Abstract
The conditions of formation of spring ozone anomalies in the Arctic and Antarctic are compared. It is shown that the distinction between polar ozone anomalies is due to a significant difference in the velocity and stability of the southern and northern polar vortices, as well as to the Antarctica’s Mount Erebus volcano, which is the powerful source of HCl. The paper describes the nature of its volcanogenic activity and the mechanism of the volcanogenic gas emissions transport to the Antarctic stratosphere.
