The Proceedings of International Symposium Thunderstorms and Elementary Particle Acceleration (TEPA 2015) are Published
The
problem of how lightning is initiated inside thunderclouds is probably one of
the biggest mysteries in the atmospheric sciences. Recently established high
energy processes in the atmosphere, i.e. Terrestrial Gamma Flashes (TGF) –
brief bursts of gamma rays observed by orbiting gamma ray observatories and
Thunderstorm Ground Enhancements (TGEs) – sizable long-lasting fluxes of
electrons, gamma rays and neutrons detected on Earth’s surface are correlated
with thunderstorms. However, the relationship among thundercloud
electrification, lightning activity, and wideband radio emission and enhanced
particle fluxes have not been yet unambiguously established. One of the most
intriguing opportunities opened by the observation of the high-energy processes
in the atmosphere is their relation to lightning initiation and propagation.
With the objective to discuss these high-energy phenomena, the 5th annual conference
on Thunderstorms and Elementary Particle Acceleration (TEPA) was held at the
Nor Amberd International Conference Center of the Yerevan Physics Institute
(YerPhI) in Armenia. The Cosmic Ray Division of the YerPhI and Skobeltsyn
Institute of Nuclear Physics of Moscow State University organized the workshop;
YerPhI and the Armenian State Committee of Science sponsored it. Thirty
scientists and students from the United States, Japan, France, Germany, Israel,
Russia, and Armenia attended.
Presentations focused on observations and models
of high-energy emissions in thunderclouds; on the termination of particle
fluxes by lightning; multivariate observations of thunderstorms from the
Earth’s surface and from space; radio emissions produced by atmospheric discharges
and particle fluxes; the influence of the Extensive Air Showers (EASes) on
lightning initiation and others.
In March, 2016 the Proceedings of symposium has
been printed by the TIGRAN METS printing house. The online version of the
manual can be found at http://www.yerphi.am/images/tepa-2015-21march-low.pdf

The next TEPA-2016 symposium is scheduled on October
3-7 in Nor Amberd international conference center.
