Equatorial electron densities—seasonal and solar cycle changes

  title={Equatorial electron densities—seasonal and solar cycle changes},
  author={Girija Rajaram and Reena Gogia Rastogi},
The effect of Season and Solar cycle on equatorial electron density distributions is examined in terms of the presently-understood dynamics of the ionosphere. While many of the features fit in well with the dynamics, the role of neutral winds seems to merit more importance than it has been given so far. The absence of a clear ‘noon-time bite-out’ in total electron content in the bottomside is rather puzzling in view of the fact that the E × B upward drift of ionization commences from altitudes… CONTINUE READING
