Freezing rain - that's something new. It looks very nice, of course, but it's not good. A lot of wires were torn in Moscow. Airports Domodedovo and Sheremetevo were closed. About 100,000 people in Moscow region were left without electricity, water or heating.
And the fact that fallen trees are lying everywhere... Thousands trees fell over under the weight of ice. It's terribly.



Freezing rain is called the rain that falls when surface temperature is below freezing. Unlike sleet, a mixture of rain and snow that forms ice pellets, or hail, freezing rain is made entirely of liquid droplets. The raindrops become supercooled while passing through a sub-freezing layer of air hundreds of meters above the ground, and then freeze upon impact with any surface they encounter, including the trees, ground, automobiles, and electrical wires. The resulting ice, called glaze, can accumulate to a thickness of several centimeters and cover all exposed surfaces.
Freezing rain often causes major power outages by forming glaze ice. When the freezing rain or drizzle is light and not prolonged, the ice formed is thin. When large quantities accumulate, however, it is one of the most dangerous types of winter hazard. When the ice layer exceeds approximately 6.4 mm (0.25 in), tree limbs with branches heavily coated in ice can break off under the enormous weight and fall onto power lines. Windy conditions and lightning will exacerbate the damage. Power lines coated with ice become extremely heavy, causing support poles, insulators and lines to break. The ice that forms on roadways makes vehicle travel dangerous. Unlike snow, wet ice provides almost no traction, and vehicles will slide even on gentle slopes. Because freezing rain does not hit the ground as an ice pellet (called "sleet") but still as a rain droplet, it conforms to the shape of the ground, or object such as a tree branch or car. This makes one thick layer of ice, often called "glaze".
Freezing rain is considered to be an extreme hazard to aircraft, as it causes very rapid structural icing. Most helicopters and small airplanes lack the necessary deicing equipment to fly in freezing rain of any intensity, and heavy freezing rain can overwhelm even the most sophisticated deicing systems on large airplanes.
