TL;DR: In this paper, the advective effects on cloud visibility and structure for a range of viewing angles and cloud layer widths have been investigated and the gravity wave breaking signature has been used to provide a plausible explanation of the observed structures and suggest that noctilucent cloud structures may be used to infer qualitative properties of gravity wave scales, energy and momentum transports, and turbulence scales near the summer mesopause.

TL;DR: In this article, the spectral linear solutions that arise in response to local 3D body forces and heatings in an idealized environment that turn on and off smoothly but not necessarily slowly over a finite interval in time were determined.

TL;DR: In this paper, the authors used the results of the SpreadFEx campaign to estimate gravity wave characteristics at the bottomside F layer, and to assess their possible con- tributions to optimal seeding conditions for equatorial spread F and plasma instability growth rates.

TL;DR: In this paper, the authors present results from the first fully three-dimensional direct numerical simulations of initially turbulent wakes with net momentum in unstratified and density stratified fluids.

TL;DR: In this paper, the authors used density measurements obtained during aerobraking (AB) on Mars Global Surveyor and Mars Odyssey to examine mean densities and the characteristics and variability of gravity waves (GWs) in the upper atmosphere of Mars.
