Research in Gravity Waves and Airglow Phenomena.
Abstract
The research in this final report may be divided into three parts. The first part deals with the behavior of airglow (mid-latitude) under the influence of atmospheric gravity wave model is assumed. Our principal objective here is to examine its effect on the ionosphere and the 6300 A OI 5200 A NI emission lines. The second part deals with a new approach for treating gravity waves. The gravity wave problem can be reduced into a multi-channel scattering problem with effective potentials for each channel. The potentials for the gravity channel corresponding to different exospheric temperatures were obtained from the 1972 Cospar models. The third part is an investigation of the non-linear effects of gravity wave on natural oscillations. Airglow (mostly 5577 A OI) oscillations often show a small period (8-14 min.) oscillation superimposed on a long period (approx. hour) oscillation. The short period oscillation is sometimes excited by the long period oscillation as the latter increases in amplitude.
