Abstract

The street canyon forms the geometric unit of the built environment. The geometry makes up urban canyons and it influences the urban climate. In order to investigate the wind characteristics of urban street canyon at Dogok-dong, Gangnam-gu in Seoul, the wind direction and wind speed data were observed and analyzed by using 2-D ultra sonic and propeller wind monitor from May 5, 2010 to May 4, 2011. The results show that the prevailing wind direction was west at Station A(Military Mutual Aid Association Building), southwest at Station B(Sookmyung Girls' High School) and the wind speed of Station B was higher than Station A. There were diurnal differences about prevailing wind direction between two stations : it was westerly wind at Station A for a whole day, but at Station B only from 22 : 00 to 04 : 00. However, Station B is different from Station A at other time. At Station B, it was easterly wind from 04 : 00 to 12 : 00, southwesterly wind from 12 : 00 to 22 : 00. In terms of seasonal(except winter) frequency, the spring shows the highest frequency and fall was the next.
