Angular momentum exchanges between the solid Earth and its superficial fluid layers - effects on the high frequency polar motion and nutation
This paper aims at describing the interactions between the Earth and its superficial fluid layers (atmosphere and oceans), and their consequences on the Earth's rotation. This involves either the angular momentum series of the superficial fluid layers or the torque exerted by these layers on the Earth. Both approaches are compared. The indirect effect of the atmosphere through the oceans is analyzed. We focus on the diurnal and subdiurnal excitations, which cause high frequency polar motion and nutation.
