ABSTRACT. The blizzard phenomenon in southwestern Romania. The most common situation when blizzard occurs in this region is when the East-European anticyclon’s ridge and a mediterranean low pressure field are coupled. Very rarrely the blizzard occures due to the atmospheric coupling between Azores anticyclone with a low pressure field. In this paper these posibillities of blizzard’s occurrence are studied. Their specific elements were compared in order to help operational activity of weather forecasters. For establishing the synoptic and mesoscale contexts that had generated the severe weather events listed below, global numerical model output -ECMWF (European Centre for Mediumum-Range Weather Forecast) and short-range numerical model output - ALADIN, EUMETSAT satellite imagies, maps using data from ESTOFEX site and observational data from meteorological stations, validated and administrated by National Meteorological Administration were used.
