The problems of studying the interaction of conjugate geophysical wave fields of different nature, arising
from natural and man-made sources simultaneously in different environments: seismic in the lithosphere,
acoustic in the atmosphere, hydroacoustic in the hydrosphere, optical, meteorological in the atmosphere are
considered. The solution of the problems under consideration is due to the urgent problems of environmental
monitoring in connection with noise pollution by various types of transport, industrial and natural sources. As
a result, geoecological risks are generated that affect the social environment, first of all, on humans, as well as
on buildings. Multivariate numerical models of interwave interactions and their mechanisms are presented
and analyzed. As a result of interactions, various physical effects are generated that determine the degree of
influence of conjugate wave fields on the medium. On the basis of numerical modeling and the results of field
experiments, estimates of increased geoecological risks are given.

Modeling of the Sun's magnetic field from the kinematics point of view-the gravitational ion dynamo model

The first of a large number of works on the generation of the magnetic field of the Sun (MPS) and planets
is considered to be the work (Lehrmor 1920), which discusses the need to introduce a self-excitation mecha-
nism to amplify a weak electron current and obtain a strong MPC. In many subsequent works, models of self-
excitation of an electronic current are investigated. In the previous [1] and this paper, the current generating
the MPC is the motion of a positively charged liquid or gas. It is known that the current density is proportional
to the charge density and the velocity of their movement. According to the known estimates of the parame-
ters of the structure of the Sun the calculated charge densities and currents create magnetic fields (MP) for
seven of the top layers of the Sun: chronosphere, chromosphere, photosphere and four layers of the convec-
tive zone. The maximum permissible estimates of currents and MPS are obtained. From these estimates of the
kinematics-gravitational ion dynamo model, it follows that all layers of the model, taking into account certain
restrictions, can participate in the generation of MPS.
