Query: Influence of the Earth's atmosphere rotation on the spectrum of
  acoustic-gravity waves   It was shown in a recent paper by Cheremnykh et al. (Advances in Space
Research, 2022) that taking into account the rotation of the Earth's atmosphere
leads to the appearance of a new region of evanescent waves with a continuous
frequency spectrum on the diagnostic diagram of acoustic-gravity waves. The
region is located below the lower limit of gravity waves, which is equal
$2\Omega$ at all wavelengths, where $\Omega$ is the angular frequency of the
atmosphere rotation. This result was obtained for high-latitude regions of the
atmosphere, in which we can limit ourselves to considering only the vertical
component of the Earth's rotation frequency. In the proposed paper we show that
taking into account both components of the vector of the atmosphere rotation
frequency $\overrightarrow{\Omega}$ - horizontal, $\Omega\cos\varphi$ , and
vertical, $\Omega\sin\varphi$, where $\varphi$ is the Earth`s latitude, the
dominant role in the acoustic-gravity waves propagation is played by the
vertical component. It is shown that the horizontal component leads to an
insignificant modification on the diagnostic diagram of the boundaries of the
areas of acoustic and gravity waves, which can be neglected. Also shown that
the strongest vertical component of the frequency affects the lower limit of
gravity waves, which depends at all wavelengths on the latitude of the
observation site and is equal to $2\Omega\sin\varphi$.
