| Abstract: | This paper gives a parameterization of frozen soils model for study of the interactional cycle.Regarding the two important problems,seasonal snowpart and frozen soils,the inner complex interactional water,heat transport,and phase change physical process are simplified and improved.An improved parameterization scheme is proposed.Finally,the observation data from several overseas and internal stations are used to validate the model.Simulated results are in good agreement with the observed data,implying that the snowpack and frozen soil parameterization scheme is applicable to the study of the interactional cycle. |
