为了理解和模拟与大气和海洋相关的许多物理过程,有必要考虑两者如何耦合。空气-海洋的动量、热量和质量通量是连接两种流体的关键量。然而,由于海上通量的测量非常困难且成本高昂,特别是在模型输入所需的时间和空间尺度上,因此长期以来它们一直根据更容易获得的平均参数和体积交换系数进行参数化。在本文中,我们回顾了参数化海气湍流通量的现有技术。在八次现场实验期间编译的涡相关通量数据集代表了各种条件,用于研究传统的整体通量参数化(即风速相关动量系数、恒定的感热和潜热系数)以及几种最新的算法。特别强调海况对通量的影响。
In order to understand and model many physical processes relating to the atmosphere and ocean, it is necessary to consider how the two are coupled. The air–sea fluxes of momentum, heat, and mass are the key quantities linking the two fluids. However, since fluxes over the sea are difficult and costly to measure, especially over the time and space scales required for model input, they have long been parameterized in terms of more readily available mean parameters and bulk exchange coefficients. In this paper we review the present state of the art of parameterizing air–sea turbulent fluxes. A data set of eddy-correlation fluxes compiled during eight field experiments, and representing a wide range of conditions, is used to investigate traditional bulk flux parameterizations (i.e. wind-speed dependent momentum coefficients, constant sensible and latent heat coefficients), as well as several more recent algorithms. Particular emphasis is given to the effect of sea state on the fluxes.
