abstract
We discussed the heat and moisture transfer in Tokyo area under fine weather conditions with emphasis on spatial and temporal variation in humidity. First, we processed hourly meteorological data at several stations in the central part of Tokyo in mid-winter and mid-summer. It was found that in winter sea breezes may bring humid air into urbanized area to increase the absolute humidity while in summer the evolution of boundary layer is more influential over the humidity level than sea breeze intrusion. Then we applied our urban climate model that considers the moisture release from cars and human bodies to Tokyo area under idealized summer weather condition. It was indicated that the moisture release accompanied by the above human activities contributes little to the humidity level and that the vapor supply from land use and advection such as sea breezes are more important processes in the humidity distribution.
