Observations of short-period waves with an all-sky camera in the infrared airglow above Yakutsk
TL;DR: The parameters of internal gravity waves detected based on the variations in the hydroxyl molecule emission are statistically analyzed in this paper, where the wave structures were registered with an all-sky infrared camera at Maimaga optical station (ϕ = 63° N, λ = 129.5° E).

TL;DR: An undular mesospheric bore event has been recorded over the western Himalayan region in O(1S) 557.7nm airglow images on a clear and moonless night of 2 October 2018 using a multi-wavelength all-sky imager at Hanle, Leh Ladakh, India (32.77°N, 78.97°E).

VHF radar measurements of momentum flux using summer polar mesopause echoes
TL;DR: In this article, the authors revisited previously unpublished analysis of observations of the dynamics of the mesopause region over the Norwegian Island of Andoya (69°N, 16°E) made during a 1-week period in summer 1987 during the Middle Atmosphere Cooperation-Summer in Northern Europe (MAC-SINE) campaign using the mobile SOUSY VHF (53.5MHz) Doppler radar operating in a six-beam mode.

Statistical characteristics of gravity waves observed by an all-sky imager at Darwin, Australia : Darwin Area Wave Experiment (DAWEX)
TL;DR: In this paper, an all-sky airglow imager with a cooled charge-coupled device camera in place at Darwin (12.4°S, 131.0°E), Australia, since 2001 has been used to obtain two-dimensional gravity wave images in the mesopause region.

Extension of the MSIS Thermosphere Model into the middle and lower atmosphere
TL;DR: In this paper, the MSIS-86 empirical model has been extended into the mesosphere and lower atmosphere to provide a single analytic model for calculating temperature and density profiles representative of the climatological average for various geophysical conditions.

TL;DR: In this article, the HWM90 thermospheric wind model has been revised in the lower thermosphere and extended into the mesosphere, stratosphere and lower atmosphere to provide a single analytic model for calculating zonal and meridional wind profiles representative of the climatological average for various geophysical conditions.

Gravity wave activity in the lower atmosphere: Seasonal and latitudinal variations
Simon J. Allen,Robert A. Vincent +1 more
TL;DR: A climatology of gravity wave activity in the lower atmosphere based on high-resolution radiosonde measurements provided by the Australian Bureau of Meteorology is presented in this article, where the vertical wavenumber power spectra of normalized temperature fluctuations are calculated within both the troposphere and the lower stratosphere and compared with the predictions of current gravity wave saturation theories.

Interpretations of observed climatological patterns in stratospheric gravity wave variance
TL;DR: In this paper, a linear model of gravity wave propagation is applied to investigate the underlying causes of some of the observed patterns, and the model shows that this coupling can give rise to geographical, seasonal, and vertical variations in gravity wave observations without any variations in the spectrum or amplitude of the sources in the troposphere.

A Climatology of Gravity Wave Motions in the Mesopause Region at Adelaide, Australia
TL;DR: In this paper, a statistical study of gravity wave motions in the mesosphere and lower thermosphere measured with a MF partial reflection radar located at Buckland Park new Adelaide (35°S, 138°E) in the period November 1933 to December 1984 is presented.
