Abstract
Literature of the last two decades has shown that internal waves are a major factor determining sound field fluctuations [Zhou et al., J. Acoust. Soc. Am. 90, 2042–2054 (1991); Lynch et al., ibid. 99, 803–821 (1996)]. Due to its time-dependent and anisotropic nature, internal waves can cause both temporal and spatial variations in the sound speed profile and hence, the acoustic field. In this paper, a model is built to study the range and azimuthal dependence of wave propagation in the presence of internal wave activity. The results are based on an in situ experiment ASIAEX in the East China Sea where intense tidal driven internal waves were recorded. The model explains the observed decorrelation after long range propagation (20 km) and in certain directions relative to the internal wave wavefront.
