Используя метод диагностики электрического состояния грозовой атмосферы по вариациям вторичных частиц космических лучей, регистрируемых установкой «Ковёр» БНО ИЯИ РАН, обнаружено явление взаимного влияния магнитосферной бури и грозовой активности. Установлено, что во время магнитосферных суббурь малой мощности, на предварительной стадии и в начале фазы развития, возможно проникновение магнитосферно — ионосферных возмущений на средние широты (∼40° с.ш.) над грозовыми очагами. Этот эффект проявляется в виде диффузного свечения типа «полярное сияние» яркостью ∼3 ·10-4 кд·м-² и локальных возмущений электрического поля с характерной разностью потенциалов в тропосфере ±100 МВ. Зарегистрировано локальное магнитное возмущение (∼1 нТл), соответствующее возникновению локального вертикального тока в атмосфере, максимум которого совпал с началом взрывной фазы зарождения суббури. Using the method of diagnosing the electrical state of a thunderstorm atmosphere by variations of the secondary particles of cosmic rays recorded by the Carpet air shower array of the Baksan Neutrino Observatory (North Caucasus), the phenomenon of the mutual influence of a magnetic storm and thunderstorm activity was discovered. It has been established that during magnetic substorms of low power, at the preliminary stage and at the beginning of the development phase, penetration of magnetospheric–ionospheric disturbances at mid latitudes (∼400 N) above lightning centers is possible. This effect manifests itself in the form of a diffuse glow of the aurora type with a brightness of ∼3 ·10-4 cd·m-² and local disturbances of the electric field with a characteristic potential difference in the troposphere of order of  ±100 MV. A local magnetic disturbance (∼ 1 nT) was recorded, corresponding to the appearance of a local vertical current in the atmosphere, whose maximum coincided with the beginning of the expansion phase of substorm nucleation.

The Telescope Array is the largest hybrid cosmic ray detector in the Northern hemisphere designed to measure primary particles in 4 PeV to 100 EeV range. The main TA detector consists of an air shower array of 507 plastic scintillation counters on a 1.2 km square grid and fluorescence detectors at three stations overlooking the sky above the air shower array. The experiment and its recent measurements - spectrum, composition, and anisotropy - is reviewed. Recently the construction of the TA Low energy Extension (TALE) detector, which consists of an additional fluorescence detector and an infill array, was finished. TALE lowers the energy threshold of TA down to 4 PeV. We are also constructing the TAx4 detector to increase statistics in particular at the highest energies. The current status and the future prospects of these new TAx4 experiments is reported.

A search has been made for very high energy photons from the direction of the Crab Pulsar using the Lodz extensive air shower array. This device is particularly suitable for such a study because it consists of a large muon detector which can be used to search for the characteristic muon poor showers.

A hybrid experiment has been started by the ASγ experiment at Yangbajing (4300m a.s.l.) in Tibet since May 2009, that consists of a high-energy air-shower-core array (YAC-I) and a high-density air-shower array (Tibet-III). In this paper, we report our results to check the hadronic interaction models SIBYLL2.3, SIBYLL2.1, EPOS-LHC and QGSJETII-04 in the multi-tens TeV energy region using YAC-I+Tibet-III experimental data from May 2009 through January 2010. The effective live time is calculated as 106.05 days. The results show that the description of transverse momentum, inelastic cross-section and inelasticity for the 4 hadronic interaction models is consistent with YAC-I experimental data within 15% systematic errors range in the forward region below 100 TeV. Among them, the EPOS-LHC model is the best hadronic interaction model. Furthermore, we find that the H4a composition model is the best one below the 100 TeV energy region.
