Response of outer ionosphere electron temperature and density to changes in solar activity.
Manifestation of solar activity variation in the electron temperature (Te) and electron density (Ne) during the solar maxima is studied. Solar activity changes are characterized by the F10.7 index...

Variations of daytime and nighttime electron temperature and heat flux in the upper ionosphere, topside ionosphere and lower plasmasphere for low and high solar activity
LEO satellite easurements is used for studying the solar activity variations of Te. The Te data are grouped for two levels of solar activity, five altitude ranges for. We have found that Te increases with...

Effects of Solar Active Regions on Meridional Flows
The aim of this work is to study the solar-cycle variations of meridional flows and to investigate their variations in magnetic regions. Helioseismology observations indicate that mass flows around active regions a...
