A strong cold spell is coming.
In addition to plummeting temperatures.
There is also the freezing rain that should not be underestimated.
Why is freezing rain scary?
How can we prevent this?
Let's take a look. Freezing rain, dripping into ice.
The freezing rain looks like it's rain.
But the temperature of the raindrops is less than 0
for supercooled water droplets.
Landing near the ground very cold power lines, trees.
house as well as on the ground.
Freeze into ice immediately.
Minutes give everything you come into contact with.
Put on a layer of "ice clothing".
Freezing rain is a peculiar natural phenomenon.
It mostly occurs in winter and early spring.
Grass and trees are frozen" and "crystal pulp".
It's all right.
What's so scary about freezing rain?
Formed by freezing rain.
Rime landscape. It's like a romantic fairy tale.
But it's the real body of catastrophic weather.
Not to be underestimated. 1.A large amount of freezing rain froze into ice on the power lines, causing the wires to snap and even pull down the power poles, disrupting communications and power transmission.
2.When the aircraft passes through the supercooled water droplet clouds, the wings and propellers will accumulate water and ice, which will affect the aerodynamic performance of the aircraft and cause the risk of flight accidents.
3.A large amount of freezing rain freezes into ice on the road surface, resulting in slippery road surfaces and traffic accidents are very likely to occur.
4.Freezing rain forms a large number of ice hangings under the eaves, and when the ice hangers fall, injuries can occur.
Angels look like the frozen rain of a demonic heart.
How can I prevent it?
The freezing rain fell into ice, and the destructive power was amazing.
How to protect against freezing rain?
Here are five practical guides.
1.Warm and non-slip N-piece set, quick arrangement.
Wear more! Try not to show your ears, hands and feet, which are prone to frostbite. If you want to go out without falling, it's best to wear non-slip shoes.
2.Freezing rain is threatening, stay away from them.
Freezing rain will freeze into ice on power lines, and the weight of the ice itself, combined with the effect of the wind, can easily strain the power lines and even pull down the power poles. Therefore, when we travel, we must stay away from telephone poles, trees, and eaves with ice hanging.
3.Traveling by car, carefully "slippery".
Freezing rain falls into ice, and traffic will be blocked due to the freezing of the ground, increasing the chance of traffic accidents. Therefore, regardless of whether you are a novice or an old driver, remember four words when driving: slow down and drive slowly! Do not overtake, accelerate sharply, make sharp turns or brake suddenly, and install tire chains if necessary.
4.Long distances, plan well.
Freezing rain can easily cause the railroad tracks, waterways, and aircraft engines to freeze, causing delays in trains and planes. Friends who travel long distances must plan well in advance, it is best to avoid the strongest period of rain and snow, avoid places with heavy freezing rain, pay attention to the weather and road traffic information along the way, and pay attention to safety.
5.When rain or snow block the road, it is better to rest and rest before setting off.
Rain, snow and freezing weather will affect road traffic, in case of road closures, traffic jams and other emergencies, follow the command of the on-site traffic police, on the spot or go to the nearest service station to wait for the road to be restored, if necessary, change the alternate route.
