To study the influence of the meteorological field preparation method on the Ozone concentrations, comparative numerical study on the different resolution scales of the bottom boundary conditions such as topography and urban building factors were carried out. Buildings in the city acts as a cause of distorted wind direction, wind speed, causing the stagnation of the air flow. In the recent trend of climate change can not but consider the temperature rise of the urbanization. Based on this, to make the city effectively respond to climate change may require a long-term restructuring of urban spatial structure. This study was aimed to analyze the ozone concentration of planetary boundary layer in different artificial constructions areas which has a direct impact on urban climate, and estimating the warming phenomena. MM5(Meso was used to consider the urban structure associated with urban growth in order to precisely determine the impact of the building on the weather condition of the city. We examined a comparative study of topography with different horizontal resolutions and building parameter information on the meteorological fields. By using the practical and detailed orographic feature and urban building contribution factor, we analyzed the great differences in ozone concenfration. The prognostic meteorological fields and air quality field over complex area of Seoul, Korea are generated by the PSU/NCAR mesoscale model (W5) and the Third Generation Community Multiscale Air Quality Modeling System (Models- 3/CMAQ), respectively in complex urban areas. A comparison study of the meteorological fields with different resolutions revealed substantial localized differences in surface temperature and zonal wind flow fields. One of the notable findings is the differences in the results of urban topographies. These differences on mixing height(PBL) indicate that changes in detailed condition lead to regions of increased wind speed, more converged current and increased predicted Ozone concentration.
