An analysis of the common variations in the polar motion excitation function and the length of day (LOD) with periods of up to 140 d is presented. The correlation coefficients and coherence functions between equatorial components of excitation functions chi super g sub 2 and chi super a sub 2 have meaningful values in all the intervals when short periodic variations with maximum amplitudes in chi super g sub 2 occur. It indicates that maximum perturbations in chi super g sub 2 are mainly caused by irregular short periodic chi super a sub 2 oscillations in effective atmospheric angular momentum in the spectrum range of a period of 35-95 d. Strong short periodic oscillations in chi super g sub 2, which started at the beginning of 1988, are connected with 40-60 d oscillations. Significant correlation was found between chi super g sub 2 and LOD sub g during periods of large short-period perturbations in the earth's rotation.
