Since 1970s, the rapid urbanization by Korean economic development causes change of surface roughness and global warming is affecting a rise in typhoons. therefore it is required to improve the basic wind speed map of Korean Building Code 2009 reasonably by applying the recent meterological data. this study shows building basic wind speed map by investigating regional meterological data(1973~2012) and estimating the design wind speed for Daegu-Gyeongbuk Region. thirteen cities is selected in this study for the past thirty years and the wind speed is calibrated by considering effective height of anemometer in hilly areas. we estimated the wind speeds for 100’s years return period including annual maximum, High temperature seasons, Low temperature seasons.
