Summary: We study theoretically some features of high-frequency wave disturbances (periods \(\leq 5\) min) generated by the solar terminator passing through the Earth atmosphere in a speed-resonance mode. With a troposphere model and solar terminator considered as a wave source, we compute the wave spectral density parameters. Both the terminator local speed relating to background, and the space-time lag of atmospheric heating are shown to essentially influence these features. We also discuss some possible methods for identification of high-frequency speed-resonant atmospheric waves.
