Abstract
We developed a numerical model which can evaluate the outdoor heat stroke risk as a regional mesh map, and then simulated that risk in the Osaka city area during the 2007 summer. The calculation resulted in regional difference of the heat stroke risk within the Osaka city subdivided into 500-m mesh. That risk strongly had a positive correlation with the average sky view factor of meshed district due to daytime radiative influence. Differences not only in district-structure parameters (e.g., sky view factor ) but also in climate characteristics were attributed to regional differences of the risk. Our simulation method by regional mesh calculations combining a mesoscale meteorological, urban, and human scales was available for regional heat stroke prediction.
