摘要
本文利用一维土壤-大气耦合数值模式,对土面蒸发过程进行了模拟研究。模式较好反映了蒸发过程三阶段的趋势特征,并试验了不同土壤性质、太阳辐射强度和地转风速对蒸发过程影响。模式还揭示了蒸发过程中,土面热量平衡各分量相互转换过程。
Based on the theory of the planetary boundary layer and the soil-water dynamics, one dimensional soil-atmosphere coupled numerical model is proposed. The evaporation process in soil-atmosphere system is simulated by the model. The results show that the evaporation can be divided into three stages with the variety of soil moisture near the surface. Soil property is an important influence factor of this process. Finally, paper discusses the variety of the evaporation process with the amount of geostrophic wind speed and solar radiation.
