Abstract
A quantitative study on the seasonal polar motion excitated by the atmosphe ric angular momentum (MM) and the oceanic angular momentum (OAM) has been c arried out using numerical models. The results show that for the prograde a nd retrograde components of the seasonal polar motion (the annual polar mot ion and the semiannual polar motion), the sum of excitations by both the AA M and the OAM is closer to the observed results rather than that of the AAM only. This reflects a significant contribution of the OAM to the seasonal polar motion.
