| 摘 要： | 本文利用南极瑞穗站１９７９—１９８０年近地面层微气象及辐射平衡等观测资料，分析了春、夏、秋和冬季辐射平衡分量的日、年变化特征，采用空气动力学方法和廓线梯度迭代法计算了不同季节的动量通量、感热通量和由能量平衡方程得到的潜热通量的日变化特征，并对计算结果进行了比较。文中还对湍流热量交换系数、湍流动量交换系数与理查孙数的日变化关系进行了讨论。

| Abstract: | Using measurements in micrometeorology and radiation balance in the surface layer in Mizuho Station, the diurnal and annual variation characteristics of radiation balance in spring, summer, autumn and winter are analyzed, and the momentum flux and the sensible heat flux in different seasons are calculated by the aerodynamic method and the profile gradient alternate method. The diurnal variation characters of the latent heat flux from the equation for energy balance are also obtained. The results from the calculation are compared. Finally, the relationship between the turbulent heat and momentum exchange coefficient and the diurnal variation of the Richardson number is discussed. |
