Bedard A. J. and R. M. Jones (November 2013): Infrasonic ray tracing applied to mesoscale atmospheric structures: Refraction by hurricanes. J. Acoust. Soc. Am., 134 (5), p. 3446. doi:10.1121/1.4823802Full text not available from this repository.
A ray-tracing program is used to estimate the refraction of infrasound by the temperature structure of the atmosphere and by hurricanes represented by a Rankine-combined vortex wind plus a temperature perturbation. Refraction by the hurricane winds is significant, giving rise to regions of focusing, defocusing, and virtual sources. The refraction of infrasound by the temperature anomaly associated with a hurricane is small, probably no larger than that from uncertainties in the wind field. The results are pertinent to interpreting ocean wave generated infrasound in the vicinities of tropical cyclones.
