In this paper, we investigate the effects of land-use scale on regional mean heat fluxes and the validity of the heat flux pa-rameterization by using fractional area. We use SiBUC for the land surface processes and LCM for the atmospheric circulation. As the simulation domain, we choose the periodic pattern of two land-use conditions (forest-urban, urban-water, and forest-water).
As a result, the scale effects appear differently depending on the combination of the land-uses. And the heat flux parame-terization based on fractional area is not valid when the domain includes water body and urban area.
