“…Many researchers have investigated the impact of solar wind-induced geomagnetic storms on the atmospheric electrical parameters at middle and high latitudes [Apsen et al, 1988;Nikiforova et al, 2005;Kleimenova et al, 2008;Smirnov et al, 2014]. However, there are limited observations on simultaneous measurements of atmospheric electric field, geomagnetic fields, and other geophysical parameters by a network of polar stations over the Arctic regions and USSR.…”

The effects of a geomagnetic storm on the variation of the atmospheric electric field over Maitri (70°45′S, 11°44′E), Dome C (75°06′S, 123°20′E), and Vostok (78°27′S, 106°52′E) Antarctic research stations are presented in this paper. For the first time, the paper reports the simultaneous observations of the atmospheric electric field/potential gradient (PG) over the three high‐latitude stations at the Southern Hemisphere, and its associated changes due to a substorm phenomenon. PG data obtained from these three stations under fair‐weather conditions on 5 April 2010 are analyzed. The duration of geomagnetic disturbance is classified into three intervals, which contains three consecutive substorms based on the magnetic records of the Maitri station. The substorm is directly related to an enhancement of the magnetospheric convective electric field at high latitude, generally controlled by the solar wind parameters. It is found that the variation in the amplitude of PG depends on the magnetic latitude during substorm onset. During the substorm expansion phase, when the convection cell is at overhead, PG is significantly enhanced due to the downward mapping of the ionospheric horizontal electric field. The present observation demonstrated the changes on PG due to the spatial extension of the convection cell from high latitudes up to middle latitudes.

“…It is well know that the largest magnetospheric disturbances are happened in the main phase of magnetic storms and represented strong magnetic substorms at night side of the Earth. We found (Kleimenova et al 2008(Kleimenova et al , 2013 that the strongest effects of magnetic storm in mid-latitude Ez variations were observed not during the night but in the daytime.…”

“…The aim of this paper is to pay attention on some potential influence of the main factor of cosmic weather, such as geomagnetic storms and substorms, on variations of the atmospheric electric field Ez, and overview our most important results obtained during the last 15 years in the Ez investigations at high and low latitudes (Nikiforova et al, 2003(Nikiforova et al, , 2005Kleimenova. et al, 2008Kleimenova.…”

The atmospheric electric field (Ez) exists in the Earth's atmosphere at any location on the globe due the phenomenon called the global atmospheric electric circuit. This global circuit is controlled mainly by the world thunderstorm and shower clouds activity which act as generators, and the cosmic rays as well solar electromagnetic radiation, which modify its load. Moreover, the Earth's magnetosphere-ionosphere disturbances, caused by interaction with solar wind, could influence this state as well. Here we present an overview of our main results of the study of the potential effects in Ez caused by geomagnetic storms and substorms as an important factor of the space weather. Our results are based of the Ez observations at the mid-latitude Polish station Swider (near Warsaw) and high-latitude Polish station Horsund (Spitsbergen archipelago). The effect of magnetic storms, associated with a coronal mass ejection from the Sun, was detected in the mid-latitude atmospheric electricity as strong daytime Ez negative anomalies in relation with simultaneous occurrence of night-side magnetospheric substorms. However, at high-latitudes, the auroral-latitude magnetic substorm lead to the simultaneous polar-latitude Ez deviations, positive in the local morning and negative in the evening, corresponding to the station's location relative to the "positive" or "negative" center of the polar ionosphere convection vortex. Thus, ground-based Ez recordings could be one of the very sensible tools to study solar windmagnetosphere-ionosphere-atmosphere interactions.

“…Then, a long negative phase began with a gradual recovery of the electric field during the following 10 days. During strong geomagnetic storms, including the storm on 30 October 2003 (Nikiforova et al 2005;Kleimenova et al 2008) at the 'Svider' station, decreases of the potential gradient were registered. Co-occurrences in the time of their duration with the duration of splashes of riometric absorption in the subauroral zone allowed the authors to suggest that 'the reason for the appearance of negative values of potential gradient may be the increase of upper atmosphere conductivity caused by precipitation of energetic electrons into subauroral latitudes' (Nikiforova et al 2005).…”

The effects of a geomagnetic storm on 5 April 2010 on electric parameters of the atmospheric near-ground layer in Kamchatka have been investigated. Three processes over the course of the storm were identified. Air electroconductivity began to decrease 4 h before the storm, and this lasted for 20 h. The storm's sudden commencement caused potential gradient oscillations with amplitudes up to 300 V/m. During the stages of the storm, a significant increase in the atmosphere ion content unipolarity coefficient occurred. Findings
