In addition to the sudden drop in temperature, the strong cold wave also brings freezing rain, which should not be underestimated. Why is freezing rain so terrible? What impact will it have on the Spring Festival travel rush? How can we prevent it? Let's watch the freezing rain, water turns into ice Freezing rain may look like rain, but the temperature of the raindrops is less than 0℃, which means they are supercooled water droplets. When they fall on cold wires, trees, houses and the ground near the ground, they immediately freeze into ice, covering everything they touch with a layer of "ice coat" in minutes. Freezing rain is a peculiar natural phenomenon that often occurs in winter and early spring. It can even cause "grass and trees to freeze" or "crystal patina". The rime landscape formed by freezing rain looks like a romantic fairy tale world, but its true nature as a disastrous weather should not be underestimated: 1. A large amount of freezing rain froze into ice on the power lines, causing the wires to break and even pulling down the poles, disrupting communications and power transmission. 2. When an aircraft passes through a layer of supercooled water droplets, water and ice will accumulate on the wings and propellers , affecting the aircraft's aerodynamic performance and posing the risk of a flight accident. 3. A large amount of freezing rain freezes into ice on the road surface, making the road slippery and very prone to traffic accidents. 4. Freezing rain forms a large amount of icicles under the eaves, and when the icicles fall, injuries may occur. Icicles (Source: Xinhuanet) How to prevent freezing rain? Freezing rain turns into ice when it hits the ground, which is extremely destructive. How to prevent freezing rain? Here are five practical guidelines for you ↓↓↓ 1. Warm and non-slip N-piece set, quickly arrange Wear more clothes! Try not to expose your ears, hands and feet, which are prone to frostbite. If you want to avoid falling when going out, it is best to wear non-slip shoes. 2. Freezing rain is coming, stay away from it Freezing rain will freeze into ice on the power lines. The weight of the ice and the force of the wind can easily break the power lines and even pull down the poles. So when we go out, we must stay away from poles, trees, eaves with icicles, etc. 3. When driving, be careful when sliding Freezing rain turns to ice when it falls to the ground, which will hinder traffic and increase the chance of traffic accidents. So no matter you are a novice or an experienced driver, remember four words when driving: slow down! Do not overtake, accelerate suddenly, make sharp turns or brake suddenly, and install tire anti-skid chains when necessary. 4. For long distance trips, make good plans Freezing rain can easily cause railroad tracks, waterways, and aircraft engines to freeze, causing train and flight delays. Friends who travel long distances must plan ahead, avoid the heaviest rain and snow periods, avoid areas with heavy freezing rain, pay attention to weather and road traffic information along the way, and pay attention to safety. 5. When rain or snow blocks the way, it is better to take a rest before setting off again Rain, snow and freezing weather will affect road traffic. In case of emergencies such as road closures or traffic jams, please follow the instructions of the traffic police on site and wait for the road to resume normal operation on the spot or at the nearest service station. If necessary, change to an alternate route. |
