TL;DR: In this article, the authors study the momentum deposition in the thermosphere from the dissipation of small amplitude gravity waves (GWs) within a wave packet using a fully nonlinear two-dimensional compressible numerical model.

TL;DR: In this article, the average, background, horizontal neutral winds at z ∼ 160-240 km were calculated for a GW on December 13, 2006 using Advanced Modular Incoherent Scatter Radar (AMISR) data.

TL;DR: In this article, an instrumented sounding rocket launched from Wallops Island Virginia has flown through a midlatitude spread F (MSF) event in conjunction with simultaneous ionosonde, HF radar, and 244 MHz scintillation observations from the ground.

TL;DR: Vadas et al. as mentioned in this paper showed that the vertical wavelength λz of the surviving GWs increases approximately exponentially with altitude up to z ∼ 220 km, where the mean free path becomes a substantial fraction of the density scale height.

TL;DR: In this paper, a satellite analysis of gravity wave propagation generated by hurricane event from the troposphere through the stratosphere and mesosphere into the ionosphere is presented. And the authors also briefly discuss the vertical and horizontal propagation of the Hurricane Matthew induced GWs and TIDs.
