Total ozone response to major geomagnetic storms during non-winter period

Summary This paper is a continuation of the recent studies of ozone response to major geomagnetic storms, now for the non-winter period. No significant response was found under different solar cycle/QBO conditions due to a rather homogeneous distribution of ozone during this period. Nevertheless, locations of the largest ozone variability are the same as the centers of meteorological activity and closely related to the centers of quasi-persistent extremes in the geographical distribution of total ozone along latitudinal circle 50 N.
