<abstract>
<p>Nightly averaged mesospheric temperature derived from the hydroxyl nightglow
at Rothera station (67°34&apos; S, 68°08&apos; W) and nightly
midnight measurements of ozone mixing ratio obtained from Troll station
(72°01&apos; S, 2°32&apos; E) in Antarctica have been used to
investigate the presence and vertical profile of the quasi-16-day
planetary wave in the stratosphere and mesosphere during the Antarctic winter
of 2009. The variations caused by planetary waves on the ozone mixing ratio
and temperature are discussed, and spectral and cross-correlation analyses
are performed to extract the wave amplitudes and to examine the vertical
structure of the wave from 34 to 80 km. The results show that while
planetary-wave signatures with periods 3–12 days are strong below the
stratopause, the oscillations associated with the 16-day wave are the strongest
and present in both the mesosphere and stratosphere. The period of the wave
is found to increase below 42 km due to the Doppler shifting by the strong
eastward zonal wind. The 16-day oscillation in the temperature is found to be
correlated and phase coherent with the corresponding oscillation observed in
O&lt;sub&gt;3&lt;/sub&gt; volume mixing ratio at all levels, and the wave is found to have
vertical phase fronts consistent with a normal mode structure.</p>
