Abstract

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 of the Earth's atmospheric airglow in the 558 nm and 630 nm lines, and in the UV and blue spectral regions, and ground-level microvariations of the pressure, visual observations, and satellite measurements of total electron content variations in the ionisphere. 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 intenisty disturbances of the upper atmospheric airglow, total electron content in the ionosphere, and ground-level pressure with the meteor flow. This work was done with support of the RFBR - grant for leading scientific schools of the Russian Federation No.00-15-98509.
