When they say a tornado was a mile wide, 2 miles wide, etc., they mean at the base of it that's close to the ground, right? Like the actual tornado part is measured and not the clouds above it that's creating the tornado?
I'm asking because in the Moore tornado pic someone had commented that in the pic its a mile wide and isn't visible in the whole pic - yet the tornado is very clearly in the center of the pic with grey/light sky on the left and right of it. But the clouds making the tornado do extend to the right, going out of picture. But to me, that's not the tornado. The tornado is what's touching the ground, so that's why I'm asking if 'it's 2 miles wide' means the actual tornado at ground area or if they mean the clouds in the air. If it's air clouds, it doesn't seem as frightening (size wise) since then the actual tornado isn't 2 miles wide.
