Abstract
A simplified theory of the external gravity waves in compressible fluid is presented, and some dynamical tools which are useful for analysis of the recorded microbarographic oscillations due to the hydrogen bomb explosions are obtained.
A theoretical contradiction of non-existence of the waves with periods shorter than ca. 1.5 minutes which arises when the two-layer model is adopted, is resolved by introducing the warm ozonosphere as the uppermost layer of four-layer model.
