The statistical mixture distribution used to approximate a windrose of a defined wind type

Warm, humid and strong wind in the Adriatic sea and coastal area, blowing mostly from southeast quadrant is known under name jugo, customarily considered as sirocco. This wind type can be extracted from the entire wind data, by the criteria considering wind direction and velocity intervals, as well as continuous duration above a defined time threshold. Applying so defined criteria the empirical wind rose related to jugo events for a site can be obtained. Such wind roses for three coastal stations were approximated by statistical mixture distribution and described by corresponding parameters. This enables quantitative, objective and simpler comparison of results obtained for several samples.
