Dynamics of Atmospheric Gravity Wave Breaking in the Mesopause Region
… (MLT), and as a consequence of GW breaking, atmospheric turbulence plays an essential role in the mixing and transport of momentum, mass, and chemical materials in MLT. The main focus of this research for the fulfillment of the proposed Ph.D. dissertation is to improve the understanding of …

Fabry-Perot Observations of Midlatitude Neutral Winds and Atmospheric Gravity Wave Activity
… the upper atmosphere is modulated by a number of atmospheric waves propagating upward from various sources in the lower atmosphere. Among these are atmospheric gravity waves which have been recognized as a major source of momentum and energy in the mesosphere and lower thermosphere as well as a …

Observation and Interpretation of the Spectra of Atmospheric Gravity Wave Perturbations With Upward and Downward Phase Progressions
… 2$\pi$/(120 min) and 2$\pi$/(12 min) or vertical wave numbers between m = 2$\pi$/(10km) and 2$\pi$/(1km), approximately two-thirds of the density variance was associated with perturbations exhibiting downward phase progression (i.e., upwardly propagating waves). The nightly variances were highly …

Theoretical and Experimental Study of Gravity Waves in the Ionosphere Observed With Incoherent Scatter Radar
In the Worldwide Atmospheric Gravity Wave Study (WAGS) campaign, the source-response relationship between the auroral activities and the gravity waves observed in the ionosphere was studied. Ionospheric parameters observed with the incoherent scatter radars at Sondrestrom and Millstone Hill were …
