A pattern of sensible heat flux shift in community scale for analysing urban thermal vulnerability

In this study, two methods of spatially modeling the thermal environment by sensible heat and temperature were derived, and a more reasonable method for evaluating the thermal vulnerability was found by comparing the areas with high sensible heat and high temperature, It is aimed to find spatial criteria for the improvement of thermal environment. In this study, two methods of spatially modeling the thermal environment by sensible heat and temperature were derived, and a more reasonable method for evaluating the thermal vulnerability was found by comparing the areas with high sensible heat and high temperature. It is aimed to find spatial criteria of improvement. A vulnerability map was derived that reflects daytime temperature in the map of thermal vulnerability typification by sensible heat and climate exposure factors. The correlation value (0.71) of the sensible vulnerability and the spatial distribution of mortality rate was significantly larger than that the correlation value (0.31) of the spatial distribution of temperature vulnerability and mortality rate. It can be illuminated that the method of deriving thermal vulnerable areas based on sensible heat is more objective than the method of evaluating thermal vulnerable areas with existing temperature. In such a distribution, it was verified that sensible heat better reflects thermal vulnerability than temperature. Therefore, a sensible vulnerability map was created based on sensible heat during the day in the climate exposure factor. In addition, six maps such as temperature, sensibility, adaptation, climate exposure, sensitivity, and vulnerability assessment were derived. In this study, the distribution of sensible vulnerability at the community level is derived and is a useful tool for evaluating the thermal environment in the neighbourhood. The method of deriving thermal vulnerable areas by high sensible heat can be a practical technique to reflect the thermal environment in the improvement plan through the characteristics of space. As that can be reflected in establishing an implementable tool of practical plan to improve thermal environment through the characteristics of space, the study results can be used to establish spatial planning standards to improve the thermal environments for sustainability of metropolis.
