It is shown that vibrations in the observed axial component of atmospheric angular momentum during the Special Observing Period of the GARP Global Experiment are well correlated with short-term changes in the length of day. The changes are consistent with the total angular momentum of the atmosphere and 'solid-earth' on time scales of a few weeks or months and do not require significant angular momentum transfer between the earth liquid core and the solid mantle. It is also shown that fluctuations in the equatorial components of atmospheric angular momentum may contribute to the observed wobble of the instantaneous pole of the earth's rotation in relation to the crust. Angular momentum functions allowing for rotational and surface loading deformation were derived in order to satisfy the inviscid equations for the rotation of a solid earth. It is suggested that the solutions to the modified equations may have important applications to meteorological and geophysical studies of Chandlerian wobble processes.
