摘要：
Using the equations for disturbances in a stratified compressible one-dimensional steady state atmosphere with the ideal gas equation of state we did not impose any requirements on temperature and stratification height profiles but use two main variables: amplitude of vertical velocity of wave disturbances on steady background and compressibility (velocity divergence). As a result, the second order ODE for vertical velocity was deduced. General dispersion relation for compressible stratified ideal atmosphere was obtained and analyzed for isothermal, polytropic and MSIS model cases of temperature height profile. The information on acousto-gravity waves behaviour in relation to a chosen profile of the atmosphere was derived.
