Abstract The present paper proposes to highlight the evolution of the generating factors of the cold wave, which from February 25 to March 2, expanded from the northern and northeast of the European continent and affected much of it, including the Romanian geographic space. After a relatively warm winter as thermal aspect, with an ephemeral snow cover in the low relief areas, the last decade of February and the beginning of March, it creates the classic pattern for a genuine winter episode in Romania. Its location in the contact area between an anti-cyclonic field centered on northern and northeastern Europe and a cyclone in the south-east of the continent will facilitate in the first phase the transport of cold air. Then another factor climatic risk, was of interest, namely the blizzard, with the classic area of manifestation in the south, southeastern and eastern Romania. The thermobaric coupling made in this way ensures severe weather conditions, but normal for the cold season. Besides these triggering factors, it is important to mention the risks induced and associated with this severe weather episode, causing damage to agricultural crops, communication routes, to society in general and to the entire environment, affecting the quality of life as a whole. Special attention will be given to another phenomenon, which followed the cold wave, namely the freezing rain. The practical applicability of the study carried out in operative activity, as well as its actuality, consists in the fact that it is a useful support material, referring to an issue as alarming, as normal for the temperate climate zone during the cold season.
