内蒙古奈曼流动沙丘下垫面近地面能量收支研究
Study on the Energy Budget in the Surface Layer Over Movable Dune at Naiman in Inner Mongolia
利用2000年7月18日—8月12日在内蒙古奈曼流动沙丘下垫面取得的大气边界层观测资料，分析了地表能量收支各项的日变化、总体输送系数日变化及其与稳定度的关系；比较了涡旋相关法、波文比—能量平衡法所得到的感热通量。得到奈曼流动沙丘下垫面平均地面阻曳系数Cd为4.69×10-3；感热通量总体输送系数 为2.25×10-3。在近中性层结条件下，Cd和Ch分别为4.83×10-3和1.34×10-3。近地面层湍流方差在不稳定层结下均满足Monin-Obukhov相似理论。
Using the data observed over movable dune in Naiman from18 July to 12 August 2000, diurnal variation of the surface energy budget and the bulk transfer coefficients, the relation between the bulk transfer coefficients and the stability are analyzed. The sensible heat flux calculated by the eddy correlation and Bowen ratio methods is compared. The analysis of the bulk transfer coefficients shows that in the surface layer over movable dune, the average drag coefficient Cd is 4.69×10-3 and the average bulk transfer coefficient of sensible heat Ch is 2.25×10-3. Under the near neutral stratification, Cd and Ch are respectively equal to 4.83×10-3 and 1.34×10-3. The turbulent variances in the surface layer satisfy the Monin-Obukhov similarity theory under the unstable stratification.
