This poster deals with the behavior of annual cycle of total ozone (ACO3) in the latitudinal belt from 20° N to 60° N. The prominent feature of the spatial ACO3 spatial pattern is a sharp maximum over the north- east coast of Asia. In the middle latitudes the values of ACO3 correlate predominantly with the values of annual maxima of total ozone while in the lower latitudes there is a strong correlation with the values of ACO3 minima. Regarding temporal evolution of ACO3 we detected distinct negative trend in the period of 1979-1995 which is caused by the stronger negative trend of maxima than the negative trend of minima in ACO3. In the period 1995-2008 we found positive trend of ACO3 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 ACO3 was identified and linked to weaker positive trend of maxima than positive trend of minima in ACO3.
