Paper Abstract

The connection of total ozone content (TOC) with helio-geomagnetic activity in the mid-latitude atmosphere was considered. The study wused measurements from the Nimbus-7 satellite (TOMS) covering the time interval 1978-1992 for three regions: Irkutsk (Russia), Collm (Germany), and Saskatoon (Canada). An analysis was made of the dependence of TOC variations on the solar radio flux inteisty F10.7 and the planetary index of geomagnetic activity Ap for different phases of soalr cycel and for different seasons. Some nuermical estiamtes of the connection of TOC with the indices F10.7 and Ap were obtained. Non-zonality effects in the character of the dependence of totalozone content on helio-geomagnetic activity were identified, which seem to be associated with climatological differences of the regions under consideration.
