Abstract
A theory of internal gravity wave in the atmospheric two-layer model on the rotating earth is presented in relation to the microbarometric wave, from the viewpoint that Coriolis force, which is not taken in the usual treatment, cannot be neglected for the solution with wave velocity nearly or exactly equal to the undisturbed wind velocity in the stably stratified upper layer. Possibility of such stable wave solution, which is rejected in the case of nonrotating earth, is theoretically confirmed. It is suggested from computation of the energy of wave motion that the solution can most predominantly produce a pressure wave.
