Freezing rain at what temperature. Freezing rain in Russian cities
Freezing rain - atmospheric precipitation in the form of transparent ice balls with a diameter of 1-3 millimeters. Inside these balls is unfrozen water. Freezing rain is formed in the case of a temperature inversion - a reverse, anomalous temperature distribution. As a rule, with increasing altitude, the air becomes colder, but in the zone of passage of warm atmospheric fronts, it sometimes happens that cold air accumulates in the surface layers, and warmer air masses are located above it. Raindrops falling from warm clouds, flying through a layer with a negative temperature, turn into ice balls with water inside. Colliding when falling with a hard surface, these balls are broken into shells. At the same time, water flows out, forming a beautiful, but dangerous ice crust. Freezing rain increases injuries, increases the number of road accidents. They destroy trees that break under the weight of icy branches,
deprive animals and birds of food. This natural phenomenon cuts off electrical wires and paralyzes vehicles, turning them into blocks of ice.
In Russia, freezing rain is most often observed in the Southern, Volga, Central federal districts, as well as in the Leningrad, Pskov, Novgorod regions. Many people remember the freezing rain that occurred in the Moscow region on December 26, 2010. The ice shell that covered everything around then reached a thickness of three centimeters. More than 50 thousand trees died. This natural disaster caused numerous power line breaks and led to a transport collapse - due to icing
I had to change the schedule, and the work of Domodedovo Airport was completely stopped. More than 400 thousand people were temporarily left without electric lighting. The damage from this freezing rain amounted to more than 200 billion rubles. At the end of November 2012, freezing rain hit the Moscow region again, causing damage to transport and power lines. Cars and green spaces were again damaged. But the damage at that time was less - the fact that the freezing rain happened in the daytime against the backdrop of a thaw affected, so its consequences were not devastating. However, meteorologists do not consider freezing rain to be common. Rather, these are natural anomalies that do not happen very often. And yet it is worth knowing how to prepare for them, and how to deal with their consequences.
During and immediately after freezing rain, of course, it is best to stay at home. But if you still need to go outside, try to be extremely careful, avoid especially slippery places and do not make sudden movements.
During freezing rain, try to protect your face and hands so that the sharp edges of the frozen drops do not damage exposed skin. It is better to leave the car in the parking lot and, if possible, use public transport. But if you do have to get behind the wheel, drive as carefully as possible, avoid sudden braking, reduce maneuvering to a minimum and observe an increased interval. To free a frozen car
from the ice crust, use a heating pad with hot water. To open a frozen door, gently rock it until the ice cracks at the joint. Warm up the car, clean the glass with a scraper and go to the car wash, where the ice crust will be knocked down by the pressure of water. Recall that on Monday evening, November 7, freezing rain again covered Moscow and the Moscow region. The streets and trees were covered with a thin, shiny crust, and car owners had to free their cars from glass captivity. In addition, freezing rain caused the trains "Lastochka" and "Sapsan" to stop - because of the icing of the wires, the trains could not move,
Life.ru reports. Meanwhile, weather forecasters warn that until December 20, the weather in the capital region will be unstable. Earlier, Director of the Hydrometeorological Center of Russia Roman Vilfand said that the average temperature in January will be -9.2. Such frosts are close to normal, but the winter will be much colder than last year. As Dni.Ru wrote, real winter will come to Moscow on November 11-12. Night temperature will drop to -10, during the day it is expected to -5 in the capital, to -8 in the region.
Falling out of the clouds at negative air temperatures (most often 0 ... -10 °, sometimes up to -15 °) in the form of transparent ice balls with a diameter of 1-3 mm. There is unfrozen water inside the balls - falling on objects, the balls break into shells, water flows out and ice forms.

An excerpt characterizing Freezing Rain
Princess Mary interrupted him.“Oh, that would be so awful…” she began, and without finishing from excitement, with a graceful movement (like everything she did in his presence), bowing her head and looking gratefully at him, she went after her aunt.
On the evening of that day, Nikolai did not go anywhere to visit and stayed at home in order to settle some accounts with the horse sellers. When he finished his business, it was already late to go somewhere, but it was still early to go to bed, and Nikolai walked up and down the room alone for a long time, pondering his life, which rarely happened to him.
Princess Mary made a good impression on him near Smolensk. The fact that he met her then in such special circumstances, and the fact that it was precisely her at one time that his mother pointed out to him as a rich party, made him pay special attention to her. In Voronezh, during his visit, the impression was not only pleasant, but strong. Nikolai was struck by the special, moral beauty that he noticed in her this time. However, he was about to leave, and it never occurred to him to regret that, leaving Voronezh, he was deprived of the opportunity to see the princess. But the current meeting with Princess Mary in the church (Nikolai felt this) sank deeper into his heart than he foresaw it, and deeper than he wished for his peace of mind. This pale, thin, sad face, this radiant look, these quiet, graceful movements, and most importantly, this deep and tender sadness, expressed in all her features, disturbed him and demanded his participation. In men, Rostov could not stand to see the expression of a higher, spiritual life (that's why he did not like Prince Andrei), he contemptuously called it philosophy, daydreaming; but in Princess Mary, it was in this sadness, which showed the whole depth of this spiritual world alien to Nicholas, that he felt an irresistible attraction.
“A wonderful girl must be! That's the angel! he said to himself. “Why am I not free, why did I hurry with Sonya?” And involuntarily he imagined a comparison between the two: poverty in one and wealth in the other of those spiritual gifts that Nicholas did not have and which therefore he valued so highly. He tried to imagine what it would be like if he were free. How would he propose to her and she would become his wife? No, he couldn't imagine it. He felt terrified, and no clear images presented themselves to him. With Sonya, he had long ago formed a future picture for himself, and all this was simple and clear, precisely because it was all invented, and he knew everything that was in Sonya; but with Princess Mary it was impossible to imagine a future life, because he did not understand her, but only loved her.

On Tuesday, February 9, freezing rain is expected in Moscow. This was reported by forecasters of the weather center "Phobos"
“This week will be marked by a lot of freezing rain. Precipitation will be of an insignificant, weak character, but it will be characterized by a periodic transition from a mixed phase to a freezing rain phase. Moreover, it can be on Tuesday, Wednesday, Thursday, Saturday, and especially strong - on Sunday evening, turning into Monday night, ”the forecaster of the center said.
What is freezing rain?
Freezing rain is an atmospheric phenomenon that occurs due to the difference in temperature at the height of the rain front and at the surface of the earth. It refers to the so-called "oversized" precipitation, which falls out monotonously over a fairly long period of time.
Everything happens like this: below, above the surface of the earth, there is cold air (ice rain traditionally falls at a temperature of -1 to -15 degrees Celsius), and above it is a layer of warmer air. Raindrops, approaching the ground, freeze very quickly - but only outside. It turns out that freezing rain consists of solid transparent balls of ice, inside of which unfrozen water remains.
When falling, the balls break, the liquid pours out and quickly freezes, forming ice on the asphalt and an ice crust on other surfaces (on tree branches, roofs of houses, cars, etc.).
Note! In the science of weather there is also such a thing as “rain showers” - but, unlike prolonged freezing rain, it refers to heavy rainfall, characterized by a sudden onset and a sharp change in intensity. It happens at positive temperatures and is dangerous because it sharply worsens visibility.
