Episodes of high ozone concentration measured simultaneously (Buzzi et al., 1984) were associated with cyclogenesis in the western Mediterranean. A further study presented here shows that ozone detected at Mt Cimone was not the same origin as that observed by the Electra but had a separate episode of subsidence of the tropopause.

High values of ozone concentration were measured during one episode of cyclogenesis in the western Mediterranean as part of ALPEX (on April 25, 1982). The concentrations were found both in the mid-troposphere and at a station located on a mountaintop in the Apennines. It is shown that the ozone-rich air sampled in the troposphere originated in the lower stratosphere one day before, and had descended as a consequence of the cyclogenic episode. The interpretation of the other ozone concentration peak is more problematic, as conditions in the meteorological field of the observation posts were considered to be poorly defined.
