Very cool chart. Interesting how much energy is in a large lightning bolt, and how relatively little in an average tornado, as most comparisons I’ve seen show an average thunderstorm exceeding the Hiroshima blast. Then again, an average thunderstorm might last an hour, and an “average” tornado is, I suppose, maybe an F1 that lasts 5 minutes...? So, duration is surely at play in these figures.
For comparison, a 1 mile dia. asteroid whacking us would release roughly the equivalent of 2.26E5 Megatons of TNT, or, if I’ve punched my calculator correctly, 452 quadrillion lbs. of TNT.
