This study was performed to determine the relationship between air pollutants and
meteorological factors such as wind direction, wind speed, etc. in Seoul. The
measurement data were collected in background and border monitoring networks in
Seoul, from December 2014 to November 2015. The wind rose was generated for each
season using these data. The data were analyzed using the 2-Way ANOVA and multiple
regression analysis. Gwanaksan had the highest wind speed across the four seasons,
while Namsan had the lowest. Segok had the highest concentration of all pollutants
except O3, while Bukhansan had the lowest. In Gwanaksan, there was no difference in
concentration due to the interaction between wind direction and wind speed during
winter, while in Namsan, there was no difference during the rest of the seasons, except
winter. NO2 and CO showed a negative correlation with wind speed, while O3 showed
a positive correlation with wind speed and pollutant concentration. PM10 and PM2.5
showed a weak correlation with wind speed, except during summer, when they showed
a negative correlation. Gungdong had the lowest adjusted Ra2 value among all the
pollutants except during winter, while Segok had a higher adjusted Ra2 value for
gaseous pollutants.
