“…Chilingarian et al [15] found a deficit of ~6.0% in the flux of muons with energies greater than 200 MeV during thunderstorms. Alexeenko et al [11] studied the effects of thunderstorms electric field on the soft and hard components of cosmic rays separately.…”

Monte Carlo simulations are performed to study the correlation between the ground cosmic ray intensity and near-earth thunderstorms electric field at YBJ (4300 m a.s.l., Tibet, China).The variations of the secondary cosmic ray intensity are found to be highly dependent on the strength and polarity of the electric field. In negative fields and in positive fields greater than 600 V/cm, the total number of ground comic ray positrons and electrons increases with increasing electric field strength. And these values increase more obviously when involving a shower with lower primary energy or a higher zenith angle. While in positive fields ranging from 0 to 600 V/cm, the total number of ground comic ray positrons and electrons declines and the amplitude is up to 3.1% for vertical showers. A decrease of intensity occurs in inclined showers within the range of 0−500 V/cm, which is accompanied by smaller amplitudes. In this paper, the intensity changes are discussed, especially concerning the decreases in positive electric fields. Our simulation results are in good agreement with ground-based experimental results obtained from ARGO-YBJ and the Carpet air shower array. These results could be helpful in understanding the acceleration mechanisms of secondary charged particles caused by an atmospheric electric field.

“…The intensity enhancements of ground cosmic rays have been detected by high altitude experiments, such as the Carpet air shower array [10,11], EAS-TOP [12], ASEC [13][14][15][16][17] and ASγ [18]. Their results indicated that the increases were associated with the electric field and the RREA process could be responsible for huge TGEs.…”

“…Simultaneous enhancements of γ ray and n fluxes during thunderstorm ground enhancements at ≈ 3200 m in Aragats Space Environmental Center (ASEC) are reported in [18]. Photonuclear reactions of the γ rays born in the RB (now referred to as relativistic runaway e avalanche, RREA) process with the air were considered as the main process responsible for the copious n production.…”

“…Photonuclear reactions of the γ rays born in the RB (now referred to as relativistic runaway e avalanche, RREA) process with the air were considered as the main process responsible for the copious n production. The authors of [18] consider also the mesoatom nuclei decay as a possible source of additional n observed by NM due to increase of µ-accelerated in the thunderclouds. A huge event observed at ASEC by several detectors supports the existence of long-lasting particle multiplication and acceleration mechanisms in the thunderstorm atmosphere [13].…”

for the JEM-EUSO CollaborationThe main scientific task of JEM-EUSO is to observe the ultra high energy cosmic rays by looking the atmosphere from space [1,2,3,4]. The detailed description of various sources of the background is important. On the other hand, the study of selected magnetospheric, ionospheric and atmospheric processes related to temporal and spatial variability of UV (ultraviolet) on the orbit where JEM-EUSO is supposed to be situated, could be a useful by-product of the main task of the project (e.g. review [5]). We attempt to summarize selected processes connected with atmospheric electricity and with energetic particles having links to the events as TLE (transient luminous event), TGF (terrestrial gamma-ray flash) and TGE (thunderstorm ground enhancement), recently observed on mountains too. Our groups (in CBK Warsaw, in IEP Košice) have a long track of experience with measurements of waves and particles for magnetospheric/ionospheric research as well as with physical analysis/interpretation of the data obtained. The JEM-EUSO, if the experiment is augmented by a very simple device that monitors energetic particles, and coordinated with other satellite measurements and with ground based observations, may be of relevance for some space weather studies related to the effects in the chain magnetosphere/ionosphere/atmosphere. This can contribute to better understanding of electromagnetic responses of lightning on the Earth and of selected processes at high altitudes in the atmosphere.

“…The first evidences of a surplus neutron radiation at thunderstorm time have been reported in [2]. In recent years, some papers discuss the possibility of neutron generation in connection with powerful lightning discharges on the basis of experimental observations made at the mountain heights at Tien Shan [3,4], Aragats [5,6], Tibet [7], so as at the sea level in MSU [8] and Yakutsk [9]. Up to date, the different physical mechanisms were being discussed for explanation of thunderstorm related neutron production, but the nature this phenomenon still remains unknown.…”

The new results concerning neutron emission detection from a laboratory high-voltage discharge in the air are presented. Data were obtained with a combination of plastic scintillation detectors and 3 He filled counters of thermal neutrons. Strong dependence of the hard x-ray and neutron radiation appearance on the field strength near electrodes, which is determined by their form, was found. We have revealed a more sophisticated temporal structure of the neutron bursts observed during of electric discharge. This may indicate different mechanisms for generating penetrating radiation at the time formation and development of the atmospheric discharge.
