This paper discusses the laminae characteristics in vertical profiles of ozone concentrations at three locations representing the Central (Praha, Czech Republic), Eastern (Legionowo, Poland) and Southeastern (Ankara, Turkey) parts of Europe. The total 785 soundings of January 1994-October 2003 with varied periods were analysed. We found that the lamination is frequent in winter and spring in these locations. The mean magnitude and depth of the laminae in these stations varied depending on the latitudes of the locations. Additionally, in order to understand the influence of tropopause heights on the laminae structure, the number of laminae was grouped according to the high and low tropopause heights. The frequency of laminae for both lower and higher tropopause groups for winter and spring seasons are close to each other.
