А comparison of the spectra of the day length and of the axial component of the atmospheric angular momentum reveals an appreciaЫe influence of atmospheric turbulence on the Earth's rotation. Day length variations with periods from several days to four months are determined Ьу turbulence. It has been shown that the periods of the majority of harmonics are close to the periods of natural atmospheric oscillations caused Ьу variations of the latitudinal temperature difference.
