Development of a simulator for urban climate analysis reflected urban planning and climate change scenarios

When making urban planning, it is important that to understand climate effect caused by urban structural changes. Seoul city operates Urban Plan Information System (UPIS) which provides information on urban planning scenario. The technology for analyzing climate effect due to urban planning needs to be developed by linking urban planning scenario provided by UPIS and climate analysis model called to Climate Analysis Seoul (CAS). CAS was developed for analyzing urban climate conditions to provide realistic information considering local air temperature and wind flows. Quantitative analyses are conducted by CAS for the production, transportation, and stagnation of cold air, wind flow and thermal conditions by incorporating GIS analysis on land cover and elevation and meteorological analysis from Meteorology and atmospheric photochemistry meso-scale model (MetPhoMod). In this study, the analysis of climate impact before and after creating the green area is done, which is part of 'Connecting green areas across the north and south of Seoul' plan, one of the '2020 Seoul urban basic plan'.
