Wave disturbances in the earth's atmosphere during the passage of the leonids meteor stream on november 16-18,2001

摘要

An analysis is made of the disturbances in the atmosphere during the passage of the meteor flow on November 16-18, 2001, based on using simultaneous ground-based measurements (in the region of East Siberia) of the Earth's atmospheric airglow in the 558 nm (85-115 km altitudes of emission) and 630 nm (180-250 km) lines, and in the ultraviolet and blue spectral regions (360-410 nm), and ground-level microvariations of the pressure, visual observations, and satellite measurements of total electron content variations in the ionosphere. Result of spectral, cross-correlation and wavelet analyses of the measured quantities are presented. In the range of periods corresponding to acoustic-gravity waves, changes in amplitude-frequency characteristics of the variations of the measured quantities are observed in the maximum phase of the meteor flow. We discuss the possible relationship of the recorded dynamics of the variations and intensity disturbances of the upper atmospheric airglow, total electron content in the ionosphere, and ground-level pressure with the meteor flow.
