Abstract:
The work presents a comparative study between two different synoptic situations generating of violent blizzards in 2010 February in Romania, with devastating social and economic effects. In the first case (the February 6-9 blizzard) we had a classic blizzard, but persistent in duration. The synoptic background was generated by the fourth type blizzard and its consequences were moderate precipitations quantities (10-25 l/mp) and moderate wind (maximum gust 18 m/s). The NMA issued an orange code for blizzard. The second case (February 10-11) was a violent blizzard, but shorter than the first, and it was generated by a very active Mediterranean cyclonic nucleus. Moderate amounts of snow fell, but, because of the violent wind (sustained enhancements 20-24 m/s), several snow-drift formed. The NMA issued only a yellow code for this blizzard. Both cases were complex, spectacular and their calamitous potential is undeniable. The first blizzard emphasized by its persistence (almost 54 hours), which leaded to the worsening situation, while during the second case the situation worsen because of the unusually high intensity of the wind (although its duration was shorter, about 18 hours).The results and the conclusions of the work may constitute a support in forecast activity for all forecasters.
