Calculations were performed on the methodological bases presented in Part 1 and the results are shown in this part It was found that for Thessaloniki, Szeged and Helsinki, clusters of the trajectory positions originating from North Africa and/or the Sahara are strongly associated with the highest PMio episodes, though with a different frequency. Furthermore, two statistical indices were used to estimate PMio exceedances for the clusters retained for each city.
