In this study, we consider a 4-th order (1+1)-dimensional PDE called Zoomeron equation. Some conservation laws are derived based on direct method. We also derived some similarity solutions using the symmetries.
In the present work we study the unique solvability of local boundary value problems
with generalized gluing conditions for the third order differential equation with a loaded
parabolic-hyperbolic operator.
We describe a large-scale geodynamo model based on hypothesis about 6-jet convection in the Earth’s core. This hypothesis suggests indirect data of inhomogeneities in the density of the Earth’s core. The convection pattern is associated with a spherical harmonic Y24 which defines the basic poloidal component of velocity. The model takes into account the feedback effect of the magnetic field on convection. It was ascertained that the model contains stable regimes of field generation with reversals. The velocity of convection and the dipole component of the magnetic field are similar to the observed ones.
We represent conditions of hydrodynamic system when it passes the Painleve test. We
use Kovaleskaya-Gambie method for fourth order ordinary differential system. We obtain Lorenz-like dynamic, hydrodynamic system.
The paper presents our software system for estimation the degree of disturbance of the geomagnetic field. The system automatically classifies registered geomagnetic data and determines the state of the geomagnetic field for the current day. The results of approbation of the system showed the prospect of its application in problems of estimation and prediction of space weather. The system allows us to allocate weak disturbances of the geomagnetic field, which may occur before strong magnetic storms.
We performed analysis of the cosmic rays variations and studied features of geomagnetic field variations during periods of increased solar activity. The paper applies a new methods of modeling and analysis of the data developed by the authors based on wavelet transform and neuron networks. In this paper we allocated anomalous changes in cosmic rays that occurred some hours before geomagnetic storms.
Statistics of occurrence of anomalous disturbances in high-frequency geoacoutic emis-sion of the near surface sedimentary rocks and in atmospheric electric field by the ground surface before earthquakes is presented. Long-term continuous series of measure-ments of geoacoustic emission for the period of 2003-2012 at «Mikizha» site and the data of measurements of atmospheric electric field obtained for the summer-autumn periods of 2006-2008 at «Mikizha» site and for 2009-2012 at «Karymshina» site were used in the analysis. Anomalous disturbances of the emission and of the field were compared with the earthquake catalogue of Kamchatka Branch of Geophysical Service RAS.
Fundamentally new model of the shock wave (SW) generation in atmosphere and ionosphere during earthquake is proposed. The model proceeds from the idea of cooperative shock water crystallization in a cloud
The possibility of joint perturbation of geoacoustic, emanation and atmospheric electric
fields by the earth’s crust — atmosphere boundary before an earthquake is considered.
Secular changes of the lithospheric electric conductivity were analyzed based on the monitoring data of the Earth’s electric field over the period from 2001 to 2014. Those measures were carried out in Verchniya Paratunka, Tundroviy, and Shipunskiy that are located alongside the coastline of the Avacha Bay of Kamchatka and where the catastrophic earthquake is to be expected according the long-term forecast. It is noticed that the changes in behavior of the secular movements of the lithospheric electric conductivity sannual average values represented with changes at along and transverse directions of the seismic focal zone extension. A great many of such changes were detected on the Shipunskiy peninsula.
The results of investigations of the deformation process in the near surface sedimentary rocks, which has been carried out in a seismically active region of Kamchatka peninsular since 2007,are presented. The peculiarity of the experiments on the registration of geodeformations is the application of a laser deformograph-interferometer constructed according to the Michelson interferometer scheme.
The physical terms of origin and distribution of electromagnetic radiation of litospheric origin and features of registration based on them are examined. Measuring methods offer seismoelectromagnetic activity is parameters and procedures of their measuring
The results of continuous measuring of vertical gradient of AEF potential by CS110 during a few months are presented. The comparison of CS110 and ”Pole-2” are performed.
The analysis of results of experimental investigation concerning the influence of natural and technogenic events on radioactive gas and aerosols dynamics as well as structure and dynamics of different types of ionizing radiation in soil and ground atmosphere was performed. The results of the analysis were used to carry out of classification of revealed radiation tracersindicators of dangerous natural and technogenic phenomena. The algorithm of monitoring of optimum set of radiation tracers-indicators, which are measured simultaneously, of dangerous phenomena was developed. This algorithm uses the “2+1” rule for determining the optimum set of radiation tracers-indicators.
