“…Fair-weather E z and J z variations at high latitudes observed during solar wind induced M-I events are usually showing signatures of remarkable variety of shapes and magnitudes. Early polar atmospheric electric field recordings (Israël 1973;Lobodin and Paramonov 1972) made in fair-weather conditions during aurora and high magnetic activity had been bringing disparate and not consistent and repeating results. After year-long recordings in Alaska, Shaw and Hunsucker (1977) concluded that under similar circumstances there had been no response in E z at all.…”

This paper reviews individual cases of the relationships between variations of solar wind parameters and variations of the DC vertical atmospheric electric field, $$E_z$$ E z , and current density, $$J_z$$ J z , measured at ground level in the Arctic, at the S. Siedlecki Polish Polar Station Hornsund, Spitsbergen (Svalbard, Norway), and at the mid-latitude S. Kalinowski Geophysical Observatory in Swider (Poland). A considerable number of events from Hornsund confirmed previous observations of regularity of effects related to the station’s position against the location of the potential bays of ionospheric convection and polar electrojets, observed in other polar locations, as well as effects of other polar cap current systems. This allowed us to conclude that the physical dependence of ground-level $$E_z$$ E z and $$J_z$$ J z on solar wind changes produce measurable effects which do not require statistical analysis to be observed. We can also expect that the dependence does exist, especially in strongly disturbed circumstances, e.g., following solar flares and Earth-directed coronal mass ejections, at middle latitudes. However, further investigations of these physical relationships by this approach are practically almost impossible since a very large number of variable parameters simultaneously affect the recorded lower atmospheric variables. In addition, results of quantitative analysis of predicted and observed effects are not satisfactory. Future research studies require more efficient ways of investigation by theoretical treatment and modelling work using existing and novel observational data besides taking advantage of scientific progress in magnetospheric physics.

“…The change of ΔPG may also possible by the energetic particle (electron and proton > 10 MeV) precipitation over high-latitude ionosphere that alters the conductivity of upper atmosphere. This change in ionospheric conductivity substantially decreases/increases the vertical ionospheric potential (PG) [Lobodin and Paramonov, 1972;Yeoman et al, 2000;Nikiforova et al, 2005;Kleimenova et al, 2008].…”

Variation of atmospheric electric field measured at Vostok, Antarctica, during St. Patrick's Day storms on 24th solar cycle

The influence of solar wind‐magnetosphere interaction on the atmospheric electric field is investigated in connection with the two severe geomagnetic storms during 24th solar cycle. The observation was carried out at Vostok (78°27′S, 106°52′E), Antarctica, during 17–18 March 2013 and 17–18 March 2015. Two consecutive substorms were observed at Vostok during the main phase of geomagnetic storms, where the disturbed ionospheric current is antisunward in the morning sector (~04:00–10:00 UT) and sunward in the noon‐afternoon sector (~11:00–16:00 UT). Interplanetary magnetic field (IMF) and solar wind interaction enhance the ionospheric potential, which in turn couple with Potential Gradient (PG) measured at ground level. Eventually, for the first time, the slope of ~1.0 Vm−1 per kV has been demonstrated between Vostok PG and overhead ionospheric potential (Weimer_05) during intense (Kp = 8) geomagnetic perturbation. The linear relation between PG and overhead potential is highly significant on positive coupling, i.e., positive ΔPG changes, whereas the offset of ~25 V/m has been estimated with negative coupling. Ionospheric convection map from Super Dual Auroral Radar Network is more compatible with PG on positive coupling, and for negative changes of PG, radar observation is more consistent than the Weimer_05 model. Ionospheric electric potential from radar observation and empirical model is highly compromised when a polar cap is dominated by a single negative potential region associated with IMF By ≪ 0. It is inferred that superposed overhead ionospheric potential on Vostok PG is highly effective when IMF maintained a steady flow, whereas it is less significance for rapid changes of solar wind‐IMF parameters.

“…The energetic charged particles precipitating from the Earth's inner and outer magnetospheric radiation belts interacts with the middle atmosphere by increasing the ionization directly or via bremmstrahlung radiation, by altering its chemistry (Jackman et al 1995) or by affecting the nucleation by the electro freezing of droplets from clouds, thereby influencing the dynamics of storm and atmosphere (Tinsley and Heelis, 1993;Tinsley, 1996Tinsley, , 2000. Freier (1961) and Lobodin and Paramanov (1972) reported auroral effects on vertical electric field measured on the ground. In general, they reported a decrease in the electric field that later recovers to pre auroral condition.…”

The global component of fairweather electricity is subject to special attention to watch the solar-terrestrial effects and secular changes in climate. It is generally considered that the diurnal variation of atmospheric electricity parameters, if they are not following the Carnegie pattern, are not representative of the global thunderstorm activity. Some of the results obtained from Maitri (70°45'54"S, 11°44'03"), are discussed here in context with global thunderstorm activity and space weather influences. The diurnal pattern of the Potential Gradient and current density strongly deviate from the Carnegie curve. We have showed that this deviation is not due to the local electrical influence but due to the global thunderstorm activity. During fairweather condition the parameters are representing the global thunderstorm activity and to some extent they respond to the upper atmospheric electro dynamic phenomenon. The mean value of the potential gradient (77.7 V/m) and current density (2.13 pA/m 2 ) well below the expected global mean but close to the value reported from the same location and season in the past years. The mean conductivity, 3.34 x 10 -14 mhom -1 , is slightly at higher side and they exhibit a different diurnal trend comparing to the past measurements at this location.
