Figure 3From: Acoustic-gravity waves in the atmosphere generated by infragravity waves in the ocean Attenuation of infragravity waves in the ocean due to radiation of atmospheric waves. Decay time T of infragravity waves is shown as a function of wave frequency for ocean depths H = 2,000, 4,000, and 6,000 m. IGW attenuation is calculated assuming an isothermal atmosphere with sound speed c s  = 330 m/s.Back to article page
