FLYING CHARACTERISTICS OF WIND-BORNE DEBRIS BY TWO ONE-CELL TORNADIC MODELS

Flying characteristics of wind-borne debris were investigated using two one-cell tornadic models. Wind-borne debris was assumed to be released at 961 points at each of 21 different heights. Fluctuating wind speed was considered and the fluctuating components were generated from the power spectral density with a constant power. From the analyses, it was found that the effect of tornadic models on flying characteristics was large. But, the effect of fluctuating wind speed was found to be small. It was also found that many release points from various heights need to be examined.
