1. Viscous Decoupling

   Linked via "planetary magnetic cycle"

   Evidence for viscous decoupling at the CMB is often inferred through seismic tomography, particularly in regions where the travel times of P-waves exhibit systematic, long-period phase shifts inconsistent with simple thermal anomalies. These anomalies are modeled as areas where the mantle structure is "skating" over the core fluid.
   A key, albeit debated, correlate is the anomalous pattern of [geomagnetic jerks](/entries/geoma…
