“…The results of the analysis of these effects at middle and high latitudes are given in many studies and are consistently reflected in the surveys (Roble, 1985;Rycroft et al, 2012) (including the solar event in August, 1972). Similar solar events occurred in October 2003 andNovember 2004. A detailed analysis of temporal varia tions in the electric field strength and electric conduc tivity of air in the near Earth atmosphere of Kam chatka during these events was conducted by us earlier (Smirnov et al, , 2014.…”

“…Similar solar events occurred in October 2003 andNovember 2004. A detailed analysis of temporal varia tions in the electric field strength and electric conduc tivity of air in the near Earth atmosphere of Kam chatka during these events was conducted by us earlier (Smirnov et al, , 2014. In these works, we have considered simultaneously observed variations in the local meteorological parameters (temperature, pres sure, humidity, and wind speed), as well as solar and geomagnetic parameters (fluxes of X ray radiation as an indicator of the level of solar activity, the fluxes of solar and galactic cosmic rays, Dst variations, Kp indices, and the horizontal component of the geo magnetic field).…”

We perform spectral analysis of records of meteorological (temperature, humidity, pressure of the atmosphere) and electrical (strength of quasi static electric field and electric conductivity of air) parameters observed simultaneously at the Paratunka observatory during the solar events of October 21-31, 2003. Also, we use simultaneous records of X ray fluxes of solar radiation, galactic cosmic rays, and the horizontal com ponent of the geomagnetic field. We show that the power spectra of the meteorological parameters under fine weather conditions involve oscillations with a period of thermal tidal waves (T ~ 12 and 24 h) caused by the influx of thermal radiation of the Sun. During strong solar flares and geomagnetic storm of October 29-31 with a prevailing component of T ~ 24 h, their spectra involve an additional component of T ~ 48 h (the period of planetary scale waves). With the development of solar and geomagnetic activities, the power spectra of atmospheric electric conductivity and electric field stress involve components of both thermal tidal and plan etary scale waves, which vary highly by intensity. In the power spectra of galactic cosmic rays accompanying the strong solar flares, components with T ~ 48 h were dominant with the appearance of additional (weaker by intensity) components with T ~ 24 h. The simultaneous amplification of components with T ~ 48 h in the power spectra of electric conductivity and electric field strength provides evidence of the fact that the lower troposphere is mainly ionized by galactic cosmic rays during strong solar flares and geomagnetic storms. The specified oscillation period with T ~ 48 h in their spectra, as well as in the spectra of X ray radiation of the sun, is apparently caused by the dynamics of solar and geomagnetic activities with this time scale.

“…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 ., ; Nikiforova et al ., ; Kleimenova et al ., ; Smirnov et al ., ]. 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.

“…Consequently, besides cyclones, impact of other sources of additional thermal energy, penetrating into the near-ground atmosphere to form thunderstorm clouds, is also possible. Indeed, in the papers [1,2] it was discovered that thunderstorm processes appeared after powerful solar flares accompanied by solar radiation increase in spectrum visible and infrared ranges. Moreover, the authors [3] also found thunderstorm phenomena 6-7 days before strong earthquakes with magnitude M > 8.…”

Winter thunderstorms in Kamchatka

Winter thunderstorms in Kamchatka are rare meteorological phenomena. To investigate the nature of this phenomenon, time variations of quasistatic electric field and meteorological quantities at «Paratunka» observatory, IKIR FEB RAS (φ = 52:97° N; λ = 158:25° E), and the data on solar, seismic and cyclonic activities available in INTERNET were used as a thunderstorm activity indicator. It was shown that powerful solar flares accompanied by radiation increases in visible and infra-red spectra as well as the Earth infra-red radiation entering the atmosphere before powerful earthquakes with magnitude M > 8 may be additional sources of heat in the near-ground atmosphere of Kamchatka. The impact of tropical cyclones on the processes of thunderstorm activity formation in Kamchatka during weak seismic activity has been determined insufficiently and requires further detailed investigation.
