Flash Flood in Pula

Published: 11 May 2011

The case study shows that the flash floods in Pula were the result of a convective system which developed in the convergence zone caused by a specific placing of two Mediterranean cyclones. Generally, the Mediterranean region is recognized as one of the most cyclogenetic regions in the world. Mediterranean cyclones are classified in 3 major types: Genoa cyclones, Adriatic cyclones and non-Genoa cyclones. Although it is rather rare, the major-type cyclones can exist simultaneously belonging to the theoretical category of twin or eyeglass cyclones. The most common twins are the simultaneous Genoa and Adriatic cyclones (Brzovic, 1999), therefore classified as the 4th type of Mediterranean cyclones. Depending of the season and general synoptic conditions, the paths of the cyclones in the Mediterranean basin are diverse. On their way through this complex geography, they can produce a range of extreme weather phenomena such as heavy orographic precipitation, thunderstorms, supercells and mesoscale convective systems.
