Observations On The Thermal Effects of River Water On Urban Climate Study on heat budget on water surface and its effects on Surrounding areas of Sumida River

摘要

Water bodies in urban area have been expected to mitigate the urban heat island as well as green space. In this paper, we showed the results of observations about heat budget at river water and moving observations to clarify horizontal extent of its thermal effects. Diurnal variations of sensible heat flux estimated by several methods corresponded closely with each other, though These values didn't exceed 100W/m~ even in the peak about midday. Estimated heat storage term occupied more than 90/100 of net radiation during daytime.
