Abstract

ABSTRACT We study in the linear approximation barotropic Rossby waves in the ocean covered by compressed ice. We derive the dispersion relation and analyse its dependence on the degree of ice compression and its flexural rigidity. The characteristic parameters of a wave-field the most sensible to the influence of ice cover are estimated and presented for the Earth and some other planets. The main conclusion is rather pessimistic as the influence of ice cover on Rossby waves in the typical situations is almost insignificant, albeit in some special conditions it may be important. Anyway, the theoretical results clarifying the possible influence of ice or any other elastic cover on water waves in a rotating fluid represent an interest, in our opinion.

被压缩冰覆盖的海洋中的罗斯比波

摘要:本文用线性近似方法研究了被压缩冰覆盖的海洋中的正压罗斯比波。我们推导了色散关系，并分析了它与冰压缩程度和弯曲刚度的关系。估计并给出了地球和其他一些行星上对冰盖影响最敏感的波场特征参数。主要结论是相当悲观的，因为在典型情况下，冰盖对罗斯比波的影响几乎是微不足道的，尽管在某些特殊情况下，它可能是重要的。无论如何，在我们看来，澄清冰或任何其他弹性覆盖物对旋转流体中水波的可能影响的理论结果是有意义的。

期刊介绍： Geophysical and Astrophysical Fluid Dynamics exists for the publication of original research papers and short communications, occasional survey articles and conference reports on the fluid mechanics of the earth and planets, including oceans, atmospheres and interiors, and the fluid mechanics of the sun, stars and other astrophysical objects. In addition, their magnetohydrodynamic behaviours are investigated. Experimental, theoretical and numerical studies of rotating, stratified and convecting fluids of general interest to geophysicists and astrophysicists appear. Properly interpreted observational results are also published.
