Research takes you places you’ve never been. In my case that’s Oklahoma (watching the musical doesn’t count).
Here’s a chart I pulled together, which tracks average tornado records in the period 1950 to 2013. For smoothing purposes, I took an 11 year average, charting against the middle year. No reason for 11 years other than similarity to the sunspot cycle.
I couldn’t resist the urge to model this.
I still haven’t been… and yeah, this ties in with Alibi, top of my to-write list.
