摘要：The paper analyzes the synoptic conditions that have caused blizzard in Romania in the period January 21-23, 2011. The analyzed situation shows that especially in the east and southeast the phenomenon of blizzard can occur also in conditions initially nonspecific that later can evolve to situations specific to blizzard. Therefore in the winter the emergence and development of a Mediterranean cyclone and its circulation across the Balkan Peninsula, in interaction with an anticyclonic field can be an important signal that the blizzard will take place in Romania. The blizzard phenomenon is particularly dangerous for the road traffic, because by blocking the roads and the vehicles in traffic it can cause human deaths, but also it is an important risk factor for the other economic activities. The paper is useful for climatologists, meteorologists, master students and students and to a wide range of specialists interested in Romania`s climatic conditions during winter. The analysis on the blizzard of the period january 21-23, 2011 in Romania is a continuation of the extended studies of the regional climate variability (Bogdan, Marinică, Andreea Floriana Marinică, 2010, Marinică 2006 )
