Аннотация:It is argued that the negative total ozone trend in Western Europe which has been particularly strong in recent years can be related to a marked increase in values of some parameters of the Azores High at the sea level namely, atmospheric pressure p in its centre and its geographical latitude phi. A tentative conclusion has been drawn concerning the centennial variations of these parameters (with a period of about 80 years) approximately out-of-phase with the solar activity variations. If this is the case, parameters p and phi at the present time are near their maximum values and in the nearest years the total ozone tendency in Western Europe should change its sign. A relationship between parameters p and phi, and the 11-year cycle and QBO is also confirmed which is in accordance with the total ozone variations in Europe the same periods.
