A numerical investigation of present (2006) and future (the 2070s) thermal environments in summer in the Nagoya Metropolitan Area was conducted using the Weather Research and Forecasting (WRF) model. In the future projection, a pseudo-global warming method was incorporated to consider the effects of global warming as background data. Based on the simulation results, analyses of heat balance structures at several locations were also carried out using an urban heat balance model. The heat balance structures between the present and future projections were compared, and the differences in the heat transfer mechanisms between the present and future statuses were investigated.

The current status and remaining issues of coupling CWE models with mesoscale meteorological models (MMM) are reviewed from the view point of computational wind engineers. By way of three examples to demonstrate the typical application areas where the coupling approaches are needed, the governing equations considered, and the difficulties to couple the models despite the different spatial and temporal scales are described. Next, recent attempts of single-model up-scaling of CWE models to meteorological scale wind flow and thermal environment are shown. The need to upgrade existing CWE models for appropriate up-scaling and the issues that require to be solved by the collaboration with meteorologists are pointed out. Finally, the recent achievements attained by other researchers are reviewed and the future directions of CWE studies are discussed. Emphasis is placed on coupling LES with MMM.

The activity of a taskforce to make a guideline for a Diffusion Model based on Computational Fluid Dynamics (DiMCFD) to use for the atmospheric environmental impact assessment is reported. The taskforce was established in 2006 by the Japan Society for Atmospheric Environment. The applicability of DiMCFD to environmental impact assessment may be very large; however, the results sometimes diverge if conditions are not specified adequately. In the first stage, we limited our efforts to the problems of short distance dispersion in urban areas under neutral stability. The consensuses and some results are shown.

Merging WRF and LES models for the analysis of a wind environment in an urban area 査読有り

A WRF-LES computation was carried out for the analysis of a wind environment in the summer in the Nagoya Metropolitan Area, which is located in the central part of Japan. We also performed a single WRF computation with no LES capability and compared the results between the WRF-LES and single WRF computations. The WRF-LES computation predicted a larger magnitude of wind velocity than the single WRF computation. In addition, we are now conducting other WRF-LES computations using the "LES-within-LES" method proposed by Moeng et al. (2007) and using our homemade LES software with an artificial generation method of inflow turbulence.

世界最新の領域気象モデルWRF（Weather Research and Forecasting）を用いて、名古屋都市圏における温熱環境の現状再現シミュレーションを行い（2006年8月を対象）、アメダス観測データとの比較からその予測精度の検証を行った。さらに、Kimuraら（2007）の疑似温暖化手法を用い、バックグラウンドとしての地球温暖化の影響を考慮した2070年代の将来予測も試みた。将来予測に関しては、幾つかの温暖化対策を施した場合の気温低減効果についても併せて検討した。
