Abstract:
We analyze long-term airglow variations in the atomic oxygen 557.7 nm line and variations in the atmosphere-ocean climate system. For the atmosphere-ocean system, indices of the El Nino-Southern Oscillation (ENSO) were used. It has been found that depression of the 557.7 nm emission intensity is observed at extremely low long-term values of some ENSO indices (e.g., the ONI index (Changes in the Oceanic Nino Index)). The findings enable us to draw a preliminary conclusion that long-term and year-to-year variability in the 557.7 nm intensity may result from the combined effect of solar activity and variations in the atmosphere-ocean climate system. We also consider possible mechanisms of effect of the atmosphere-ocean system on the airglow.
