Stationary internal waves in the upper atmosphere with allowance for inhomogeneity, nonlinearity, and losses

Geomagnetism and Aeronomy. 2015. Vol. 55. No. 5. P. 658-662.

The possibility of the existence of a solitary internal gravity wave at heights of the Earth’s thermosphere is considered. Analytical results were obtained in local approximation with weak nonisothermality of the atmosphere. For internal gravity waves, the Korteweg–de Vries equation was derived and studied with allowance for inhomogeneity, nonlinearity, and dissipation. The theoretical results were used to interpret the main parameters of solitary intermittent ionospheric disturbances observed at heights of the F region of the ionosphere.
