We Fucked the Jetstream...BIG TIME.....

60. Probably one of the most flawed stats in weather...

Tornadoes have to be seen and/or damage something to be counted.

With Storm Chasers, radar signatures, and increasing population density, we might, MIGHT be getting better numbers..soon...

AMY GOODMAN: Jeff, what is the connection? Is there a connection between this tornado and global warming?

JEFF MASTERS: That’s a tough call. I mean, it’s an important question. And we really have a huge area of unknowns here to try and answer that question. The big problem is the tornado database isn’t very good. It only goes back about 60 years. And we don’t measure tornadoes directly. They have to run over a building before we know how strong they are. So we’ve got a lousy database. And our computer models to study tornadoes aren’t very good yet. We don’t understand what makes them tick very well. So, even with our highest-quality, finest research models, can’t tell you what a tornado is going to do and how it’s going to form, we can’t expect our climate models to do that sort of math, either, because they’re a lot courser. They can’t look at the fine details very well. So, a lot of uncertainty about how climate change might affect tornadoes.

I might add that over the past 12 months, we’ve seen the record lowest number of tornadoes in U.S. history, at least the EF1 and stronger tornadoes. But back in 2011, we saw the record highest 12-month total of tornadoes. So, we’ve just been getting kind of weather whiplash with our tornado seasons. I mean, going from the extreme highest to the extreme lowest, that’s really tough to, you know, say what is the trend going to be. Well, it might be one or the other. And at this point, I can’t identify what climate change is likely to do, which of those type of years we’re more likely to get.

Which is why my OP says "Weather Weirding on Steroids."

But, TBH, I don't remember huge tornadoes hitting the same places over and over like we're seeing. I find that, disturbing.
