摘要
风浪破碎是海中气泡的主要成因。先前的研究基于理论计算和数值模拟,揭示了海中气泡对光散射和海水反射比有不可忽略的影响。利用海洋光学和海面风速现场观测数据,结合Mie散射理论计算和海中光辐射传递数值模拟,研究风浪破碎产生的海中气泡对海水反射比的影响。现场观测和数值模拟结果表明,在光学性质稳定的I类海水中,不同风速下海洋光学反射比的不同主要源于海中气泡的贡献。
Bubbles in the upper ocean are primarily produced by breaking waves.Previous studies based on theoretical computations and numerical simulations revealed that bubbles have a non-negligible effect on light scattering as well as ocean reflectance.In this paper the effect of bubbles generated by breaking waves on ocean reflectance was investigated by using the field measurements of ocean optics parameters and wind speed,and Mie theory and radiative transfer modeling.The results from field observations and numerical simulations suggested that for optically stable case I water differences in ocean reflectance under different wind conditions were resulted from contributions of bubbles.
