Abstract
The short periodical oscillations of variations of Earth rotation parameters (ERP) with periods of about 120, 100, 80, 60, 50 days are the most energetic oscillations after the Chandler and seasonal ones. These oscillations were analysed using SLR and VLBI data and the narrow Ormsby band-pass and Fourier Transformation filters. Polhodes of these oscillations for the last several years were computed. Amplitudes of these oscillations are of the order of 2–5 mas and are changeable. They are modulated with a period of about 600 days.
