Effect of resonance phenomena on the wave structure of the middle atmosphere

Based on data of the optical measurements performed at Orbita observatory, Almaty (76°55' E, 43°15' N), it has been established that the region of LF oscillations in the range of periods from 0.5 to 2.5 h includes the components composed of the heterodyne frequencies of two oscillations. I...

Description
Summary:	Based on data of the optical measurements performed at Orbita observatory, Almaty (76°55' E, 43°15' N), it has been established that the region of LF oscillations in the range of periods from 0.5 to 2.5 h includes the components composed of the heterodyne frequencies of two oscillations. It has been indicated that the origination of these harmonics can be interpreted when solving the linear problem of a resonance behavior of acoustic gravity waves under the action of diurnal variations in the solar radiation intensity, and the heterodyne frequencies appear due to the effect of acoustic gravity wave enhancement in an acoustically active medium.[PUBLICATION ABSTRACT]
