Abstract: In this paper, two dimensional numerical model coupling land surface processes with atmosphere is developed. SiBUC is used for the land surface processes and LCM is for the atmospheric model.By using this model, some experiments are carried out for studying the effect of land-use scale on regional mean heat fluxes.The validity and limitation of the heat flux parameterization using fractional area are investigated, too.The periodic pattern of two land-use conditions is used for simulation domain, changing the size and combination of each land-use.Their experimental results show that the scale effects appear differently depending on the combination of the land-use. Especially, in combination of urban area and water body, the scale effect is large, and the fractional area heat flux parameterization is not valid.A new heat flux parameterization scheme, which can incorporate the effect of land-use scale, is proposed from the simulation results.
