Abstract
It is necessary to develop a new method to estimate characteristics of tornadoes from their photos and movies to evaluate strength and geometricalscale of tornadoes without using information of damages. Therefore, the flight of debris with some different Tachikawa number were investigated in tornado-like similar flow with some different scales that was generated by LES, in this study. As results of this study, it was clarified that the scale of tornado-like flow controls the flight of debris and debris were blown out by centrifugal force strengthen by smaller radius of their trajectories at the same relative points. This result indicates that the geometrical scale of tornadoes should not be a representative length for the flight of debris. Tachikawa number also controls the debris flight. However, even if Tachikawa number was kept constant, trajectories of debris were changed by the scale of tornado-like flow.
