We describe a low-mode dynamo model. This model implements the various known regimes of cosmic dynamo systems, in particular, the various regimes of reversals. The source of regular reversals in the model is its internal dynamics. Violation of this cyclicality, transition to the chaotic regime of reversals are caused by fluctuations of the parameters, that are interpreted as the result of spontaneous coherent addition of the higher modes. The simplicity of the model allows you to easily modify it for various celestial bodies.

To investigate high frequency geoacoustic emission, a receiving system based on a compound vector receiver was installed in Kamchatka. It allows the authors to determine the direction of sound wave arrival. In the result of the data analysis for the period from August 2008 to January 2016, it was determined that geoacoustic emission directivity anomalies occur during the majority of the earthquakes with Ks >9.0 in the South of Kamchatka.

Statistical estimates of the effect in the electric field of the surface layer of the atmosphere parameters, such as time of the beginning, time of a maximum, its intensity and duration, were obtained. It was shown experimentally that the diurnal variation maximum of atmospheric electric field intensity is associated with air temperature height distribution. Power spectra of time variations of electric field intensity in the near ground atmosphere and of the horizontal component of geomagnetic field were under study. It was shown that there are oscillations with the periods of T _ 2, 0–2,5 hours in the power spectra of these parameters during a day. A possible mechanism of generation of these oscillations was proposed. It is associated with vortex motion of convective cells arising during the sunrise in the atmosphere exchange layer.

The data obtained by the World Wide Lightning Location Network (WWLLN) in the territory of Zabaykal’e are compared with the data received by the equipment for observations of Earth’s natural pulse electromagnetic field installed in Buryatia. Diurnal and seasonal dependence of lightning strokes observed in Zabaikal’e territory were obtained. It was shown that the maxima in diurnal variation registered by the instrumentation in Buryatiya coincide with the main world lightning sources.
