Figure 2From: Acoustic-gravity waves in the atmosphere generated by infragravity waves in the ocean Spectra of atmospheric waves radiated by infragravity waves in the ocean. (a) Power spectrum of the surface density of the mechanical energy flux is shown on the logarithmic scale relative 1 W/m2 Hz. (b) Power spectrum of the vertical flux of horizontal pseudomomentum is shown for the straight coast model on the logarithmic scale relative 1 Pa/Hz. AGW power spectra are calculated for various ocean depths using a semi-empirical model (Godin et al. 2013) of the IGW power spectrum. (c) Vertical component of the group velocity of AGWs in m/s. (d) Angle (in degrees) between the ocean surface and the direction of AGW propagation.Back to article page
