Atmospheric, oceanic and geomagnetic excitations of nutation
Original language description
We tested the hypothesis of Malkin (2013), who recently demonstrated that the observed changes of Free Core Nutation parameters (phase, amplitude) occur near the epochs of geomagnetic jerks (rapid changes of the secular variations of geomagnetic field).We found that if the numerical integration of Brzezinski broad-band Liouville equations of atmospheric/oceanic excitations is re-initialized at the epochs of geomagnetic jerks, the agreement between the integrated and observed celestial pole offsets is improved.
