Cloud photogrammetry and single-Doppler radar analysis of the 5 June 2009 La Grange, WY tornado during VORTEX 2
Many digital images of the wall cloud and tornado have been photogrammetrically analyzed. This poster will present results where, for the first time, photogrammetrically analyzed photos of the tornado are combined with single-Doppler DOW data. An important result of this analysis is the source of high-reflectivity rings that often surrounds the tornado. While previous research has speculated that debris is responsible for the high-reflectivity rings, it will be shown that a high-reflectivity ring surrounding the La Grange tornado is due primarily to precipitation wrapping around the circulation. Results showing the concurrent evolution of the tornado funnel and parent mesocyclone observed in the radar data will also be presented.
