The simulation and revision of soil moisture over Tibetan Plateau
青藏高原地区土壤湿度的模拟及订正

In this paper, the soil moisture is simulated by RegCM3 over the Tibetan Plateau. The obtained results are as follows:(1) The simulated annual cycle of soil moisture is consistent with the observation, but the simulations of soil moisture with different land surface conditions are different. (2) In the area with sparse vegetation , the simulated soil moisture is larger than observation in summer and consistent with that in winter, while in the area with lush vegetation, simulated soil moisture is consistent with observation in summer and larger than that in winter. (3) The larger deviation of simulated soil moisture is corresponding to a large deviation of simulated precipitation and temperature.The soil moisture is revised with revised method, and the results show that the debiations of soil moisture and temperature are reduced. The systematic errors of temperature and precipitation are eliminated after revision. We believe that the revised soil moisture and temperature can provide more accurate data over Tibetan Plateau, and be used to calculate the permafrost distribution.
