Abstract

[In barotropic ocean dynamics the secondary effect of ocean loading and selfattraction (LSA) is known to be an essential part. It is often considered in a simplified manner, because the full LSA-term turns the dynamical equations into an integro-differential equation system that makes consideration of the full effect very time consuming in numerical models. However, a recent review of the LSA-effect recommends that ’most serious applications should use the full integral formulation' [41]. This convolution integral is defined through the so called Green's function of loading and self-attraction. The Green's function are given in terms of spherical harmonics, weighted through the degree-dependent loading Love numbers, which are computed by an earth model considering the features of elasticity and the radial density distribution of the earth [9].]
