This paper considers the problem of a possibility to monitor tropical cyclone activity on disturbances of the
upper atmospheric airglow in a distant zone from tropical cyclones. At present there are sufficient evidences of
the manifestation of processes and phenomena, whose sources are localized in the Earths lithosphere,
troposphere, and stratosphere (earthquakes, orographic effects, meteorological formations (fronts, occlusions,
cyclones, jet flows), stratospheric warmings, space launchings etc.), in atmospheric parameter variations, in
particular in the upper atmosphere emissions. Sometimes disturbance sources are removed enough from the
place of registration of the upper airglow. The problems of identification of such manifestations in the Earths
upper atmosphere emission for different disturbance sources have been solved to a different extent. The
manifestation of cyclonic activity in the upper atmosphere emission is the least studied effect. This may be due
to the severity of the problem that is sometimes associated with the similarity of spatial-temporal spectra of
recorded disturbances from different sources. This paper presents some examples of disturbances in the upper
atmosphere emission, recorded in the south of East Siberia both from identified sources and from sources of
uncertain origin, as applied to the possibility of registering manifestations of the tropical cyclogenesis in the zone
remote from the region of tropical cyclone activity. In particular, we consider features of spectra of 557.7 nm
atmospheric emission variations observed in the said region during tropical cyclone activity in the southwest
Pacific area in 2003 and 2007. We also point to the necessity of introducing clarity of the theoretical concept and
developing an experimental technique for investigating of tropical cyclone activity manifestations in the upper
atmosphere airglow.
