Spatial Distribution and Temporal Variation of Soil Moisture over China. Part II: The Evaluations for Coupled Models’ Simulations

  • Soil moisture simulated with 14 representative ocean-atmosphere-land system models is evaluated over China using observational data. The results show that the observed spatial patterns of soil moisture are captured by almost all coupled models. But the seasonal cycle and the interannual variation are poorly simulated by most coupled models. The relationship between soil moisture and precipitation is well simulated by most coupled models, but the relations are too stronger in some coupled models. The poor simulations of precipitation are one of the reasons for the poor simulations of soil moisture by coupled models. The soil moisture simulated by high-resolution models (horizontal grid systems higher than 1.875°×1.875°) is generally better than those simulated by low-resolution (horizontal grid systems lower than 1.875°×1.875°) and medium-resolution (horizontal grid systems between 1.875°×1.875°and 3.75°×3.75°) models in the spatial pattern and the interannual variation of the annual and summer means. However, the superiority of medium-resolution models relative to low-resolution models is not apparent.
