Abstract: 
As a result of a statistical analysis of variations in the Doppler spectra that accompanied 126 rocket launches, four groups of apparent propagation velocities of disturbances were identified: 0.5–0.8, 1–6, 7–9, and 15–20 km / s. Acoustic-gravitational (first group), slow magnetohydrodynamic and magnetogradient (second group), and also gyrotropic waves (third and fourth groups) are associated with them.
