[en] This investigation examines, from the aerodynamic viewpoint, the necessary conditions required to lift relatively large, heavy objects from ground level into a tornado flow field. The specific objects of interest are a Schedule 40,12' diameter steel pipe and a 4,000 pound family sedan-type automobile. Analyses consider, in addition to the aerodynamic characteristics of the objects of concern, the surface boundary layer at or very near the tornado funnel, aerodynamic ground effects, and possible injection modes
