Soil thermal conductivity parameterization establishment and application in numerical model of central Tibetan Plateau
青藏高原中部土壤热传导率参数化方案的确立及在数值模式中的应用

Based on soil thermal conductivity parameterization of Farouki, Johansen and C té, a new soil thermal conductivity parameterization scheme of central Tibetan Plateau has been established. The new soil thermal conductivity parameterization has been verified by the observed data of Bujiao (BJ) site in the Coordinated Enhanced Observing Period Asia Australia Monsoon Project on the Tibetan Plateau (CAMP/Tibet). And an off-line numerical simulation experiment by Common Land Model (CoLM) with new soil thermal conductivity parameterization scheme on the Tibetan Plateau is presented. The results show that in both unfrozen and frozen soil, the calculated soil thermal conductivity by the new scheme is better than Farouki scheme. The soil temperature simulation of CoLM with new soil thermal conductivity is better than that of original CoLM.
