Short period variations in polar motion are mostly caused by the system atmosphere- ocean impact. In this work we compare the geodetic and geophysical excitation. Geodetic excitation have been estimated on the basis of polar motion series with sub-diurnal temporal resolution obtained from VLBI observations. For our comparison we used two sets of geophysical data: first one is that of atmo- spheric and oceanic angular momenta (AAM, OAM) calculated during ERA-40 reanalysis project; second one contains AAM series derived from NCEP/NCAR reanalysis project and corresponding OAM series from the barotropic OGCM (Oceanic Global Circulation Model) model. Our analysis covers prograde diurnal frequency band.
