摘要：Explosive cyclogenesis over the south-eastern Romania december 2-3, 2012 . This paper is devoted to the study of the synoptic- dynamical conditions that contributed to the development of an rare explosive cyclogenesis event occurred at the beginning of 2012-2013 winter in southwestern Romania, more precisely between 2nd and 3th of December, 2012. The minimum pressure observed was 980,2 hPa, the lowest ever observed record in the surface of Sulina observation station, and also over the western side of Black Sea during period 1961-2000 and 1965-2004. It was found that the cyclone was not a regular one, but a real „meteorological bomb” one where the central pressure at sea level has recorded an important decrease at about 32,3 hPa in 24 hours, equivalent with 1,7 Bergeron. Comparative by „XX century storms” Lothar and Martin (level 2 and 1 on hurricane scale) which desolated western and central Europe in December 1999, this case of explosive cyclogenesis can be considered one of the extreme for our area concerning both meteorological view as well as the effects
