inmiddels prima verwoord door Jeff Duda op Stormtrack:

My own opinion of this: I'm disappointed in the change. I think radar estimated winds should be allowed to modify tornado ratings. My reasoning: what's the point of the (Enhanced)-Fujita scale? Wasn't the original purpose of it to get an estimate of the wind speeds in tornadoes? Since its its inception up to the last few years, no reliable observations of wind speeds near the ground existed in tornadoes, so the only way to estimate the winds was based on damage. I think that led people to thinking the (E)F-scale was only ever meant to rate damage. If that were the case, I see no reason to ever attach wind speeds to the final damage rating. Since wind speed estimates are indeed attached to ratings, I think it's because of the attempt to estimate wind speeds in tornadoes. If we have tools now that are capable of providing more reliable estimates, why should we not use them? If your argument is something to the likes of the consistency of Storm Data or the F-scale in general, you don't even know how many tornadoes occurred but were never reported in the era since the (E)F-scale was first used and how many tornadoes pre-1960s-ish were rated months or years after the fact using damage photos available. Tornado damage was not particularly well documented to have done a thorough evaluation of damage in that time. Even today, NWS offices still use different policies to survey and document tornadoes. So there really isn't any consistency.


Vet is mijn nadruk.
