Observations of heat flux in an urban area with a large pond by kytoons

Abstract

There are few studies on the thermal environment in urban areas, considering the convective heat flux by natural wind and covering materials on the ground surface. In this paper, the heat flux is calculated from the profiles of the wind speed and the air temperature, which are simultaneously observed by kytoons at three points in an urban area with a large pond, to examine the difference between the built-up area and the water surface, and to make clear the relation between the convective heat transfer and the wind speed.
