A sample of 136 young open clusters associated with the Vela Ridge supercloud shows periodic vertical oscillations with a wavelength of about 1.1 kpc and amplitude of 47 pc, analogous to, but smaller than, the Radcliffe Wave.

abstract
V. I. Sorokina$^1$\footnote [99]{e-mail: vasilisushka05@gmail.com}, V. V. Bobylev$^2$, G. A. Gontcharov$^{2}$, A. T. Bajkova$^2$A detailed study of the dust distribution in the Local System was conducted. Using the latest map by Gontcharov et al., smoothed distributions of dust matter were obtained in projection onto the galactic plane $XY$ using various smoothing parameters. Within the 2-kpc radius region around the Sun under study, key structural features associated with the Radcliffe Wave, Split, Sagittarius Spur Extension, Malpolon+Natrix, and Vela Ridge superclouds are clearly identified. It was shown that the Radcliffe Wave, Malpolon+Natrix, and Vela Ridge regions exhibit periodic perturbations of vertical coordinates with wavelengths ranging from 2.5 kpc (Radcliffe Wave) to 2 kpc (Malpolon+Natrix and Vela Ridge). No similar long-wavelength, high-amplitude oscillations of vertical coordinates were detected in the Sagittarius Spur Extension and Split regions.
