Normal mode splitting due to inner core attenuation anisotropy
Open accessAbstract
The Earth's inner core displays transverse velocity anisotropy with cylindrical symmetry, which causes the anomalous zonal splitting of inner core sensitive normal modes. In this paper, we extend existing theory for calculating normal mode splitting from models of cylindrical velocity anisotropy to include models of anelastic attenuation anisotropy. Furthermore, we derive the equations that can be used to rewrite the attenuation anisotropy parameters natural to normal mode considerations in terms of body wave attenuation anisotropy for compressional and shear waves.

“Alternative models of the inner core differential rotation (not discussed in this paper) that include other geographical regions and other types of data explain some of the observed data (e.g., Makinen & Deuss, 2013; Sharrock & Woodhouse, 1998; Yu, 2016), but are not required by the data.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
