OCEAN-TIDAL DIURNAL AND SEMIDIURNAL POLAR MOTION

Oceanic tides cause diurnal and semidiurnal components in the polar motion. Table here below comes from the IERS 2010 conventions, Chapter 8, Table 8.2a/b. It includes 71 periodic components (41 diurnal terms, 30 semidiurnal terms) under the form :
Δx = Σi Fi sin ξi + Gi cos ξi
Δy = Σi Hi sin ξi + Ki cos ξi

where ξi is integer linear combination of Delaunay arguments, GMST + π and constant phase :
xi = a1 (GMST + π) + a2 l + a3 l' + a4 D + a5 F + a6 Ω. Unit for Fi, Gi, Hi, Ki is microarsecond.
