초록

Urban air mobility (UAM) is emerging as a solution to alleviate traffic congestion in urban areas. For the successful implementation and stable operation of UAM, acquiring high-resolution meteorological data, particularly wind, is essential. Despite the existence of various studies that have assessed meteorological downscaling systems, there is little research focusing specifically on the urban environment, where the dynamics of wind and weather patterns are more complex. In response to this need, our study advances and introduces a sophisticated downscaling system designed to facilitate high-resolution (100 m) wind speed simulations based on module in IMPROVER (Integrated Model post-PROcessing and VERification) from Met Office. This system takes into account intricate surface details, including orography, and the characteristics of urban landscapes are represented to enhance simulation accuracy and realism by incorporating the indirect effects of urban buildings. The system is quantitatively evaluated by Pearson correlation coefficient, root mean square error, and mean bias error, demonstrating better correlation and improved predictability relative to raw meteorological data. These results emphasize the significance of downscaling system specialized for urban areas, highlighting its contribution to reliable and realistic wind conditions.
