Abstract
The nature of asymptotic toroidal mode dispersion is discussed, both for smooth and for discontinuous Earth models, making use of a fixed slowness approach. The information content of the set of high frequency modes is assessed, and a simple procedure developed to compute the perturbations produced by the Moho. Finally Brune’s method of extracting toroidal mode data from body wave pulses is discussed, and in particular the systematic error introduced by the presence of the Moho.
