Abstract

Abstract. A semi-analytical solution to an advection–diffusion equation is coupled with a nonlinear wavemaker model to investigate the effect of strong nonlinearity on wave-induced mixing. The comparisons with weakly nonlinear model predictions reveal that in the case of waves of higher steepness, enhanced mixing affects the subsurface layer of the water column. A fully nonlinear model captures the neglected higher-order terms from a weakly nonlinear solution and provides a reliable estimation of the time-mean velocity field. The corrected wave-induced mass-transport velocity leads to improved estimates of subsurface mixing intensity and ocean surface temperature.

强非线性对波浪诱导的垂直混合的影响

摘要。本文将平流扩散方程的半解析解与非线性造波器模型耦合，研究了强非线性对波致混频的影响。与弱非线性模型预测的比较表明，在波浪陡度较高的情况下，增强的混合影响了水柱的次表层。完全非线性模型从弱非线性解中捕获被忽略的高阶项，并提供可靠的时均速度场估计。修正后的波致质量输运速度可以改善对地下混合强度和海洋表面温度的估计。

期刊介绍： Earth System Dynamics (ESD) is a not-for-profit international scientific journal committed to publishing and facilitating public discussion on interdisciplinary studies focusing on the Earth system and global change. The journal explores the intricate interactions among Earth's component systems, including the atmosphere, cryosphere, hydrosphere, oceans, pedosphere, lithosphere, and the influence of life and human activity. ESD welcomes contributions that delve into these interactions, their conceptualization, modeling, quantification, predictions of global change impacts, and their implications for Earth's habitability, humanity, and the future dynamics in the Anthropocene.
