一、引言海气交界面的特征是在非常小的垂直距离上,耦合的两种流体的密度发生了非常明显的变化。每种流体的边界层测量值表明,靠近交界面处风和海流都近似按对数廓线分布。例如,Sheppard等(1972年)和Csanady(1984年)的结果。这些廓线可以外推到每一种流体的粗糙度长度上,尽管由于概念和实验的困难使得这种外推的检验实验很难进 I. INTRODUCTION The characteristic of the sea-air interface is that at very small vertical distances, the density of the two coupled fluids undergoes a very significant change. The boundary layer measurements for each fluid show that the winds and currents near the interface are approximately log-log profiled. For example, the results of Sheppard et al. (1972) and Csanady (1984). These profiles can be extrapolated to the roughness length of each fluid, although this extrapolation is difficult to test due to both conceptual and experimental difficulties
