Abstract

An episode of low ozone values over Central Europe on November 29 2000 was observed at some Italian Brewer stations. Middle latitudes ozone variability, at time scales of 1-3 days, depends mainly on the atmospheric motions transport. This paper reports an investigation on synoptic scale ozone components, based on the O₃ tendency equations for determining the dynamic cause of the episode. Ultraviolet (UV) irradiance variations are also analyzed in order to find out how the weather patterns may lead to enhanced levels of UV radiation within few days.
