Outline of Final Research Achievements

The final objective of this study was to make a planning support tools that indicates "which areas" and "which countermeasures" should be used to mitigate urban warming effects. This was studied by analysing the characteristics of the current and future urban climate using large-scale numerical simulations with the coupled atmosphere-ocean model MSSG.
Throughout the research period, numerical simulations by MSSG were conducted for several cities in Japan, with a focus on Fukuyama City, Hiroshima Prefecture, to analyze the characteristics of both the current and future urban climates. Based on these simulation results, prototypes of planning support tools aimed at realizing urban climate mitigation in each city are also created.

Academic Significance and Societal Importance of the Research Achievements

本研究を通して作成を進めてきた「計画支援ツール」は、「どのようなエリア」に「どのような都市高温化対策」を用いれば、都市高温化緩和型の都市づくりが行えるかを示すものであり、地球温暖化の進行に伴い暑熱環境が悪化していく時代における安心・安全な都市空間の創出につながる点で、社会的な意義は大きいと考えられる。
また都市気候の数値シミュレーション（MSSG）や将来気候のデータベース（d4PDF）を活用してこのようなツールを作成することは、環境分野の分析結果に基づいた都市づくりのあり方を考えていくという点で、都市計画分野における学術的な意義も大きいと考えられる。
