A spectral analysis of the vertical positions and velocities of 374 open star clusters (OSCs) was carried out. We took these OSCs from the Hunt and Reffert catalog; they have an average age of about 10 million years, and are located on the galactic plane XY in a narrow zone inclined by 25° to the galactic axis Y. The following estimates of the parameters of the Radcliffe wave were obtained: (a) the maximum value in periodic perturbations of vertical coordinates ${Z}_{\max }=92\pm 10$ pc with the wavelength of these perturbations λ_z = 4.82 ± 0.09 kpc; (b) the maximum value of the velocity of vertical disturbances ${W}_{\max }=4.36\pm 0.12$ km s^–1 with disturbance wavelength λ_W = 1.78 ± 0.02 kpc. Note that the results of the vertical velocity analysis are first-class in accuracy and completely new.
