A Discussion of Green Environment Based on Climate Analysis Maps with WRF Model in Sakai City

Abstract

In this study, to explore the ideal green environment for mitigating high temperatures in Sakai City, we used the meso-scale meteorological model WRF to analyze the current climate in August 2020 and the climate under the scenario of conservation and maintenance of the green environment with reference to the green future vision map of the ""Basic Plans for Greening,"" and created and compared the respective climate analysis maps.The results showed that during the daytime, the effect of the area greening was larger in the inland area, which is less affected by sea winds, and smaller in the coastal area.During the night, the temperature reduction effect of the green maintenance of the axis was clearly observed. In addition, it was suggested that the preservation of the existing hills and conservation and improvement of adjacent farmland will promote the effect of cool air flow and mitigate the high temperatures due to the integrated green environment.
