DETERMINATION METHOD OF COEFFICIENTS AND ITS PROBLEMSIN THE SIMULATION OF URBAN AIR TEMPERATUREBASED ON ONE DIMENSIONAL HEAT BUDGET MODEL

摘要

It is required that the urban air temperature isrnestimated on the average and macroscopically forrnstudying the urban thermal environmental problemsrnin summer. The diurnal variations of urban airrntemperature and heat budget components arerninvestigated using one dimensional heat budgetrnmodel. The evaporative efficiency and thernanthropogenic heat were estimated by means ofrninverse operation using the observed air temperature.rnGood coincidence was obtained with the observed airrntemperature and the calculated. The diurnalrnvariations of convective heat flux and latent heat fluxrnpresented unusual variation. The main reasons of thisrnunusual variation are considered the influence of thernadvection effect caused by sea breeze, the transferrncoefficient of surface layer used here, and thernassumption of the thermal properties on the urbanrnearth surface.
