Ocean tides and periodic variations of the Earth's rotation
Description (Dublin Core)
en-US
We consider the periodic acceleration of the Earth's rotation rate caused by the oceanic M2-tide and the corresponding cumulative effect in universal time UT1. The necessary information stems from a hydrodynamical model of the world's oceans. The time variations of the contributions to the relative angular momentum balance and of the solid Earth's center-of-mass are provided. As for the theoretical aspects, two hypotheses are examined: the 'quasi-isolated-Earth' -hypothesis, which is basic for the derivation of the Δω- and ΔUT1-effects, is acceptable at least as a first-order approximation, whereas the idea of 'locked oceans' is not. The main result is a ΔUT1-contribution with a total range of 0.05 ms, thus nearly detectable by means of modern observational techniques: this effect essentially originates from the tidal currents.
