説明
Field data obtained at Ara river flowing through metropolitan Tokyo area were analyzed to evaluate the effect of urban rivers on the microclimate of the adjacent city region. The data obtained at the fixed stations revealed that the temperature in the river course is usually low in the diurnal time of summer and is high in the nocturnal time of winter, compared with the ensembly-averaged temperature of the surrounding city region. It is observed that the temperature difference affects the temperature recorded at the stations which locate downwind area of the river, where the air is cooled in summer and warmed in winter. The data collected by using the captive balloons showed that the atmosphere exchanges heat with the water surface and the vegetated flood plains. It is found that the flood plain plays an important role in exchanging heat, especially in summer season. Computations of internal boundary layer which developes in the river course showed the formation process of the vertical temperature and humidity profiles.
