Through the ground-based Velocity Track Display (GBVTD) technique, a single Doppler radar can be used retrieve the three-dimensional kinematic structure of a tornado. The GBVTD technique and GBVTD-simplex center-finding algorithm first had to be adapted from use on hurricanes to use on tornadoes. This technique was then utilized to retrieve the two-dimensional circulation of the Goshen County, Wyoming tornado from data collected by two individual Doppler radars on Wheels (DOWs) during the VORTEX2 field campaign. The GBVTD-retrieved structure was analyzed throughout the tornado's lifecycle and was compared to preliminary dual-Doppler radar analyses.
The GBVTD technique was shown to resolve large-scale features of the storm circulation, as well as features of the tornado, and it compared favorably to the preliminary dual-Doppler analyses. The GBVTD technique was further shown to be adaptable to tornadoes and promising as a three-dimensional tornado analysis tool, capable of improving the current understanding of tornadoes and decreasing their potential impacts on society.
