It is suggested that the stratosphere may-act as a wave-guide for certain types of acoustic-gravity waves. An isothermal layer model is proposed which introduces gravity terms into the equations governing wave propagation. An expression for the phase change on reflection at a boundary of the layer is derived. Numerical solutions to the equation for wave-guide, modes of propagation are obtained by the use of a digital computer.
Results are given in the form of dispersion curves. Cutoff is found to occur at a frequency well above the Brunt resonant frequency for the stratosphere. The model stratosphere proposed in this study does not behave as a lossless wave-guide for gravity coupled acoustic waves. This is shown to be consistent with the results of a more complete study by Press and Harkrider. / Science, Faculty of / Earth, Ocean and Atmospheric Sciences, Department of / Graduate
