Why do blizzards, heavy snowfalls prevail in southern and eastern Romania? Rare phenomenon at the Black Sea

The freezing cold that has seized Romania in the past week is here to stay, at least for the upcoming days. Weather forecasters say that temperatures have already climbed down to minus 30-Celsius degrees, and there are more heavy snowfalls and blizzard announced as of tonight. Almost the entire country is under the Code Orange alert for frost.

However, the most affected regions are the southern and eastern ones. And these regions are seldom hit by blizzards and heavy snowfalls. Meteorologists explained why these areas of the country are prone to lure extreme winter phenomena.

“In southeastern country there are several conditions for that, the first is given by the geography itself, we have the Carpathians as a dynamic barrier and the Black Sea as a thermic barrier. Between these two the cold air coming from the north is channeled and is getting stronger in the Carpathians’ curvature area. Besides, this cold air meets a warmer, moist air-mass, once the cyclones generated in the Black Sea are moving, and in serious situations the cold air reaches the Black Sea region, thrives with steam and brings large quantities of falls,” meteorologist Meda Andrei told Digi 24.

The Black Sea boiling

Moreover the frost brought another curious phenomenon in southeastern country, namely in the Black Sea area. These days, the sea was seen boiling at minus 14-Celsius degrees. Despite freezing cold, the Black Sea’s waves seemed to release water vapours, a unique phenomenon which can be seen once in several years. The sea boiling is caused by the temperature difference between the seawater and the outside.mare_46983400

Experts say that the phenomenon is called “dew fog” and is very rare.

“Last week the water temperature was very high for this time of the year climbing to 3.9 Celsius degrees, but now it climbed down to 0 or below zero and this explains this normal phenomenon, yet so rare on the Romanian Black Sea coast,” said Simion Nicolaev, manager of the Research Institute in Constanta.
