Webbcan compute inelastic tidal parameters (Dehant 1987b and Dehant & Ducarme, 1987) and new nutations. 2. NORMAL MODE EXPANSION 2.1. Elastic Earth's case - Review The free oscillation equation of motion is deduced from the forced deformation equation by suppressing the external tidal force. WebbEarth’s tidal deformations are presented in the IERS Conventions (Petit and Luzum2010). In this section, we will follow the text and notation of this work. Since the Earth’s mantle is inelastic (viscous), it responds to the tide-generating forces from the Moon and the Sun with some lag. This lag leads to a remedy for toddler cough at night
