“…Thus, runaway breakdown is much more probable than the conventional breakdown in creating lightning discharges in a thunderstorm. GCRs with energies *10 14 -10 16 eV could initiate extensive air showers (EASs) and produce energetic secondary electrons and initiate lightning discharges (Gurevich et al 2009a, b;Chubenko et al 2009;Chilingarian et al 2009). However, it is not yet possible to identify the percentage of lightning discharges triggered by GCRs.…”

“…One event was recorded during the initial phase of a thunderstorm and three during the main phase. Chubenko et al (2009) measured the energy spectrum of gamma radiation during the stepped leader of lightning and the total energy is estimated as *10 -3 to 10 -2 J. The measurements were carried out at the Tien-Shan mountain cosmic ray observatory situated at the height of 3.34 km above sea level, which is an average height of thunderclouds at Tien-Shan.…”

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.

“…The flashes are usually widespread sometimes correlated with EAS [2]; b) short gamma-flashes lasting 600-800 µs [3]; c) long-lasting gamma ray bursts 100-600 ms. The burst consists of multiple random flashes and it is directly connected with atmospheric discharge.…”

The bursts of high energy events observed by the telescope array surface detector R.U. Abstract. Experimental work of the past few years has shown that runaway breakdown determines the maximum electric field strength in thunderclouds and is behind a variety of phenomena newly observed in thunderstorm atmosphere, such as TGFs, TLEs, etc. The necessary condition for the occurrence of runaway avalanche is the existence of high-energy electrons. In the atmosphere, these are the cosmic ray secondary electrons. Therefore the observed effects reflect close relationship between cosmic rays and electrodynamic processes in a thunderstorm atmosphere. The Tien-Shan high-altitude cosmic ray station is a unique site for investigations effects of cosmic rays and thunderstorm discharge. "Thunderstorm" detector complex is designed especially for a systematical study of atmospheric discharges by the means of simultaneous recording of the different kinds of radiation. The presence of a widespread extensive air shower trigger set-up at the Tien-Shan station permits to study the role of energetic cosmic ray particles in lightning development. Overview of main results, obtain during last several years at the Tien-Shan are presented. A phenomenological description and theoretical vision of the cosmic rays role in atmosphere processes during thunderstorm are discussed.

“…Dark lightning may be viewed as an ionizing radiation scattering explosion in clouds preceding the observation of natural lightning. Gamma rays cause dark lightning to emit X-rays which may be used to investigate lightning processes [10]. Joseph Dwyer (FIT) explains dark lightning as rapid electrons and positrons avalanche breakdown discharge within clouds causing x-rays emission before conventional white lightning.…”

Lightning is one of the fascinating phenomena exhibiting tremendous natural power. It is source of awe, curiosity, enticement, inspiration as well as fear. On average, 50 lightning strikes occur on earth in one second. Fortunately not all of them kill people, albeit 10% people fall prey to lightning annually, out of which hardly 20 to 25% die. Lightning injures victims by heat, shockwave, intense brightness, radio waves, and secondary slip or fall mechanisms. Lightning injury is different from the normal electric shock as it involves transient flashover unlike the electrical contact freeze, wherein alternating (AC) and direct currents (DC) pass through the conductive interior body. Vacuity in knowledge is the driving force behind discoveries and inventions. Lightning experts had hardly developed any concurrence on lightning physics, and the observation of dark lightning complicated the Gordian knot. Lightning preventive, alerting and control devices help reduce fatality rates by the bolts out of blue skies. Lightning was considered to be the second cause of death making natural disasters after flashfloods but preventive measures have slithered it down to the third place in developed countries. Lightning prevention rule recommends 'when the thunder roars, go indoors'. This work describes lightning characteristics, damage thresholds to humans, machines, energy infrastructures, airplanes, wind turbines, light railway tractions, underground cables and pipelines. Power and energy lifelines such as transmission lines, oil tankers and gas or petroleum pipelines are susceptible to lightning strikes. Artificial rocket and laser triggered lightning protection and control techniques help to divert the lightning attacks. Interaction of lightning with power and energy infrastructures disrupts these lifelines. However, lightning itself is viewed as an extraterrestrial energy source. Lightning energy harvesting is an interesting application which has been investigated quantitatively.
