Abstract

In order to clarify the daily effects of increasing carbon dioxide level on the regional thermal environment, a two-dimensional numerical analysis was carried out on unsteady heat and mass-transfer. The results indicate a large surface temperature change in the nighttime and in the summer. The nighttime change is proportional to the change in infrared radiation flux from the atmosphere. An interaction between the effects of water vapor and those of carbon dioxide is found only in the daytime. When carbon dioxide is released from an urban surface, the vertical distributions of the air temperature and the pollutant concentration are affected in urban areas.
