     in the present study, assessment of wind environment within the pedestrian level domains of highly populated areas is carried out. three typical models of a dense urban area are considered and numerically simulated in order to examine the effects of the geometry of such models on wind flow characteristics within the pedestrian domain of a street canyon located within this area. the calculated flow fields are employed to estimate the exceedance probabilities within the study domain using a new approach: average wind kinetic energy. the study is applied to tokyo, japan; based on its mean wind velocity data. the results demonstrate that the exceedance probability analysis of the pedestrian wind environment could be a valuable tool for assessing urban areas. also, the calculated probabilities demonstrate substantial dependence on both the geometry of building arrays and the wind conditions of the considered domain.
