This is a general review of the existing climatological models of ionospheric
radio scintillation for high and equatorial latitudes. Trans-ionospheric
communication of radio waves from transmitter to user is affected by the
ionosphere which is highly variable and dynamic in both time and space.
Scintillation is the term given to irregular amplitude and phase fluctuations of
the received signals and related to the electron density irregularities in the
ionosphere. Key sources of ionospheric irregularities are plasma instabilities;
every irregularities model is based on the theory of radio wave propagation in
random media. It is important to understand scintillation phenomena and the
approach of different theories. Therefore, we have briefly discussed the theories
that are used to interpret ionospheric scintillation data. The global morphology
of ionospheric scintillation is also discussed briefly. The most important (in
our opinion) analytical and physical models of scintillation are reviewed here.
