摘要：

The total ozone response to strong major geomagnetic storms (A(p) greater than or equal to 60) in winter along the 50 degrees N latitudinal circle is studied. The results add to the recent results of Lastovicka et al. (1992) obtained for European middle latitudes (similar to 50 degrees N) and to the results of Mlch (1994). A significant response of total ozone is only observed in winter under high solar activity/E-phase of QBO conditions (E-max) and seems to be caused by geomagnetic storm-induced changes of atmospheric dynamics. There are two sectors along latitude 50 degrees N, which are sensitive to forcing by geomagnetic storms both in total ozone and the troposphere - north-eastern Atlantic-European and eastern Siberia-Aleutian sectors. The total ozone response under E-max conditions manifests itself mainly as a large decrease in the longitudinal variation of ozone after the storm, which means an increase of ozone in Europe. The observed effects in total ozone consist in redistribution, not production or loss of ozone.
