Assessment of the Impact of Metropolitan-Scale Urban Planning Scenarios on the Moist Thermal Environment under Global Warming: A Study of the Tokyo Metropolitan Area Using Regional Climate Modeling

Figure 6

Spatial distributions of the alternative urban scenario responses (relative to the status quo urban scenario) in August daytime mean WBGT to (a) the compact city scenario and (b) the dispersed city scenario. Model grids with statistical significant () differences (according to the two-sided Student’s -test) for the compact and the dispersed city scenarios are shown in (c) and (d), respectively. Black circles in panels (c-d) indicate Southern Chiba (SC) area. Model grid points in this area are used for analysis described in Section 4.1.

(a) ΔWBGT (compact)

(b) ΔWBGT (dispersed)

(c) Significance (compact)

(d) Significance (dispersed)
