Abstract
The analysis of the created distribution maps of the geomagnetic field and the atmosphere characteristics allowed us to developed a model that adequately explains the changes in the current Antarctic temperature – simultaneous “heating” in the west and “cooling” in the center and in the east. It is a chain of cause-effect relationships: the geomagnetic field – the flux of solar protons – the concentration of ozone – the temperature and humidity near the tropopause – the surface temperature. The reduced intensity of the geomagnetic field in the Western Antarctica results in a systematically low concentration of ozone and increased humidity on the tropopause, which facilitates the retention of long-wave radiation from the Earth in the troposphere due to the greenhouse effect and an increase of the surface temperature. The increased intensity of the geomagnetic field and ozone concentration in the Central and Eastern Antarctica cause an increase in temperature and a decrease in humidity at the level of the tropopause, which does not prevent the penetration of long-wave radiation from the Earth upwards and causes cooling of the lower troposphere. Taking into account the geomagnetic field as a factor of influence on the climate allows us to adequately explain the found differences in Western and Eastern Antarctica.
