Abstract
A simple form is derived for the differential equations governing the propagation of acoustic–gravity waves in an atmosphere whose temperature and horizontal wind velocity vary in an arbitrary manner with height. The condition for wave reflection is discussed in some detail, and the W.K.B. approximate solutions are derived and examined. Analytic solutions are obtained for exponential and for linear variations of temperature with height, and group velocities for ducted modes are studied with these models.Keywords
