This paper predicts the effects of the capital relocation on a thermal environment using a meso-scale meteorological model. Five candidate cities, Tomakomai, Nasu, Hamamatsu, Toki and Ueno, are chosen for study areas.
The simulation results show that temperature will rise in all the candidate cities after the relocation. The temperature rise averaged over a day is from 0.5 to 1.0 degree centigrade in each candidate city. In the coastal candidate cities, Tomakomai and Hamamatsu, the temperature will rise not only in new capital regions but also in the leeward regions because of the sea breeze.
Relative contribution of land cover changes and anthropogenic heat to the temperature rise are also compared. The temperature rise in the daytime is brought mostly by land cover changes. At night the influence of anthropogenic heat becomes large, and in some candidate cities it becomes greater than that of land cover changes. These results imply the energy-saving at night is effective for controllingthe temperature rise in a new capital.
