“…The nighttime temperature increase on 2 April may be explained by bad weather conditions, but on the following days up to 7 April, this increase was possibly associated with solar flare effects. A similar effect was observed during magnetic storms on November 2004 (Smirnov et al 2013). In light (Danilov and Lastovika 2001) of the possible mechanisms for geomagnetic storm effects on the troposphere, it is a dynamic mechanism associated with the increase of acoustic-gravitation atmospheric waves at the planetary scale; it is an electric mechanism associated with the global electric circuit and cosmic ray penetration into the atmosphere; it is an optical mechanism associated with atmosphere transparency changes and chemical contents in the stratosphere under the influence of short-wave radiation of the Sun and GCRs.…”

“…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

“…This is, for example, the study of processes in the magnetosphere and the ionosphere, including the processes with regional scales or related to Space Weather [18], [19], the study of the Earth's interior [20], the correlation of geophysical processes in the near-Earth atmosphere [21] and many others. An important applied aspect of magnetic measurements is the possible connection between variations of geophysical fields, for example, between magnetic field and seismicity of Kamchatka [22], [23].…”

Abstract. Continuous magnetic measurements at Geophysical Observatory "Paratunka" (PET) of IKIR FEB RAS are performed since 1967. In the new millennium analogue magnetometers were modernized to digital, the technologies of absolute observations were changed, the data processing was completely transferred to computers, and the status of INTERMAGNET observatory was obtained. Currently, the observatory uses the following magnetometers: (a) for absolute observations -DIflux LEMI-203 (theodolite 3T2KP) and Mag-01 (theodolite Wild-T1), Overhauser magnetometers POS-1 and GSM-19W; (b) for variation measurements -fluxgate magnetometers FGE-DTU, FRG-601 and MAGDAS (installed under international agreements of IKIR), vector magnetometers dIdD GSM-19FD and POS-4 with Overhauser sensors and coil systems, scalar magnetometer GSM-90 and induction magnetometer STELAB. During Spring-Autumn season dIdD also is installed at remote station "Karymshina" at distance of 15 km from Observatory. There is monitoring system for monitoring of conditions in which magnetic observations are performed, including the semi-professional weather stations Davis Vantage Pro2 and WS2000 and a network of digital temperature sensors DS19B20 located at various points in magnetic pavilions and outdoor. All measurements are synchronized with the UTC. The results of observations are collected by the IKIR data server from the recorders and loggers, including in real-time. Specialized software was developed (based on MATLAB and Octave packages), which allows automatic and semi-automatic processing of data, the comparison of the results from different magnetometers and presenting final data in formats, defined by international standards, including INTERMAG-NET. Significant efforts of observatory staff are direct to archive (raw) magnetic data, a significant part of which has not been entirely processed, is not presented in international data centers and is still not available to the scientific community. Digital images of analog magnetograms have been obtained, the digitization of which allowed to fill the gaps in the hourly data available in the WDC for 1991, 1996-1997. The state of the set of the instruments and databases shows that the observatory "Paratunka" can solve most of the problems that arise in the geomagnetic field researches, including the provision of data for the development of regional and global field models, ground support of magnetometers located on satellites, support of the surface (sea) and aeromagnetic surveys and Solar-Terrestrial Relations and Physics of Earthquake Precursorsdrilling, providing the data for researches of processes in the lithosphere, magnetosphere and ionosphere over a wide frequency range, and also for a number of applied problems.

“…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

et al. 2019

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.
