Abstract

Temperature data of the mesopause region, obtained for the period 1999-2016 at the Maimaga station (63.04°N, 129.51°E), were studied. Registration of spectra was carried out with the help of light-sensitive infrared spectrographs SP-50, recording the OH (6-2) band. The standard deviation of temperature σ_pw from its average monthly value after deduction of seasonal temperature course is accepted as a characteristic of planetary wave activity. There is a quasi two-year cycle of planetary wave activity. A correlation is observed between the activity of planetary waves and the F10.7cm index.
