This paper deals with the behavior of the annual cycle of total ozone (ACO3) and its amplitude (O3AMP) in the latitudinal belt from 20° N to 60° N. The prominent feature of the O3AMP spatial pattern is the sharp maximum over the north-east coast of Asia. Regarding temporal evolution of O3AMP we detected distinct negative trend in the period of 1979-1995 which is caused by stronger negative trend of maxima than the negative trend of minima in ACO3. In the period 1995-2008 we found the positive trend of ACO3 in most regions due to stronger positive trend of maxima than that of minima in ACO3 in the middle latitudes (especially over the central and northern Europe and the north-east Asia). In the lower latitudes a weak negative trend of O3AMP was identified and linked to weaker positive trend of maxima than positive trend of minima in ACO3. The behavior of the temporal trends was linked to the changes in Brewer-Dobson circulation and to the trends of tropopause pressure.
