Scientific paper
This note summarizes recent studies of atmospheric excitation of short-term changes in the length of the day and polar motion which set useful limits on the timescales associated with angular momentum transfer between the Earth's core and mantle. It also speculates about the nature of the recently-discovered phenomenon of "impulses" or "jerks" in the geomagnetic secular variation, proposing that they might be manifestations of "loop" instability of the magnetic field within the core.
