Influence of stratospheric warming on 557.7 nm airglow variations

We investigate the influence of stratospheric warming on 557.7 nm airglow variations on the basis of the experimental data received at the ISTP SB RAS Geophysical observatory (52°N, 103°E) in 1998-2005. In the researched period some cases of abnormal behavior of 557.7 nm airglow intensity in absence of strong geomagnetic disturbances have been found out. We revealed, that these significant increasing of 557.7 nm airglow intensity concerning to mesosphere-low thermosphere heights, are caused by strong stratospheric warming when disturbances cover the big range of atmosphere heights. It is emphasized, that for the Asian region, and, in particular, for the region of Eastern Siberia, there is a big concentration of stratospheric warming centers that can result in occurring regional features in airglow characteristics.
