“…However, the scope of information from the atmospheric electric field and current measurements on these effects remains limited and analysis of results obtained has not revealed any consistent features. This inconsistency may be due to the complexities of physical processes involved in the near-surface atmosphere for separate geo-effective storms and the selection of the measurement site [Mikhailova et al, 2009;Smirnov et al, 2013]. Observing the consequences of geomagnetic substorms on the atmospheric electric field or current from the network of stations (latitudinal/longitudinal) is still a difficult task, since the electrical variations are mostly controlled by the local weather conditions.…”

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.

“…The latter fact may be associated not only with the peculiarities of physical processes in the near-ground atmosphere for separate geomagnetic storms but also with the choice of registration location, for example, as well as the atmospheric state before and during a storm and so on. Earlier, the author of the paper investigated the effects of weak (Mikhailova et al 2009) and extreme (Smirnov et al 2013) geomagnetic storms on electric field intensity variations and meteorological value variations during an extreme storm in November 2004.…”

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
