| description | Episodes of NNW-erly windstorms, known in the area of Balkan Peninsula as Vardaris, were identified, with the aid of wind archive data, from the Regional Meteorological Centre of Makedonia of the Hellenic National Meteorological Service of Greece. The study of the seasonal, interannual, and diurnal variations of the occurrence of Vardaris windstorms, as well as their intensity, shows that it is a severe, long-lasting, and mainly winter-time feature, usually commencing in the morning hours. Preliminary results of the study of dynamic features accompanying Vardaris have shown that these windstorms are almost totally associated with cold fronts coming from northern sectors. The presence of a northerly jet or a tropopause fold aloft contributes to increases in the intensity or duration of the windstorms. The connection of Vardaris with these dynamical features implies that the observed negative (positive) trends of the occurrence frequency/duration (intensity) of Vardaris windstorms is in accord with the scenario of climate change. |
