Earth surface heat balance changes caused by urbanization
AbstractThe relationships, in regional environmental planning, between land use and earth surface heat balance in urbanized areas have been investigated.In the first part of this study, the calculation procedure and field observations of earth surface heat balance (natural heat) are described. The summer earth surface temperature was observed at Tokyo. Calculated values showed good agreement with observed values, though observed surface temperatures varied widely with differing land use.The results of an Osaka Prefecture (1856 km2) case study are also presented. The amount of natural heat (the earth surface heat balance) and the artificial heat released are estimated according to land usage. The regional mean earth surface temperature in Osaka City (a developed region) during August is higher by ca. 3 °C than it is in Sennan district (an undeveloped region). The artificial heat released was 174.2 × 1012 kcal/year in Osaka Prefecture (1970 – 1974). The heat flow at the earth's surface varies remarkably with urban development.
