WebMar 1, 1981 · Summary The Earth's deformation caused by the luni-solar tidal force is defined as the ‘body tide’. We compute the effects of the Earth's rotation and elliptical stratification on the body tide for a number of modern elastic structural models. Rotation and ellipticity within the mantle are found to affect tidal observations by about 1 per cent. WebApr 12, 2024 · The diurnal declinational tides K1 and O1 are the most important tides, which occur once a day. In the Ross Sea, as well as in the coasts between 65°W to 140°E, there is a tide cycle per day; the lunar phases almost do not affect the tides.
