The quasi-two-day oscillation of wind velocities in the lower thermosphere

Using numerical modeling for the principal seasons of the year, the structure of the natural oscillation of the atmosphere having a period of 51 hr and a zonal number, s, of 3 is determined. The computational results are compared with experimental data describing the quasi-two-day oscillation of wind velocities in the lower thermosphere. The effect of Hall conductivity and zonal wind on Rossby waves, in particular, the quasi-two-day oscillation, is discussed theoretically. Data in the literature on the quasi-two-day oscillation are synthesized, and new experimental data are presented.
