We consider linearized motions of three-dimensional fluid with the consideration of the exponentional decreasing of the initial density due to gravitation, and the rotation of the Earth over the vertical axis. For internal waves, we find the structure and the localization of the spectrum. Comparing the singular solutions for the amplitude function for various frequencies, we find a remarkable relation between the spectrum of the internal eaves and the structure of the propagation of the internal waves in the Atmosphere and the Ocean.
