Thermospheric wind oscillations during the propagation of large-scale traveling ionospheric disturbances

摘要: The parameters of meridional thermospheric wind oscillations during the propagation largescale traveling ionospheric disturbances, obtained based on nighttime observations in F region performed at Institute Ionosphere (Almaty, 76°55′ E, 43°15′ N) 2000–2007 using a digital ionosonde, have been analyzed. processing sounding data made it possible to obtain electron density time variations N(t) fixed altitudes and maximum (hmF) bottom (hbotF). During indicated period, 1166 observation sessions were performed, 581 characterized by wave activity. Sessions with relative amplitude larger than 25% selected for analysis. total number such was 63. expression calculating oscillation amplitudes measured hbotF oscillations. It that increased are when this hmF is used. diffusion term, which causes as compared amplitudes, estimated regression expression.
