Freezing rain in the last day in central Russia was not observed in the region freezing precipitation, said in an interview with RIA Novosti chief situational center Roshydromet Yuri Varakin.
"It was not freezing rain, it was freezing precipitation, rain, sleet, wet snow and rain and cereal was. Freezing precipitation occur in the border state between liquid and solid phase, but it was not freezing rain. If it was ice rain, we would have "fabulous" trees "- said Varakin.
As explained by the meteorologist, freezing precipitation observed when the atmosphere is formed "sandwich" — a layer of warm air is between two layers of cold. In this case, the snow, passing through a layer of warm, melting, turns to rain, and then re-enters the cold air.
"If you have time drop of rain covered with ice shell, it is freezing rain, but if the drops have time to reach the earth's surface is not covered with ice, it is called freezing precipitation," — he explained.
In both cases, the ice is formed, the degree of risk depends on the thickness of the ice layer. Black ice is dangerous phenomenon, when the ice thickness is 20 mm.
