A. Mochida et al., CFD ANALYSIS OF MESOSCALE CLIMATE IN THE GREATER TOKYO AREA, Journal of wind engineering and industrial aerodynamics, 67-8, 1997, pp. 459-477
The results of CFD analyses of mesoscale climate in the Tokyo area are
presented. Here, the model for geophysical flow problems developed by
Mellor and Yamada is used for turbulence closure. In the First half o
f the paper, the accuracy of CFD analyses is examined by comparing the
ir results with the measured data. The topography and present land-use
situation in Japan are incorporated into the predictions by using the
numerical data-base provided by the National Land Agency of Japan. Fo
r comparison, a computation which does not consider the effects of the
distribution of land-use conditions at the present is also carried ou
t. In the latter part, urban climates during the 1930s and the 1990s a
re analysed by the CFD method developed here. By comparing the results
of these analyses, the effects of urbanization on heat island circula
tions over the Tokyo area are investigated.
