| Zusammenfassung |
| A parameterisation to incorporate the effects of frozen soil on modelled
hydrology is described and implemented within a land surface model, the
Joint UK Land Surface Environment Simulator. It is shown to generally
improve the modelled flow of Siberian rivers compared to observations,
specifically in seasons of freezing or thawing soil. Most noticeably, the
revised model increases the snowmelt flow peak by 26–100% compared to the
control model, thereby better matching observed flows. The model physics
resulting in the changes to river flow are discussed and attention is given
to the effect of inaccuracies in snowfall driving data which can hinder the
comparison of new model processes. |
