Below is an X Band Doppler/Dual Polarimetric Radar image of the El Reno tornado. You can actually see the vortex! Reflectivity is upper right and Doppler winds are lower left. Correlation Coefficient showing large amount of debris is bottom right. This image is from an experimental Doppler/ Dual Polarimetric radar at the Univ. of Oklahoma developed by Dr. Howie Bluestein (One of my professors many years ago!).
