夏季の名古屋の温熱環境を対象とした現状再現の精度検証と疑似温暖化手法を併用した将来予測の試み: 領域気象モデルWRFによる名古屋都市圏の温熱環境シミュレーション（その1）

摘要

本研究では、世界最新の領域気象モデルWRFを用いて、名古屋rn都市圏における温熱環境の現状再現シミュレーションおよび2070rn年代の将来予測の試みを行った。将来予測に関しては、3つの温暖rn化対策を施した場合の気温低減効果についても検討した。rn（1）現状再現シミュレーションの結果はアメダス観測データと良いrn一致を示した。%Nagoya, which is located in the central part of Japan, is one of the fastest growing cities in Japan. Like other big cities, the problems associated with urban heat islands are very serious in the Nagoya metropolitan area. The increase in the annual-mean surface air temperature for the last 100 years is 2.7℃, and a further increase will likely occur in the future. In this study, an attempt to project a thermal environment in the summers of the 2070s in the Nagoya metropolitan area was conducted by using a regional atmospheric model, WRF. Pseudo global warming data generated by a general circulation model, which was based on the A2 scenario of IPCC Forth Assessment Report, were used for the initial and boundary conditions in the WRF computations. We also carried out a numerical investigation of the present thermal environment and compared the difference between the present and future status of the thermal environment in the Nagoya metropolitan area. Furthermore, numerical experiments involving the introduction of several countermeasures to improve the projected thermal environment in the summers of the 2070s were performed, and the effects of each countermeasure were quantitatively investigated.
