论文摘要
在秋天至冬季，在罗斯海北部收集的一个非常大的观察数据集应用了模型数据倒置，从而估计了海冰的频率依赖性耗散率。建模平台是Wavewatch III（R），其说明非平稳性，对流，波浪产生和其他相关过程。由此产生的9477耗散曲线与其他变量（例如冰厚度）共同分居，以量化以后的研究中可能利用的相关性，以改善预测。来自反转的平均耗散曲线适用于简单的二项式。平均轮廓的可变性并不小，但是二项式与先前基于基于观察的耗散估计的质量相似，并且功率依赖性与至少三个理论模型一致，其中一种假设耗散是由冰 - 冰水界面上的剪切而产生的。
A model-data inversion is applied to a very large observational dataset collected in the Southern Ocean north of the Ross Sea during late autumn to early winter, producing estimates of the frequency-dependent rate of dissipation by sea ice. The modeling platform is WAVEWATCH III(R) which accounts for non-stationarity, advection, wave generation, and other relevant processes. The resulting 9477 dissipation profiles are co-located with other variables such as ice thickness to quantify correlations which might be exploited in later studies to improve predictions. Mean dissipation profiles from the inversion are fitted to simple binomials. Variability about the mean profile is not small, but the binomials show remarkable qualitative similarity to prior observation-based estimates of dissipation, and the power dependence is consistent with at least three theoretical models, one of which assumes that dissipation is dominated by turbulence generated by shear at the ice-water interface.
