项目摘要

The authors observed the parameters of the physiological thermal indicator SET* (air temperature, relative humidity, wind speed, sky radiation, surface temperature) at five observation points within 100m from the restored zone and the stream in mid August in 2003-2006.They observed the surface temperature with a thermography camera, and upward sensible heat flux using a scintillometer. They further utilized the time series analysis of air pollutants observed by Seoul Metropolitan Government. Movement of cool air mass along the restored river was numerically simulated by applying a CFD model, taking into account swirls developing at road crossingsBased on observation with ultra-sonic anemometers in 2006, it was clarified that with the sea breeze along the Cheong-Gye Stream, cool air mass is able to spread approximately 80m from the restored zone.In the total monitoring in 2007, the objective was to prove the meteorological mechanism of the processes that convey the cool air from the river to urbanized area. The authors set up poles at the middle of the river and at the southern and northern riversides, where they measured air temperature and relative humidity.As for the cooling effects by water, air temperature gets lower and water vapor pressure gets higher at closer distances to the surface of the river. At the southern riversides, air temperature was relatively lower than at the northern riverside.On the other hand, at the northern riverside, air temperature near the surface is often higher during daytime. As the cause, it was considered that the surface of northern riverside was concrete pavement though southern riverside was vegetational pavement. These results therefore indicate that a layer of cool air was generated in the southern riverside.

2003- 2006年8月中旬，在距恢复区和溪流100 m范围内的5个观测点，观测了生理热指标SET*（气温、相对湿度、风速、天空辐射、地表温度）的参数。他们进一步利用了首尔市政府观测到的空气污染物的时间序列分析。利用CFD模型对冷气团沿着修复河道的移动进行了数值模拟，并考虑了在道路交叉口处形成的漩涡。根据2006年使用超声波风速计进行的观测，明确了随着海风沿着清溪流，冷气团能够从修复区域传播约80 m。在2007年的总监测中，目的是证明冷空气从河流输送到城市化地区过程的气象机制。作者在河流中部、南北北方河岸设置了观测点，测量了气温和相对湿度。至于水的冷却作用，离水面越近，气温越低，水汽压越高。在南部河岸，气温相对低于北方滨江，而在北方滨江，近地面的气温往往在白天较高。究其原因，认为是北方滨江表面为混凝土路面，而南方滨江为植被路面。因此，这些结果表明，一层冷空气产生在南部滨江。
