 And really, I think what we're doing a lot of is observing more tornadoes than we ever have before. So I think part of this is that part of the country is active one year, then another part of the country is more active another year. I think overall some of the work has shown that there's been an increase in parts of the south-central United States. But at the same time, I'm wondering about if we studied it from different angles, what we would see, like storms that produce tornadoes.
