Abstract: This paper analyses and characterizes snowfall events in one of the hottest, most arid areas in continental Europe. Our information was taken from a snowfall database that was partly our own, covering a period of over 100 years. The FLEXTRA model of air-mass back-trajectories was applied together with our own subjective synoptic classification. Data from the ECMWF Reanalysis of the 20th Century (ERA20C) were used for the calculation and clustering of the back-trajectories and the establishment of synoptic weather types. The snowfall events were classified into 8 synoptic types and 4 first-level and 8 second-level back-trajectories. The meteorological scenario for these extreme events was marked by mixed structures at altitude with a main NE/SW axis and dipoles on the surface dominated by powerful North Atlantic anticyclones and back-trajectories from the NE at the three levels analysed (500, 1500 and 5000 m.a.s.l.).
