Peculiarities of the modern global warming

Abstract

The peculiarities of modern climate warming and the influence of global atmospheric circulation on it are considered from the position of solar-terrestrial relations. The role of the main atmospheric currents between the equator and both poles of the Earth is so great that for four decades it has caused unprecedentedly strong forest fires and other natural disasters which affected not only Siberia and Southern Europe (Spain, Portugal, France, Italy, Greece and others) but also the USA, Canada and Australia. Another phenomenon of the modern climate is a paradoxically high winter warming in the zone of the Siberian anticyclone. Due to intensification of meridian circulation since the last quarter of the 20th century, the increase in mean annual temperature at the cold pole of the Northern Hemisphere in Yakutia has twice exceeded indicators of other regions and dictates the course of warming of all Northern Asia and North America. The warming wave from the center of the Yakutian core has even reached the southern periphery of the anticyclone in the Northern Tien Shan. The practical side of the study concerns the actively developing oil and gas complex of Yakutia. In nearest future Yakutia will not leave the zone of dangerous forest fires. Along with the costs of extinguishing fires, additional expenses will be required here to deal with post-fire cryogenic transformations of the highly porous base soils. Atmospheric meridian circulation is too large-scale phenomenon to avoid it at the regional level. It amplifies the dynamics of all natural processes in both hemispheres of the Earth and is modulated only by the Sun’s activity in the course of its 11-year and hundred-year cycles.
