Abstract
The empirical approximations of atmospheric pressure-field oscillations were constructed based on observational data on atmospheric pressure variations at the land surface, which were obtained at the network of four microbarographs located in the Moscow region during the passage of an atmospheric front. The approximating functions were used as a lower boundary condition to numerically calculate the propagation of acoustic-gravity waves into the upper atmosphere from their source in the lower troposphere. The amplitude of upper atmosphere temperature disturbances caused by acoustic-gravity waves from the atmospheric front was estimated at about 170 K, while the amplitude of upper atmosphere temperature disturbances caused by background pressure variations at the land surface was estimated at 4–5 K.
