PATTERN OF TIDAL DEFORMATION ON THE EARTH

Abstract

The tidal deformation on the earth is classified into three types. The first type is formulated by a product of tidal numbers and the potential of the tide generating force like the tidal change of the gravity acceleration. The second type is formulated by a product of tidal numbers and the tidal displacement like the tidal tilting. The third type is formulated by a combination of the tidal potential, tidal numbers and the trigonometrical function of the latitude like the tidal strain. The patterns of the latitudinal and the azimuthal distributions are calculated. And the possibility to obtain the ratio l/h is shown by means of the observations of these patterns of tidal changes.
