综述了海气界面气体交换的物理性质。为了描述边界附近液体中气体的转移，使用了分子加涡流扩散率的概念，该概念已被发现对固体表面上的平滑流动很有用。考虑边界条件，至少在没有波的情况下，对于气/液界面下的流动，可以推导出类似的涡流扩散率与距离的依赖关系。然后讨论了波浪的影响。从尺度上考虑，重力波的影响显然是很小的。从风洞工作可知，毛细波大大增强了气体的传递。现有的假设显然不足以解释这些观察结果。对现场数据的检查更令人沮丧，因为数据没有显示预期的气体交换随风速的增加。DOI: 10.1111 / j.2153-3490.1980.tb00974.x
The physics of gas exchange at the air-sea interface are reviewed. In order to describe the transfer of gases in the liquid near the boundary, a molecular plus eddy diffusivity concept is used, which has been found useful for smooth flow over solid surfaces. From consideration of the boundary conditions a similar dependence of eddy diffusivity on distance from the interface can be derived for the flow beneath a gas/liquid interface, at least in the absence of waves. The influence of waves is then discussed. It is evident from scale considerations that the effect of gravity waves is small. It is known from wind tunnel work that capillary waves enhance gas transfer considerably. The existing hypotheses are apparently not sufficient to explain the observations. Examination of field data is even more frustrating since the data do not show the expected increase of gas exchange with wind speed. DOI: 10.1111/j.2153-3490.1980.tb00974.x
