Preliminary studies on the occurrence of local severe weather events in Friuli Venezia Giulia

In this work, the results obtained with the analysis of 3 years of data concerning the occurrence of local severe weather events (LSWE) in the plain of Friuli Venezia Giulia (FVG) are presented. These data are essentially collected by volunteers who personally observed the development of these phenomena or at least the damages produced by them. These data show that local severe weather events are much more frequent than previously expected just because of the occasional reports; moreover, they appear to be mainly associated to the approaching of a cold front over the Friuli region. The spatial distribution of these phenomena is not uniform, even if the study area is relatively small, but it is likely dependent from the interactions between synoptic perturbations and orography.
