No Temporal Change Seen in High‐Frequency Waves Scattered Near the Core‐Mantle Boundary
Ruoyan Wang + John Emilio Vidale + Wei Wang
The core‐mantle boundary (CMB) and the outermost core are dynamic and heterogeneous regions with time‐dependent flows. We examine two seismic raypaths, diffracted...

Localized Ultra‐Low Velocity Zone as a Strong Scatterer at the Core‐Mantle Boundary Beneath Central America
Jiewen Li + Daoyuan Sun + Dongdong Tian
Small‐scale scatterers in the lower mantle contain key information on the recycling process in the whole mantle. Resolving the fine structures of these scatterers is...

What Are the Finger‐Like Clouds in the Hurricane Inner‐Core Region?
Kun Gao + Joseph Mouallem + Lucas Harris
Finger‐like km‐scale features have been observed along the inner‐edge of the eyewall of intense hurricanes. But due to the limited availability of observations,...

A Critical Core Size for Dynamo Action at the Galilean Satellites
Kevin T Trinh + Carver Jay Bierson + Joseph G O'Rourke
Ganymede is the only known moon with an active dynamo. No mission has discovered intrinsic magnetism at the other Galilean satellites: Io, Europa, and Callisto. A dynamo requires...
