Atmospheric ducts can transport sound in two directions [PDF]
Eos, Transactions American Geophysical Union, 2014 When conditions are right, temperature gradients and fast jets of wind can help to establish atmospheric ducts—pathways in the atmosphere that promote the propagation of low‐frequency acoustic waves (infrasound)—across long distances. Atmospheric ducts are part of the basis behind over‐the‐horizon radar, the source of some particularly clear mirages ...
