In order to improve the prediction of the regional air quality modeling in the Seoul metropolitan area, a sensitivity analysis using two PBL and microphysics (MP) options of the WRF model was performed during four seasons. The results from four sets of the simulation experiments (EXPs) showed that m...

| 수도권의 대기 오염 상태는 어떠한가? | 지난 수십 년간 우리나라는 지속적인 도시화와 경제성장이 있었고 이로 인해 대기질 악화현상이 중요한 환경문제가 되었다. 특히, 수도권은 국내 다른 지역과 비교해 대기오염 현상이 심각하며(MOE, 2005), 선진국 주요 대도시와 비교에서도 대기질이 좋지 못하다(PM10은 1.8 3.5배, NO2는 1.2 1.7배 높은 수준; GRI, 2011). 최근에는 중국에서 배출된 대기오염물질의 장거리이동 역시 수도권 대기질 악화에 기여하고 있다(Ha and Moon, 2013; Oh et al. | |
| 대기질 악화현상의 원인은 무엇인가? | 지난 수십 년간 우리나라는 지속적인 도시화와 경제성장이 있었고 이로 인해 대기질 악화현상이 중요한 환경문제가 되었다. 특히, 수도권은 국내 다른 지역과 비교해 대기오염 현상이 심각하며(MOE, 2005), 선진국 주요 대도시와 비교에서도 대기질이 좋지 못하다(PM10은 1. | |
| 기상입력자료를 얻기위한 기상모델의 수행에 큰 관여를 하는 것은 무엇인가? | 기상입력자료는 기상모델(Weather Research Forecast, WRF 등) 수행을 통해 얻어지며 지표피복 및 지형자료, 초기·경계조건의 정확성, 공간해상도, 수행 옵션 등의 적절한 선택에 따라 그 정확도가 달라진다. 특히 기상모델의 수행에 있어 대기경계층(planetary boundary layer, PBL) 및 미세물리(microphysics, MP) 과정의 옵션 선택은 대기하층의 기온, 바람, 수증기와 구름복사효과를 변화시키는 중요한 부분으로(Cheng et al., 2013; González et al. |
