Discussions with James LaDue of the National Weather Service’s Warning Decision Training Branch led to the realization that we needed to investigate the influence of various tornado vortex models and reflectivity profiles on the tornadic vortex signature. We appreciate comments on the manuscript by Travis Smith and the anonymous reviewers.
