【 摘 要 】

A long-term regime of anomalies in total ozone in Baikal region in 1987-2016 was studied. The typification of synoptic processes of the formation of positive and negative anomalies of the total ozone content is proposed, which reflects the contribution of natural circulation processes. It is established that at present in Baikal region negative ozone anomalies prevail over positive anomalies. This can have a negative impact on the ecology of the region. The decrease in ozone is accompanied by an increase in the proportion of ultraviolet radiation, which is dangerous for ecosystems and human health.
