| 摘 要： | 本文用一维的土壤—大气耦合模式,讨论了蒸发过程中,土壤性质对大气边界层的影响。数值试验结果表明:在完整蒸发过程中,土壤性质对大气边界层影响表现出明显的非线性三阶段特征。在各个阶段,土壤性质的影响程度是不同的,第二阶段影响最大,该阶段对应的土壤含水量处于凋萎系数以上、某一临界值以下范围;在土壤水分高于临界值的第一阶段,土壤含水量和质地的差异对边界层影响很小。大气边界层演变的三阶段特征主要是由土壤水分特性所决定,数值结果与已有观测事实和理论分析结果是一致的。

| Abstract: | This paper discusses the influence of soil property on
planetary boundary layer during evaporation process using one dimensional soil-atmosphere coupled model. The results show that the development of PBL can be divided into three stages during evaporation process. Soil property has influence upon this development. The influence of soil property is obvious at stages two and three. The agreement between calculated values and the observed facts shows that this model has considerable reliability. |
