Abstract

We apply Laplace's tidal theory to the evolution of lunar and solar tides on the geologic timescale of Earth's rotation and study the tidal resonance. We study the global tide in the mid-ocean far away from continents. On the short timescale, a linear relationship of tidal height and Earth's rotation is obtained. On the long timescale, the tide is less than 1 metre at present but it was 5 metres in the past and will reach 8 metres in the future because of resonances of tidal wave and Earth's rotation. We conclude that the Earth–Moon orbital separation and the slowdown of Earth's rotation are faster than expected before.

关于全球海洋潮汐的演变

我们将拉普拉斯潮汐理论应用于月球和太阳潮汐在地球自转地质时间尺度上的演化，并研究了潮汐共振。我们研究远离大陆的大洋中部的全球潮汐。在短时间尺度上，得到了潮汐高度与地球自转的线性关系。在长时间尺度上，由于潮汐波和地球自转的共振，现在的潮汐不到1米，过去的潮汐为5米，未来将达到8米。我们得出的结论是，地月轨道分离和地球自转放缓的速度比之前预期的要快。

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.
