| 内容記述 | The purpose of this study is to clarify the effects after the restoration of Cheonggye stream in Seoul, in order to pursue effective methods to mitigate the summer thermal stress in mega-city. The results of field observation in the summer of 2004 and 2007 summer showed that the stream-effect as a cooling source was confirmed. In the south of the stream, temperature changes were smaller than in the north of the stream. The asymmetric pattern of temperature distribution across the stream is associated with wind direction as well as urban morphology. In particular, around 1 9:30 LST, the maximum difference between air temperature on the bridge and surrounding streets was over 2.5℃. The appearance of the obvious low temperature was proportional to the extent of stream-effect, and it was also affected by wind speed and direction. In cloudless night, the temperature difference continued until the sunrise. In 19:30-0:00 LST, the temperature difference was over 1℃ on the north side of the stream, and the discernible reduction in air temperature was spread to the extent about 70-80m. On the other hand, the temperature difference was around 0.5℃ on the south side of the stream, and the discernible reduction in air temperature was spread to the extent only 30-50m. From those results, the authors suggest that the environment design of wind path over the stream should be developed in order to improve the stream-effect. In addition, the authors indicate the bank along the stream side may obstruct the diffusion of cooler air-mass above the stream. | |||||||||
