Climatology of short-period mesospheric gravity waves over Halley, Antarctica (76°S, 27°W)
TL;DR: The wave headings exhibited unusually strong anisotropy with a dominant preference for motion towards the Antarctic continent and a rotation from westward during fall, to poleward in mid-winter, to eastward in spring.

Quantifying gravity wave momentum fluxes with Mesosphere Temperature Mappers and correlative instrumentation
David C. Fritts,P.-Dominique Pautet,Katrina Bossert,Michael J. Taylor,Bifford P. Williams,H. Iimura,Tao Yuan,Nicholas J. Mitchell,Gunter Stober +8 more
TL;DR: In this article, a method for quantifying gravity wave (GW) pseudo-momentum fluxes accompanying spatially and temporally localized GW packets is presented. But the method is limited to two events, each of which involves superpositions of GWs having various scales and character, and each case was found to achieve transient, but very large, momentum fluxes with magnitudes varying from ~60 to 940 m2 s−2.

Analysis and Modeling of Ducted and Evanescent Gravity Waves Observed in the Hawaiian Airglow
TL;DR: In this article, the authors report specific cases where wave structure is significantly determined by the local wind struc- ture, and where wave characteristics are consistent with ducted or evanescent waves throughout the mesopause re-gion.

TL;DR: An all-sky CCD imager for the OH, O 2 and OI (557.7 nm ) airglow emissions was operated at Cachoeira Paulista (CP), Brazil (23°S,45°W), in collaboration with Utah State University, USA, during the period of 1998-2000 as mentioned in this paper.

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.
