摘要
本文根据边界层气象学的最新成果提出两个由常规海上气象观测资料求阻力系数C_D的方法,一个由海气温差及10米高处的风速,另一由地转风速及边界层上下界之间的位温差△θ,此二法可直接应用于实际计算及模式中求C_D。
In this paper, two Methods for computing the drag coefficient CD in air over sea have been suggested by use of the routine meteorological observation over sea according to the newest achievement of the boundary layer meteorology, one is to apply the air-sea temperature difference and the wind speed at 10m height, another is to use geostrophic wind speed and the difference of the potential temperature between the top and bottom of the PBL, these two methods can be used to compute CD in practice and models.
