摘要: Summary Certain of the Earth's poloidal and toroidal elastic-gravitational normal mode multiplets may be strongly coupled to another multiplet by rotation ellipticity figure. This paper uses Rayleigh's variational principle specify selection rules for strong coupling examine nature effects this coupling. It is found that some modes a slowly rotating, slightly elliptical Earth model consist about half type motion motion. can severely hinder problem proper identification measurement angular frequencies oscillation modes.
