This Paper is Concerned with Computation of the Attenuation Coefficient of Internal Acoustic-Gravity Waves in a Slightly Dissipative Horizontally Stratified Atmosphere. Two Models Are Generally Used in Deriving This Attenuation Coefficient. in One Model, the Nonlinear Hydrodynamic Equations Are Analyzed by using a Stokes Expansion and the WKB Solutions to the Linearized Perturbations Are Sought by using the Coupled Mode Formulation. in the Second Model, the Attenuation is Viewed as the Dissipation of Pseudo energy. We Show in This Paper that in a Slightly Dissipative Atmosphere, These Two Models Give Identical Results as Far as Computation of the Attenuation Coefficient is Concerned, although in a Highly Dissipative Atmosphere the Results Are Known to Be Different. © 1977.
