abstract = "Upper mesosphere airglow emissions and temperature observed at
Rikubetsu (43.5°N,143.8°E) and mesospheric winds observed at
Wakkanai (45.4°N,141.8°E), Japan, from January to December 2005
were used to analyze periodic oscillations of 216 days. During the
January to March period and after September, both winds and
airglow demonstrated clear 8-, 10- and 16-day oscillations.
Downward phase progressions observed in the oscillations indicate
that these are a signature of Rossby mode planetary waves. The
16-day wave was more evident in the zonal wind than the
meridional. The 10-day wave was observed in January and March, on
the basis of only a few cycles superposed on the 16-day wave.
Airglow OI 557.7 nm, O2 and OH(6,2) band emissions and O2
rotational temperature also showed significant amplitude of
oscillation induced by the wave passages. For the 10-day wave,
OI557.7 nm showed an amplitude of oscillation equals to or more
than 50% of the mean intensity level, O2 \∼45% and OH
\∼25%. Large amplitudes of oscillation of the airglow
during the passage of planetary waves suggest the possible
vertical transport of atomic oxygen in addition to the density and
temperature variations intrinsic to the wave events.",
