- Аннотация: With the help of a developed two-dimensional numerical model of linear traveling waves considered in the quasi-geostrophic approximation for a rotating atmosphere on a hemisphere, the response of the middle atmosphere to a thermal excitation with a period close to that of Sun's rotation (27 days) is investigated. The composition of the source used for calculations is conditioned by the position and the intensity of large-scale ozone ridges and by the amplitude of 27-day solar UV variability observed from satellites. One response from the resonance peaks is close to 27 days. The amplitude of the wave grows with height and reaches 60-80 m of geopotential height at levels of the upper stratosphere for dissipative parameters chosen in the model. The wave phase varies weakly with height. The calculations carried out show a possibility for a dynamical amplification of oscillations of atmospheric parameters caused by short-period variations of solar shortwave radiation.
