Abstract. - Winter 2006-2007 in Oltenia compared with winter 2007-2008. The starting point of the paper was an american climatological report under which globally, the winter of 2006-2007 was the most warm from whole series of observations. Also, the National Administration of Meteorology has made in department of climatology a report which certifies that, namely, in our country the mean temperatures of January 2007 have exceeded the multiannual means in all country regions. Starting from these climatologically opinions, paper aims synoptic analysis at european scale and mezoscara of atmospheric circulation at different layers of the atmosphere. This analysis was motivated by abnormally warm weather in the winter of 2006-2007, especially in January, compared with the winter of 2007-2008. For this purpose, we have determined the main types of circulations that favored the thermal variations. Also, we analyzed the distribution of monthly precipitation amounts.
