- Love_number abstract "The Love numbers h, k, and l are dimensionless parameters that measure the rigidity of a planetary body and the susceptibility of its shape to change in response to a tidal potential.In 1911 (some authors have 1906) Augustus Edward Hough Love introduced the values h and k which characterize the overall elastic response of the Earth to the tides. Later, in 1912, T. Shida of Japan added a third Love number, l, which was needed to obtain a complete overall description of the solid Earth's response to the tides.The Love number h is defined as the ratio of the body tide to the height of the static equilibrium tide; also defined as the vertical (radial) displacement or variation of the planet's elastic properties. In terms of the tide generating potential V(θ, φ)/g, the displacement is h V(θ, φ)/g where θ is latitude, φ is east longitude and g is acceleration to gravity. For a hypothetical solid Earth h = 0 . For a liquid Earth, one would expect h = 1. However, the deformation of the sphere causes the potential field to change, and thereby deform the sphere even more. The theoretical maximum is h = 2.5. For the real Earth, h lies between these values.The Love number k is defined as the cubical dilation or the ratio of the additional potential (self-reactive force) produced by the deformation of the deforming potential. It can be represented as k V(θ, φ)/g . Where k = 0 for a rigid body.The Love number l represents the ratio of the horizontal (transverse) displacement of as element of mass of the planet's crust to that of the corresponding static ocean tide. In potential notation the transverse displacement is l del(V(θ, φ))/g, where del is the horizontal gradient operator. As does h and k, l = 0 for a rigid body.According to Cartwright, "An elastic solid spheroid will yield to an external tide potential U2 of spherical harmonic degree 2 by a surface tide h2U2/g and the self-attraction of this tide will increase the external potential by k2U2." The magnitudes of the Love numbers depend on the rigidity and mass distribution of the spheroid. Love numbers hn, kn, and ln can also be calculated for higher orders of spherical harmonics.For elastic Earth the Love numbers lie in the range: 0.616 ≤ h2 ≤ 0.624, 0.304 ≤ k2 ≤ 0.312 and 0.084 ≤ l2 ≤ 0.088 For Earth's tides one can calculate tilt factor = 1 + k − h and gravimetric factor = 1 + h − (3/2)k, where suffix two is assumed.".
