Statistical analysis of tornado-induced damages in Japan have been conducted and compared with Fujita Tornado Damage Scale for determining the parameters of tornado model. Based on determined parameters, tornados were scaled down and reproduced by tornado generator facilities for comparison with observed statistics. Then, by utilizing multiple-fan wind tunnel, non-stationary flow of tornado was simulated and wind pressure measurement of prism models under such flow was conducted to evaluate the distributions of wind pressure coefficients due to overshoot phenomenon observed in tornado-like wind velocities.
