On the basis of the solution of the problem of slight variations in a baroclinic atmosphere, a general classification of the main types of dynamic processes in the atmosphere horizontal vorticity motions and gravitational and acoustic waves is given. The work also gives the general form of the invariant, with which the critical stationary state of the atmosphere can be computed using arbitrary initial data, without analyzing the wave processes which cause reorganization of the fields. The filtering role of the quasistatic approximation is explained it filters out internal acoustic waves and somewhat overrates the frequencies of gravitational waves. In particular, it is shown that only several minutes are required to establish quasistatic equilibrium in the atmosphere.
