MM5-CAMx를 이용한 대기오염물질의 재순환현상 모델링 = 2004년 6월 수도권 오존오염 사례연구

다국어 초록 (Multilingual Abstract)

Recent evidence has demonstrated that the pollutant recirculation can play an important role in leading to high ozone(O₃) concentrations. In this study, the MM5-CAMx air quality modeling system was applied to simulate the pollutant recirculation and identify the transport of pollution during the high O₃ event (the maximum O₃ of 195 ppb) observed in the Greater Seoul Area (GSA) on 1~4 June in 2004. The results showed a weak northeasterly synoptic wind during the night and early morning moved the air parcels containing the locally emitted urban pollution to the coast, which contributed to enhance O₃ formation in the southwest part of the GSA. As the sea breeze developed and started to penetrate inland in the late afternoon, the rapid build-up of O₃3 concentration was found in the southwest coastal area due to the recirculation of the polluted air loaded with high level O₃. The simulated backward trajectories and observations at coastal sites confirmed the recirculation of pollutant with the late sea breeze is the dominant factor affecting the occurrence of high O₃ concentrations in the southwestern GSA.
