Investigating the Contribution of Anthropogenic Heat Emission to Urban Heat Island Effect using WRF-UCM Model

摘要

Heat island effect changes the local weather pattern, increases energy costs to offset this effect, and also increases demand for cooling. While considering urban heat island, local effects due to waste heat from anthropogenic emissions from vehicles, factories and machineries should be taken into consideration as well. In this work, WRF model coupled with urban canopy model has been used for meteorological modeling of Kinki region in order to assess the contribution of anthropogenic heat emission towards the formation of urban heat island. We used a detailed urban land-use map and a gridded emission map consisting of spatial and seasonal distribution of anthropogenic heat emission. Using these simulation results we can understand the spatial and temporal behavior of urban heat island effect in more detail.
