The natural phenomenon, absent for 25 years, is recorded in Italy

Employees of the Miramar marine reserve in Trieste recorded the natural phenomenon that had not been seen in the area for 25 years.

Three days ago, a thin crust of ice formed below sea level in the wider area of ​​the Gulf of Trieste, reflecting the morning sunlight.

A similar phenomenon, on a larger scale, happened the last time in that area 25 years ago, on January 25, 1999, according to "Area Mrina Protetta Miramare".

Weather conditions then were similar to those recorded today. The area was affected by low temperatures reaching only a few degrees above zero and a solid anticyclone with very warm high-altitude air was developing.

Another factor in this phenomenon is that the sea is completely calm for days on end, which has the effect of turning that thin layer of fog into ice.
