| Zusammenfassung |
| The Tibetan Plateau is a critical region in the research of
biosphere-atmosphere interactions on both regional and global scales due to
its relation to Asian summer monsoon and El Niño. The unique environment
on the Plateau provides valuable information for the evaluation of the
models' surface energy partitioning associated with the summer monsoon. In
this study, we investigated the surface energy partitioning on this important
area through comparative analysis of two biosphere models constrained by the
in-situ observation data. Indeed, the characteristics of the Plateau
provide a unique opportunity to clarify the structural deficiencies of
biosphere models as well as new insight into the surface energy partitioning
on the Plateau. Our analysis showed that the observed inconsistency between
the two biosphere models was mainly related to: 1) the parameterization for
soil evaporation; 2) the way to deal with roughness lengths of momentum and
scalars; and 3) the parameterization of subgrid velocity scale for
aerodynamic conductance. Our study demonstrates that one should carefully
interpret the modeling results on the Plateau especially during the
pre-monsoon period. |
