Are you aware that tornados are defined as funnel clouds that actually reach
the ground? Doppler Radar helps us detect cloud rotation for advance
warning, but they do not help us determine whether a touchdown has actually
occurred. This is done by a site visit to ascertain the damage on the
ground. (Don't you watch the Weather Channel?)
So, no, it is not explainable by Doppler radar. If it were, I would expect
the graph to be relatively flat with steps at the point that radar and later
Doppler radar were deployed. This is not reflected in the historical data,
which instead shows a definite incline before and after Doppler radar.
