THUNDERCLOUDS", Ship 2: "ENHANCED PARTICLE FLUXES DURING THE DECAY

Abstracts: "ON THE INITIATION OF LIGHTNING IN THUNDERCLOUDS" Abstract. 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
