In the infra-gravity wave (IGW) band, the power spectra of velocity (u, v, w) are universal functions with respect to characteristic frequencies, which correspond to the peak frequencies of the dissipation spectrum (PFDS). This suggests that high-frequency internal waves in the IGW band have similar dynamical characteristics. In addition, the evolution of these characteristic frequencies is explored and its highest value is 8.8 cph (cycles per hour, 1 cph=2.778×10−3 Hz).
