The Northward IMF Magnetosphere
The manner in which the Earth s magnetosphere responds to the solar wind is highly dependent upon the orientation of the interplanetary magnetic field (IMF), particularly the north–south (B Z ) component. As most auroral and geomagnetic activity occurs when the IMF is southward (or weakly northward, but dominated by the dawn–dusk [B Y ] component), it is perhaps unsurprising that these conditions have received the most attention. However, when the IMF is more strongly northward (B Z \textgreater 0 and B Z \textgreater \t ...

Influence of interplanetary solar wind sector polarity on the ionosphere
Knowledge of solar sector polarity effects on the ionosphere may provide some clues in understanding of the ionospheric day-to-day variability and \textquotedbllefthysteresis\textquotedblright effect on foF2. Ionospheric response to changes in solar sector polarity has not been fully documented previously, partly due to the limitation of observations. In this study, a solar-terrestrial connection ranging from solar sector boundary (SB) crossings, geomagnetic disturbances and ionospheric perturbations has been demonstrated ...

Importance of capturing heliospheric variability for studies of thermospheric vertical winds
Using the Global Ionosphere Thermosphere Model with observed real-time heliospheric input data, the magnitude and variability of thermospheric neutral vertical winds are investigated. In order to determine the role of variability in the Interplanetary Magnetic Field (IMF) and solar wind density on the neutral wind variability, the heliospheric input data are smoothed. The effects of smoothing the IMF and solar wind and density on the vertical winds are simulated for the cases of no smoothing, 5-minute, and 12-minute smoot ...

Spatial and temporal ion drift variability in the high -latitude F region during southward IMF
The purpose of the following research is to investigate the role and contribution of variability or structure in the ion drift to the overall Joule heating rate during times of southward interplanetary magnetic field (IMF). This investigation is limited to southward IMF because the convection patterns are generally more stable and reproducible than those seen for a northward IMF. This allows us to organize the data according to features of the convection pattern and thus produce results that can be used in model simulations ...
