초록
Wind velocity must be maintained yearly because of the change of roughness of upward of the wind direction. Because of this, it is necessary to analyze ground roughness for wind velocity standardization. Therefore, this research will investigate the comparison and connection between ground roughness and G.F.(Gust Factor) as a result of urbanization and changing terrain. Following is a summary of the study. For the wind standardization, it is necessary to know the ground roughness at the point of measurement, however, most of the meteorological stations do not have that data. Generally, G.F. has high relation with ground roughness. In this respect, this research is aimed to determine the Daily Gust Factor of the meteorological stations on a yearly basis and to compare the latest ground roughness with picture and geographical map analysis, and on the basis of these results, to obtain the G.F. and and ground roughness of each meteorological station.
