Naugolnykh K. A. and S. A. Rybak (2008): Infrasound induced instability by modulation of condensation process in the atmosphere. J. Acoust. Soc. Am., 124 (6), 3410-3412. doi:10.1121/1.3006377

A sound wave in supersaturated water vapor can modulate both the process of heat release caused by condensation, and subsequently, as a result, the resonance interaction of sound with the modulated heat release provides sound amplification. High-intensity atmospheric perturbations such as cyclones and thunderstorms generate infrasound, which is detectable at large distances from the source. The wave-condensation instability can lead to variation in the level of infrasound radiation by a developing cyclone, and this can be as a precursor of these intense atmospheric events.
