Ionospheric scintillation
TLDR
In this article, available observations of ionospheric scintillation are analyzed to evaluate the adequacy of existing models used for the interpretation of scintillant data. And the authors used the models were used to construct Scintillation occurrence distribution functions.Abstract:
Available observations of ionospheric scintillation are analyzed to evaluate the adequacy of existing models used for the interpretation of scintillation data. The theoretical models are reviewed and the frequency and propagation geometry dependences predicted by the models are compared with the observations. The models were used to construct scintillation occurrence distribution functions which show that scintillation phenomena significantly affect the design of transionospheric radar or communication systems operating at frequencies below 1 GHz. Diversity schemes useful for mitigation of scintillation effects are considered. Mention is made of the geophysical processes thought to be responsible for scintillation.read more

Polarization fields produced by winds in the equatorial F-region
TL;DR: In this article, the E-layer conductivity may be too small to close this circuit, so that polarization fields build up in the F-layer, causing the plasma to drift with the wind.
