It is found that the NCAR CCM1 T42 simulation provides good large-scale precipitation patterns, and that the MM4B produces the most accurate regional detail. It is suggested that to investigate continental-scale processes, AGCMs need to use a horizontal resolution which approximates or is finer than 3° × 3°. For the investigation of climate impact or land-surface change at the regional scale, a 70 km resolution, achieved by embedding a mesoscale model within an AGCM, seems to provide considerable potential.
