| Zusammenfassung |
Collisional Rayleigh-Taylor
(RT) instability is considered in the bottom side of the equatorial F-region.
By a novel nonmodal calculation it is shown that for an applied shear flow in
equilibrium, the growth of the instability is considerably reduced. Finite but
small amounts of diffusion enhances the stabilization process. The results may
be relevant to the observations of long-lived irregularities at the bottom-side
of the F-layer.
Key words. Ionosphere (ionospheric
irregularities, equatorial ionosphere, plasma waves and instabilities) |
