    Abstract

    This paper describes the first order impacts of incorporating a complex land-surface scheme, the Bare Essentials of Surface Transfer (BEST) into the Australian Bureau of Meteorology Research Centre (BMRC) global atmospheric general circulation model (AGCM). A two-year climatology from the AGCM with BEST has been compared with a ten-year simulated climatology without BEST. The wintertime simulations with BEST show significant improvements especially over the Northern Hemisphere mainly due to the more realistic treatment of snow cover. However, the summertime simulations with BEST are worse than those from the current BMRC AGCM due to the poor specification of albedo and roughness length. Incorporating BEST into the BMRC AGCM leads to an overall reduction of surface wetness, evaporation, cloud cover and precipitation, results consistent with findings by other authors.
