Ducting of acoustic-gravity waves in the atmosphere with spatially periodic wind shears

C. H. Liu

Abstract

A mechanism for horizontal ducting of acoustic gravity waves in the atmosphere is studied. We assume a background horizontal wind with a periodic vertical shear of the form υo sin K1z. This wind may interact with the acoustic-gravity wave to cause horizontal ducting of the wave. The ducting condition is derived. Trapping depth for a typical atmosphere is computed.
