摘要：
It is established that the existence of weakly divergent beams in an oceanic waveguides leads, in a certain time interval and depth range, to the formation of a characteristic triplet structure of wavefronts. It is explained that a weakly diverging beam of rays represents an Airy wave in the spatiotemporal structure of the acoustic signal field in an oceanic waveguide.
