What is Freezing Rain?
Freezing rain is composed of supercooled water droplets, which are precipitation phenomena that quickly freeze into ice when raindrops encounter objects with temperatures below zero degrees Celsius during landing, such as power poles, trees, vegetation, road surfaces, etc.
The process of formation of freezing rain
The formation of freezing rain requires a special atmospheric stratification, a bit like a sandwich or a sandwich, and the distribution of the atmosphere from top to bottom is a "cold-warm-cold" state.
The "permanent place" of freezing rain
The "footprints" of freezing rain are all over the north and south of the river, and the three northeastern provinces, Shandong, Hebei, Shaanxi, Gansu, Guizhou, Sichuan, Jiangxi, Hubei, Hunan and other places have its "figure".
Freezing rain usually occurs in early winter or late winter and early spring, with more in the south than in the north, more in mountains than in plains, and more in higher altitudes than in valleys.
Throughout the country, the place with the highest "appearance rate" of freezing rain is Guizhou. Guizhou has many rainy days, high terrain and abundant water vapor, often forming a "cold-warm-cold" sandwich layer, which is a humid climate environment that freezing rain likes. Weining, Guizhou, is known as the "Land of Freezing Rain".The average number of freezing rain days per year can reach 42 days, and the thickest freezing rain has reached 40 mm.
Freezing Rain's "superpowers".
Freezing rain is a highly destructive meteorological disaster, rightTransportation, agricultural production, power and communicationand so on.
Freezing rain with such destructive power
How can we prevent this?
1.Personal life:
The public should try to go out as much as possible, and if they need to go out, they should take cold and anti-slip measures, and pedestrians should pay special attention to avoiding motor vehicles.
2.In terms of transportation:
Drivers should slow down, do not overtake, accelerate sharply, turn sharply or brake urgently, and install tire chains in time if necessary.
The ice on the highway should be melted in time to remove the ice on the road to avoid traffic accidents.
Airports should clean up the runway and ice accumulation on the aircraft in a timely manner, install de-icing equipment on the aircraft or fly around freezing rain areas.
3.Power Communications:
Remove the ice on the wires in time, or start the ice melting technology.
4.Agriculture:
timely overhaul and strengthen vegetable greenhouses, livestock and poultry enclosures; Clean up the ice in time, regulate the temperature and humidity, and enhance the thermal insulation and cold resistance of the facility.
