Abstract

Global warming due to the climate change causes environmental problems such as urban heat island (UHI), air pollutant deposition, urban heavy rainfall, etc. Urban stream plays an important role on mitigating UHI as open space as well as an ecological corridor in urban area. In order to investigate the wind characteristics of urban stream in the case of Yangjae Stream at Daechi-dong, Gangnam-gu in Seoul, the wind direction and wind speed data were observed and analyzed using a propellor type RM-Young wind monitor. The results show that the prevailing wind direction was southwest. However, easterly wind is the prevailing one between 8:00 and 12:00. Strong wind whose Beaufort scale is four or more blew frequently from 12:00 to 18:00. In terms of seasonal frequency, the spring shows the highest frequency, then winter was the next.
