In near-polar region geomagnetic variations play active role to nonlinear tectonic processes and human health. This analysis is based on spatial-time spectral representation of geomagnetic variations and wave migration transformation. Many perturbations in electromagnetic fields may because by external factors (e.g. magnetic storms, ionosphere anomalies and other phenomena related to solar activity) “trigging” tectonic processes but having no direct relation to the processes of their preparation. Geophysical processes are responsible for perturbations in the Earth’s rotation and orientation on a wide range of time-scale, from less than a day of a millions of years. The geological structure of some sites of earth crust promotes occurrence of wave guides a number of geophysical fields (acoustic, seismic, electromagnetic), usually channels of transportation of acoustic, seismic, electromagnetic energy in earth crust are coincide spatially. Analysis of amplitude and phase of geomagnetic variations can give information on tectonic structures and state of environment. Geomagnetic variations are intrinsically a multiscale process time and space. One of the most important features of geomagnetic variations is multicyclic character, which predetermined both the extent and character of geomagnetic show, and specific features. Recently, there are collected many facts, shows the dependence between the processes in Earth bio-sphere, the elements of it, gelio- geo- physical and meteorological factors. The recent experimental data gives us the opportunity to conclude, that the geomagnetic and geoelectric fields produced the biological effect that is correlated with solar activity variations. The result of many years investigation of the geomagnetic variations on the near-polar territory, the authors found the facts of sharp increasing of intensity of the short wave’ variations near the points of fault-crossing. Analysis of character of geomagnetic variations can give information on the alleged effects of electromagnetic fields on human health.

The role of atmospheric pressure, and its interrelation with a condition of geological structure a poorly illustrated in the literature. Recently new factors appeared testifying to presence and variety of such relations. These are changes of hydrodeformation fields correlating with change of atmospheric pressure and, as a consequence change the underground water level; also a relation of microseism character in the crust with a change of pressure. The set the above parameters influence upon an intensity and a course of exogenous processes, and, hence, relief and landscape formation. According to results of research of atmospheric pressure along regional structures Arkhangelsk – Vologda – Moscow – Vologda - Archangelsk; Arkhangelsk – Cherepovec – Ribinsk – Moscow – Ribinsk – Cherepovec – Arkhangelsk regional minima are allocated in the North of the Russian Plate. These minima spatially coincide with cross of faults. Static atmospheric pressure minima between Velsk in Arkhangelsk region and Sokol in Vologda region (federal road M-8 Arkhangelsk – Moscow); between Pliseskaya and Konosha railway station (railway Arkhangelsk – Moscow) are clearly detected. Considering that in the area Velsk-Sokol an earthquake has been registered, it is possible to task about the modern activity of structure. Minima have complex structures with regional lowering and rise of pressure in the center (pressure difference up to 25 mb). It is similar to so called “eye of hurricane” structure. Such structure and presence of pressure gradients theoretically should provide the accelerated loss of atmospheric precipitation. The results received by of laboratory of ecological biology of INEP UB RAS serve as an acknowledgement assumption. According to laboratory researches high content of Pb has been registered in mosses collected near station Iles (7.91 mg/kg) and in Sphagnum mosses collected at the 48^th km of the road Arkhangelsk – Karpogori (6.81 mg/kg) (Tarkhanov, etc., 2004). An increase of Zn in green mosses (61.17-77.53mg/kg) was observed nearby Kholmogorskaya station. These areas spatially coincide with allocated static local atmospheric minima.
