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 F_10.7 and the planetary index of geomagnetic activity A_p for different phases of soalr cycel and for different seasons. Some nuermical estiamtes of the connection of TOC with the indices F_10.7 and A_p 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.
