Talk: Ashot Chilingarian: Ship 1: "ON THE INITIATION OF LIGHTNING IN THUNDERCLOUDS", Ship 2: "ENHANCED PARTICLE FLUXES DURING THE DECAY STAGE OF ARAGATS THUNDERSTORMS", Ship 3: "THE RUNAWAY BREAKDOWN PARTICLES SPECTRA OBTAINED JUST BEFORE THE LIGHTNING STROKE"

Abstracts: "ON THE INITIATION OF LIGHTNING IN THUNDERCLOUDSAbstract. The newly emerging field of high- energy physics in the atmosphere involves measuring as many parameters as possible, such as particle fluxes, electric-field disturbances, radio emissions from the thunderclouds, and meteorological environments. The intensity of the Thunderstorm Ground Enhancement (TGE, [1]) analyzed in the present study was observed by 3 cm thick scintillators with a sensitive area of 1 m. sq. operated in the particle counter mode. The energy release spectra of gamma ray and electron content of avalanches unleashed in the cloud were measured by the 60 cm thick plastic scintillator equipped with veto system for charged particles. We estimate the height of cloud and compare the estimated maximal energy of electrons and gamma rays with simulated ones [2]. It is the first report on Runaway Breakdown (RB) electrons spectrum measured just before the lightning stroke.

 

"ENHANCED PARTICLE FLUXES DURING THE DECAY STAGE OF ARAGATS THUNDERSTORMS" Abstract. The bulk information on particle fluxes correlated with thunderstorm can be used to better understand the electrical structure of thunderclouds. The only very specific electric configuration of the lower part of the cloud can support the sustainable acceleration of the electrons. Our analysis is based on the thunderstorm data from the Aragats Mountain in Armenia, 3200 m above sea level Varieties of particle detectors located at Aragats Space Environmental Center are registering neutral and charged particle fluxes correlated with thunderstorms, so-called Thunderstorm Ground Enhancements (TGEs, [1]). In the present paper, we relate particle fluxes to the electrical structure of thunderclouds, namely, to an end-of- storm oscillation (EOSO) during the storm’s decay phase.

United Nations/United States of America Workshop on the International Space Weather Initiative: The Decade after the International Heliophysical Year 2007

Dates: 31 July - 4 August, 2017

Location: Boston Collage, Massachusettes, USA

Talk: A. Chilingarian, V. Babayan, T. Karapetyan, B. Mailyan, M. Zazyan: Worldwide Network of Particle Detectors SEVAN: 10 Years of Operation

Abstract: In 1957, in a display of unprecedented international cooperation, more than 66.000 scientists and engineers from 67 nations participated in the International Geophysical Year (IGY1957). Fifty years on, the International Heliophysical Year (IHY 2007) again drew scientists and engineers from around the globe in a coordinated; more...IHY-10.pdf
