국지풍 모델과 2차 모멘트법을 이용한 대기오염 물질의 이류확산 수치모의 = Numerical simulation of Advection/Diffusion of Air Pollutants using the Local Wind Model and Second Mement Method

다국어 초록 (Multilingual Abstract)

The two-stage numerical model was used to study the relation bitween three-dimensional local wind model,adviction/diffusion model of second moment method in south-eastern coastal area for Korean peninsula.The first stage is three dimensional time-dependent local wind model which gives the wind field and vertical diffusion coefficient.
The scond stage is advection/diffusion model(scond moment method) which uses the results of the first stage as input data.
First, wind fields on Korean peninsula for none synoptic scale wind showed typical land and sea breeze cirulation, and the emitted particles were transported by sea breeze for daytime, emissions return to sea by land breeze for nighttime.
Hence, more detailed work needs to be carried out in the future.
