A Study on Parameterization of Turbulent Characteristic Amounts at Near Surface Layer
-
摘要: 以地表能量收支平衡方程为基础，将地表通量同近地层内的常规气象资料联系起来，模式要求输入地面风速、温度和总云量等常规气象观测资料，输出近地层的湍流特征参数U* 、θ* 、L和参数化的地表通量（净辐射、感热通量、潜热通量和土壤热通量），澳大利亚Wangara试验资料被用来检验了该模式。计算结果和实际资料吻合较好。

Abstract: On the basis of the surface energy buget equation, the surface turbulent fluxes are estimated from routine meteorological data. The inputs required by the model are surface wind speed, temperature and total amount of cloud. The outputs of the model are turbulent characteristic parameters and parameterized surface fluxes. The boundary layer data of the Wangara Experiment are used to verify the parameterization model. The calculated results are in good agreement with the observed values -
