Abstract
This study investigated the effect of parked cars in the sunshine on the increase of air temperature on a sunny day. Air temperatures were determined both from inside of the parked cars and the top surface of the vehicle at which one car was parked under the sunshine and the other in the shade for the duration of 27 hours. The surface temperatures of asphalt and bare soil were simultaneously measured in both locations, sunshine and shade areas, along with a couple of meteorological factors. The sensible heat fluxes from the surfaces of asphalt, bare soil and two vehicles were estimated by utilizing those observed data. The results are as follows; 1) The surface temperatures of bare soil, asphalt and two vehicles increased with $30{\sim}37^{\circ}C,\;37{\sim}46^{\circ}C\;and\;42{\sim}49^{\circ}C$ respectively during the day. 2) The sensible heat fluxes were noticeably higher from the top surface of the parked vehicle in the sunshine than from the asphalt or bare soil. The differences of sensible heat fluxes between the vehicle's roof and the other two surfaces of asphalt and bare soil were 60 (asphalt) and 85 (bare soil) $W/m^2$ during the daytime.
