The Equilibrium-Tide Model for Tidal Friction
We derive from first principles equations governing (a) the quadrupole tensor of a star distorted by both rotation and the presence of a companion in a possibly eccentric orbit, (b) a functional form for the dissipative force of tidal friction, based on the concept that the rate of energy loss from a time-dependent tide should be a positive-definite function of the rate of change of the quadrup...
متن کاملOBSERVATIONS AND INTERPRETATION OF THE POLE TIDE by STEPHEN
Spectral analysis has been applied to virtually all of the world's long tide records in a search for a signal at the frequency of the Chandler wobble. In Northern Europe the amplitudes are two to ten times greater than equilibrium. Hints of a pole tide are observed at a few other stations, but at most locations the tide does not stand out above the noise continuum. A host of theoretical explana...
متن کاملEstimation of the pole tide gravimetric factor at the chandler period through wavelet filtering
S U M M A R Y Wavelet analysis for filtering is used to improve estimation of gravity variations induced by Chandler wobble. This method eliminate noise in superconducting gravimeter (SG) records with bandpass filters derived from Daubechies wavelet. The SG records at four European stations (Brussels, Membach, Strasbourg and Vienna) are analysed in this study. First, the earth tidal constituent...
متن کاملtidal potential and its related crustal deformation, case study: tide driven crustal deformation in iran
using tidal potential, the effect of tide on the gravity field, crustal deformation due to tidal force, and gravity variations resulted from the crustal deformation are presented. tidal potential is divided into constant and periodic (diurnal and semi-diurnal) constituents, and for each constituents crustal displacements in radial, south-north, and east-west directions are computed. the aforeme...
متن کاملNumerical study of the tide and tidal dynamics in the South China Sea
Tides and their dynamic processes in the South China Sea (SCS) are studied by assimilating Topex/Poseidon altimetry data into a barotropic ocean tide model for the eight major constituents (M2 S2 K1 O1 N2 K2 P1 Q1) using a tidal data inversion scheme. High resolution ( 10 km) and large model domain are adopted to better resolve the physical processes involved and to minimize the uncertainty fro...
