February 9, 2013. The residents of the Russian capital will soon begin to shake the mere mention of ice. Before the events of December 2010, many do not even heard of, and now not only know but also regularly face.

Another thin layer of transparent ice, roll up everything — from cars to sidewalks — was the result of falling freezing precipitation at slabootritsatelnoy temperature. Since the past few days, Moscow and all of Central Russia is in a zone removal of warm and humid Mediterranean air, the sleet as no surprise to meteorologists. Adverse weather phenomenon appeared in the weather forecasts for a few more days. However, its intensity, as always, raised questions.

Physics of the phenomenon is quite simple. Warm, and therefore more light air trod on a wedge of cold. As a result, cloud layer which formed precipitation was warmer temperature reached 3, whereas it remained slabootritsatelnoy lots from ≥ 1 to ≥ 3 °. Precipitation occurred in the liquid phase in contact with a cold surface (expensive cars, trees, etc.), immediately cover the entire crust of ice.

In fact, weak sleet with the fallout of supercooled drizzle and light rain was observed over the past two days. But as the phenomenon was not intensive, no one except the meteorologists did not notice. However, on the night of Friday to Saturday from south-west came the new, more powerful wave of heat. It was preceded by a warm front in the area of which was supercooled rain. Rainfall was greater, so the intensity of the ice turned out great.

Morning many motorists began with a daunting task of opening doors and scraping ice from the car windows. By noon, the temperature passed through zero to positive values, and the ice began to break down. Recurrence of such events in the next 7-10 days is not expected.

Meanwhile, the ice took place not only in Moscow, but in the eight regions of Central, Southern and North-Western regions. On some sections of the route M2 ("Crimea") and M4 ("Don") at night there was a difficult road conditions. Glaze deposits on wires and trees were observed in the Bryansk, Kursk, Smolensk, Moscow and Tula regions. Day back in the Volgograd region of Kalmykia and the thickness of glaze deposits reached 16 mm.
