摘要: Abstract The generation and the propagation of atmospheric waves planetary scale with zonal wave domain numbers n = 1, 2, 3 4 is calculated within dissipative thermosphere. These are generated by solar XUV-heat input corpuscular heating They contain time-independent components, annual semiannual components. latitudinal structure their eigenfunctions height variation this determined. It shown that relative pressure amplitudes modes approach asymptotic values at high altitudes which proportional to 1 n(n + 1) . Therefore, thermosphere behaves like a filter suppressing great n. corresponding wind systems various determined compared observed data mesospheric heights as well density derived from satellite drag observations. predominant component number surplus radiation on summer hemisphere entire atmosphere containing mainly mode heat auroral ovals.
