This study is intended to recognize the importance of cold-wind, which is one\nof the solutions to improve urban amenity, and verify the model that can\nanalyze creation and flow of cold-wind. For this reason, KLAM_21 Model,\nwhich was developed by the Germanâ??s Meteorological Service, was selected\nand used for assessment of cold-wind creation and flow. As a result, the\nfollowings have been drawn through comparison with measured data and\nsimulated data in the study area; for a mountain area, the simulation result of\nvelocity and direction of wind has been indicated as similar as those in measured\ndata. For a stream area in the city, only wind direction from simulation\nhas been consistent with measured data whereas wind velocity showed a large\ndifference between measurement and simulation. Finally, for the downtown\narea, wind velocity has shown a lot of differences between simulation result\nand measured data. Wind direction has also shown a large difference until\nmidnight. But after midnight, model data have become similar as measured\ndata. According to the verification of this study, the model used in this study\nfor using urban-amenity improvement through assessment of creation and\nflow of cold wind is suitable to analyze the direction of cold wind that is generated\nin the periphery of the city and the overall flow within the existing urban\narea. But the results of wind velocity have shown the uppermost limit of\nthe modeling in the simulation. That is, it could not reflect the site characteristics\nsufficiently. Therefore, if parameters considering the specific regional\ncharacteristics are sufficiently reflected, the result of simulations for reliability\ncan be substantially improved.
