Freezing rain refers to what kind of weather conditions

What is freezing rain.

Rain in which raindrops collide with the ground, ground objects, airplanes, etc., and freeze immediately is called freezing rain. When this rain falls from the sky, it is a supercooled water droplet below 0°C, and when it hits a tree branch, power line, dead grass or other above-ground objects, it freezes into a smooth, crystal-clear layer of ice shell, sometimes freezing and dripping, like icicles. This type of ice is also known in meteorology as "rime".

Freezing rain mostly occurs in winter and early spring. Guizhou Province is the region with more freezing rain in China, followed by Hunan, Jiangxi, Hubei, Henan, Anhui, Jiangsu, Shandong, Hebei, Shaanxi, Gansu, southern Liaoning and other places, among which there are more mountainous areas than plains, and the most high mountains.

What's the harm in it.

Freezing rain is a catastrophic weather. It can crush power lines and ** lines after freezing and accumulating on ground objects, and severe freezing rain will collapse houses, crush trees, bamboo, and freeze crops and vegetables to death. Due to the freezing of the ground, it has a great impact on traffic.

Sound. Flying in a cloud of cooled water droplets can cause ice accumulation in the wings and propellers, causing crashes. In the late middle of January 1984, under the influence of strong cold air, freezing rain occurred in many areas of Guizhou, Hunan, Jiangxi, Hubei and other provinces, causing power lines to break and invert.

All the wires in Guizhou Province were interrupted, seriously affecting the communication work. The ice thickness of Hunan transmission lines is more than 20 mm, and some high-voltage lines are one.

Melting ice 5-6 times. Due to the impact of freezing weather, Guiyang Bus Station stopped 803 long-distance buses, and 418 rural buses were intermittently suspended. Several counties near Changsha, Hunan Province stopped 339 shuttle buses; Only Linwu and Zixing counties have broken off nearly 5 million bamboos and trees.

In Guizhou, 10 rapeseed that was mossed early was frost damaged.

Freezing rain, meteorologically also called rime, commonly known as ice. Meteorologically, it is called freezing rain because the rain that falls from the air is ice when it falls to the ground. We know that, in general, the higher you go, the lower the temperature, but in the event of freezing rain, the temperature near the ground is lower than the temperature at the sky, which is usually what we call the air inversion.

In this way, when the rain falls on the surface of an object with a temperature below 0, it quickly condenses into ice.

Freezing rain is a kind of disaster weather, which often causes power supply and communication interruptions, and is the focus of the meteorological department's serviceHow is the high temperature defined to determine the degree of summer heat, and the meteorological station usually uses the number of high temperature days, the duration of high temperature and the extreme maximum temperature to illustrate. Generally speaking, when the daily maximum temperature is higher than 35, it is called hot weather, and when the daily maximum temperature reaches more than 38, it is very hot weather. When it is expected that the daily maximum temperature will be above 35 for more than three consecutive days in the future, the meteorological station will issue a high temperature forecast to remind people to pay attention to heat stroke prevention and cooling.

Freezing rain is composed of supercooled water droplets, which freeze immediately when colliding with objects with a temperature below 0, raindrops below 0 can remain supercooled in the air with a temperature slightly below 0, and their appearance is the same as that of ordinary raindrops, and when it falls on an object with a temperature below 0, it immediately freezes into a smooth and transparent ice layer.

Most of the freezing rain occurred in more than a month from early January to early and mid-February, and the start date was early in the north and late in the south, early in the mountains and late in the plains, and the end date was the opposite. In the higher mountainous areas, the freezing rain starts early and ends late, and the freezing rain period is slightly longer. For example, at the Guangming Peak of Huangshan Mountain in southern Anhui, the freezing rain generally begins in early November and ends in early April of the following year, which lasts for 5 months.

When the strong cold air moves southward and encounters the warm and humid airflow, the cold air is inserted like a wedge below the warm air, causing the temperature near the surface to plummet below freezing, and the moist warm air is lifted to form cloud-induced rain. When raindrops fall from the sky, power poles, trees, vegetation and road surfaces are covered with a thin layer of crystal clear ice due to the temperature below 0°C near the ground, a meteorological phenomenon called "freezing rain".

When raindrops fall from the sky, a thin layer of crystal clear ice freezes on power poles, trees, vegetation and road surfaces due to the low temperature near the ground, which is called "freezing rain" in meteorology.

Hazards: After the wire freezes, it shrinks when it is cold, and it will break due to the weight of freezing rain. Sometimes, rows of power poles are pulled down, disrupting telecommunications and transmission. Road traffic has been hampered by icy ground, which has led to an increase in traffic accidents.

When the field freezes, it can freeze the winter wheat that has returned to green, or freeze the seedlings of crops sown in early spring. In addition, freezing rain can also destroy young forests and frostbitten fruit trees on a large scale. The thickness of freezing rain can generally reach 10 20 mm, and the thickest is 30 40 mm.

When freezing rain occurs, the wind is often stronger, so the impact of freezing rain on transportation, especially on communication and transmission lines, is greater. According to the analysis of meteorological experts, freezing rain is a precipitation phenomenon produced under a specific weather background. When the northwest and southwest airflows are strong, there is cold air intrusion on the ground, and there is a warm airflow northward over 1500 to 3000 meters, and the vertical structure of the atmosphere is cold at the top and warm in the middle, from top to bottom are ice crystal layer, warm layer and cold layer.

The temperature of freezing rain is generally below 0.

Freezing rain is made up of ice-water mixture.

Precipitation that freezes immediately after colliding with an object with a temperature below 0 is a disastrous weather seen in early winter or late winter and early spring. Raindrops below 0 remain supercooled in air with a temperature slightly below 0 and have the same appearance as normal raindrops.

Freezing rain mostly occurs in winter and early spring. Guizhou Province is the area with more freezing rain in China, followed by Hunan Province, Jiangxi Province, Hubei Province, Henan Province, Anhui Province, Jiangsu Province and Shandong Province, Hebei Province, Shaanxi Province, Gansu Province, Liaoning Province and other places, among which there are more mountainous areas than plains, and the most high mountains. When freezing rain accumulates to a certain extent, it is not only harmful, but also harmful.
