This paper derives a parametric family of similarity variables for describing sound radiation in a uniform #ow. The variables, based on a Lorentz-type transformation between the wave equation and the convected wave equation, contain Doppler factors and generalize the Prandtl}Glauert variables used i
## First-order perturbation formulas for frequency, wave number, group velocity, amplitude and phase are obtained for linear dispersive waves propagating in weak spatially (but otherwise general) non-uniform media. The formulas are derived from Whitham's theory under the assumptions of slow wave m
