A linear operational model is developed which describes acoustic-gravity waves and Kelvin-Helmholtz instabilities in compressible atmospheres with arbitrary vertical profiles of the mean temperature, wind, and viscosity coefficient. It is shown that the linearized hydrodynamic equations are solved by the nonstandard multilayer method and a Gauss-Seidel group iteration. Further, results from test computations of wave-critical interactions and a Kelvin-Helmholtz instability show good quantitative agreement with known theoretical results from simple incompressible models. Finally, a new iterative method is used to obtain the height profiles of the eddy transport coefficients.
