Lead: Before the arrival of the cold wave, everyone should prepare something to keep out the cold, so as to spend this cold weather comfortably and smoothly. There are advantages and disadvantages. Although the cold wave will bring obvious cooling, it also has some beneficial effects. So, how much do you know about the benefits of the cold wave? What are the benefits of the cold wave to people? Come and learn more.

What are the benefits of cold wave?

1, which is helpful for surface heat exchange.

The cold wave has a wide range and has a great influence on nature. Few people know that cold waves can help the earth's surface exchange heat. The higher the latitude, the weaker the radiant energy received by the sun. The earth has tropical zone, temperate zone and cold zone, and the heat distribution is uneven, but the cold wave can alleviate this phenomenon. The cold wave carries a large amount of cold air to the tropical region, so that the heat on the earth's surface can be exchanged, the nature's ecology can be kept in balance, and species can be multiplied.

2. Alleviate winter drought

The cold wave can also alleviate the winter drought. Winter is a dry season, and rainfall is very scarce. When the cold wave strikes, it will be accompanied by a lot of rain and snow, and the winter drought will be alleviated in this case. There is a saying that "snow brings good harvest", which is the truth. Snow will not only bring harm, but also bring great benefits. The nitrogen content in snow is very high, almost more than five times that of ordinary water. After snowing, the nitrogen content in the soil will also increase, and the decomposition rate of organic matter in the soil can also be greatly improved. This is a natural and pollution-free fertilizer.

3. Natural pesticides

Snow is equivalent to a natural insecticide. Although heavy snow will slow down the growth rate of plants, the growth rate of plants is already very slow in winter. After snowing, it's like covering plants with a big quilt, which has a good effect of cold resistance and heat preservation. The low temperature of cold wave can kill bacteria and pests that overwinter in soil, or slow down their growth. From this perspective, there are many dangers and benefits of the cold wave.

Precautions for traveling in cold weather:

Pedestrian:

"Slow: There are many unpredictable factors in snowy days, whether walking or driving, concentration, walking slowly and driving slowly." Look: always pay attention to the surrounding car conditions and road conditions, and be ready at any time. Don't talk on your cell phone on the road. When two or more people travel, walk back and forth, not shoulder to shoulder. Don't press your hat too low to block the front view when it is cold or warm.

Steady ":It is best to wear non-slip shoes when traveling in snowy days. Don't walk too fast, keep your feet firmly, and the old man should walk with crutches. The sole should not be hard. Don't wear hard plastic flats. Ladies, it is best to wear loose, warm and non-slip cotton shoes, such as non-slip shoes or sports shoes.

Especially platform shoes, who should not wear high heels or bare soles. When walking in the snow, don't lift heavy objects, don't put your hands in your pockets, and wear warm gloves, because swinging your hands back and forth can balance your body well.

Cars:

1, careful sideslip in bad atmosphere.

The road surface is slippery in bad weather, so the driving speed should be strictly controlled. Too fast speed in corners, sudden acceleration during driving, sudden lifting of oil] or taking emergency measures can easily lead to vehicle sideslip and accidents.

2. Brake early in snowy days and be "soft".

The tricks of driving in snowy days are mainly early words and soft words. Even if you drive on the road without snow and ice, the effect of braking in winter is different from that in other seasons, because the tires and roads in winter are "hard", so you should brake early in winter.

3. Pay attention to your driving state

Many people don't pay attention to their driving state when driving in winter, which is actually very important for safe driving. Let's move our hands and feet first, at least be flexible before driving, because it's very cold in winter, and it's easy to have an accident if our hands and feet are not flexible.

4. Be careful of the icy road.

Watch out for icy roads. Dark places, bridges, viaducts and small intersections are easy to freeze, so you must be more careful when driving through these places. In any case, try to slow down and keep calm. It should be specially reminded that although passing vehicles melt the ice and snow on the main road, you must slow down before driving out of the main road, because many exits or intersections with branches are prone to ice.

5. Pay attention to the distance between cars.

Rain and snow are often accompanied by fog and light rain. At this time, we should pay attention to the distance between cars, and don't follow too closely and rear-end. When the fog is too heavy, you should slow down. You can turn on the yellow warning light to let the cars behind you see clearly, which is good for everyone.
