have proven reliable for the replication of spatial frequency and temporal timing of the annual peak of boreal severe weather activity. Potential changes in characteristics of late 21st century severe weather activity have also been posited by these methods. However, due to the resource intensive nature of these approaches, long model-derived climatologies are often unfeasible and it is not yet clear if the explanatory capability is significantly better than environments to justify the resources necessary to conduct such simulations.

          A glaring warning sign of anti-scientific bias is false confidence.

            Climate scientists use ensembles of models that predict every possible outcome of climate change. Each model makes assumptions that contradict the other models. Then once something happens they go back and cherry pick the ones that "predicted" the right thing. Its like string theory or dark matter theory, once we start heading towards the next mini-ice age they will say they predicted that too.
