This paper reports the numerical experimental results of the flying path of spherical wind-borne debris from a 50m height, focusing on the effects of several roughness conditions. We prepared the numerical strong wind fields including the u and w components of wind speeds reflecting the turbulent structure under each roughness condition. The flying paths of debris in these wind fields were estimated many times and the results were statistically analyzed. As a result, it was found that under the lower roughness situation the debris flied farther and its dispersion became bigger. The w component of wind speed might make the flight duration of debris longer, but did not affect its dispersion so much.
