TL;DR: In this article, a mesospheric heating event was observed over Haleakala, Maui, on October 21, 1993 (day 294), during the ALOHA-93 Campaign, consisting of a persistent, narrow temperature-inversion layer about 3-4 km wide near 87 km altitude with a peak temperature rise approaching 40 k, lasting for about 3.5 hours.

TL;DR: In this paper, a wave structure with a sharp front covering significant parts of the sky was observed to move with a phase velocity of 76 m/s at a period of 4 to 5 min.

TL;DR: The nonisothermal Richardson number becomes negative as early as 0930 UT, indicating conditions conducive to the development of convective instability and turbulence as mentioned in this paper, and the possibility that turbulence could exist at times earlier than previously thought explains the large temperature increase observed before 1000 UT.

TL;DR: In this paper, a spectral full-wave model and a 2-dimensional (2-D) fully nonlinear chemistry model were used to investigate the latitudinal variations of the wave effects on the minor species in the mesosphere/lower thermosphere region.

TL;DR: In this article, a 2D, time-dependent, fully nonlinear OH chemistry-dynamics model was used to investigate the effects of gravity wave packet on the 8,3 airglow (8,3) band and the intensity-weighted temperature induced by a gravity wave at three latitudes in the northern hemisphere in the Mesosphere/Lower Thermosphere region.
