“…It is already known that atmospheric electric field variations can produce increase in the cosmic ray flux (Chubenko et al, 2003;Dorman, 2004;Lidvansky and Khaerdinov, 2007). They may produce increases in the UP and LOW signals and some times, for strong variations, in the TELESCOPE signal too.…”

“…In a number of experiments, a burst of gamma radiation during thunderstorms has been observed (Eack et al 1996;Chubenko et al 2003;Howard et al 2008). Gurevich et al (2009b) reported 4 events of runaway breakdown while an EAS passes through a thunderstorm.…”

The physics of solar forcing of the climate and long term climate change is summarized, and the role of energetic charged particles (including cosmic rays) on cloud formation and their effect on climate is examined. It is considered that the cosmic raycloud cover hypothesis is not supported by presently available data and further investigations (during Forbush decreases and at other times) should be analyzed to further examine the hypothesis. Another player in climate is lightning through the production of NO x ; this greenhouse gas, water vapour in the troposphere (and stratosphere) and carbon dioxide influence the global temperature through different processes. The enhancement of aerosol concentrations and their distribution in the troposphere also affect the climate and may result in enhanced lightning activity. Finally, the roles of atmospheric conductivity on the electrical activity of thunderstorms and lightning discharges in relation to climate are discussed.

“…On the other hand, γ-ray flux enhancements of longer duration of order 100 s were reported in limited environments like high mountains [4,5,6,7,8,9,10,11,12,13] and sea level locations in the coastal area of the Japan Sea. They are also called Thunderstorm Ground Enhancements(TGE's) [13].…”

We observed three $\gamma$-ray bursts related to thunderclouds in winter using the prototype of anti-neutrino detector PANDA made of 360-kg plastic scintillator deployed at Ohi Power Station at the coastal area of the Japan Sea. The maximum rate of the events which deposited the energy higher than $3\,$MeV was $(5.5 \pm 0.1) \times 10^2 {\rm /s}$. Monte Carlo simulation showed that electrons with approximately monochromatic energy falling downwards from altitudes of order $100\,$m roughly produced the observed total energy spectra of the bursts. It is supposed that secondary cosmic-ray electrons, which act as seed, were accelerated in electric field of thunderclouds and multiplied by relativistic runaway electron avalanche. We actually found that the $\gamma$-rays of the bursts entered into the detector from the direction close to the zenith. The direction stayed constant during the burst within the detector resolution. In addition, taking advantage of the delayed coincidence detection of the detector, we found neutron events in one of the bursts at the maximum rate of $\sim 14\pm5\,{\rm /s}$.Comment: 16 pages, 7 figures; Accepted for publication in Physics Letters B; Figure 5 added, some minor changes in the tex
