原始语种摘要: This paper describes the implementation of an improved soil thermodynamics inthe hydrological module of Earth system model (ESM) developed at the InstitutPierre Simon Laplace (IPSL) and its effects on land surface meteorology inthe IPSL climate model. A common vertical discretization scheme for the soilmoisture and for the soil temperature is adopted. In addition to the heatconduction process, the heat transported by liquid water into the soil ismodeled. The thermal conductivity and the heat capacity are parameterized asa function of the soil moisture and the texture. Preliminary tests areperformed in an idealized 1-D (one-dimensional) framework and the full model is then evaluatedin the coupled land–atmospheric module of the IPSL ESM. A nudging approach isused in order to avoid the...
