Figure 2

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.
