This study was carried out to research the influence of climatic conditions including wind direction, wind speed on air pollution in Seoul. The data were obtained from the 4 sites of air pollution monitoring stations in Seoul from '95 to '96, and analyzed statistically by SAS program. The results were as follows 1. The prevailing wind directions by season in each site were as follows Nangajwa-dong were showed SE in spring, fall, winter and WNW in summer. Ssangmun-dong were showed NW in spring, fall, winter and NNE in summer. Kuro-dong were showed SW in spring, summer, ENE in fall and NW in winter. Bangi-dong were showed WNW in four seeasons. 2. The concentrations of 5 kinds(SO $_2$ , Dust, NO $_2$ , CO, THC) of air pollutants were relatively low in west wind. In case of O $_3$ was opposite. 3. The concentrations of 5 kinds of air pollutants were increase with decreasing wind speeds. 4. The washing effects of air pollution by rain were significant. The concentrations of 5 kinds of air pollutants were high when the humidity were 61-80%, and low as it were 0-20%. In case of O $_3$ was opposite. 5. All of air pollutants concentrations but O $_3$ were high when the UV intensity level and temperature within the range of above zero were low level. |
