ASSOCIATION OF THE LAMINATED VERTICAL OZONE STRUCTURE WITH THE LOWER-STRATOSPHERIC CIRCULATION

In this study the examination of the role of the atmospheric circulati on in the lower stratosphere in relation to the laminated structure of ozone in the subtropical atmosphere is attempted. This analysis is ba sed on the vertical ozone profile data collected by balloon-borne sond es released at Athens, Greece (38-degrees-N, 24-degrees-E). From Strat ospheric Ozone Experiment (EASOE) and the Tropospheric Ozone Research (TOR), it is shown that the lamination phenomenon in ozone profiles, e specially in the lower stratosphere, was very frequently present. Furt hermore, a characteristic minimum of ozone partial pressure at the hei ght region of 14-17 km has also been detected. The occurrence of the l aminated ozone structure as well as the appearance or the characterist ic ozone minimum, correlated with the general circulation, leads to th e following results: (a) The laminated ozone profiles are associated w ith the north-northwest circulation in the lower stratosphere; and (b) the characteristic ozone minimum is related to the influence of the s ubtropical jet stream circulation.
