How modern Tornado detection via Radar works. "Radar Confirmation" of Tornadoes vs storm spotting and ground truth. I break down how Doppler and Correlation Coefficient is used to find Tornado Debris Signatures and Tornadic Vortex Signatures. And I compare this to ground truth scenarios on the March 25th Alabama Tornado outbreak, as well as a Tornado producing storm in Childress, Texas on March 12th. Yes, March 12, not May 12, my bad.
