Abstract

The results of the VIC fixed runs (15 cm) showed that global average soil moisture was considerably lower (about 2.5 cm on average) as compared with the bucket runs, global evaporation and precipitation were reduced, and surface temperature was increased, especially in the Northern Hemisphere in summer. The results argue for representation of the surface hydrology in GCMs with two-layer soil models, which are capable of representing the cycling of moisture during dry periods by means of surface evaporation, which is generally underestimated by single-layer models. -from Authors
