Comparisons of fine-scale radar observations and in situ tornado pod observations of low level tornadic winds

A DOW radar, several Tornado Pods, and the TIV manned tornado penetration vehicle obtained data in two tornadoes during the spring of 2008. The core flow and near core flow regions of two tornadoes crossing in and near the towns of Stuttgart, AR and Glen Elder, KS were observed. Preliminary results comparing low level DOW winds and 1 and 3.5 m in situ winds suggest that strong asymmetries may exist in the lowest levels of the tornado boundary layer with strong inflows in some zones and nearly tangential flow in others. Preliminary Rapid-Scan DOW observations and in situ observations of tornadoes obtained in the 2009 field phase of VORTEX2 will be presented.
