How to prevent cold waves? How to reduce the harm caused by cold waves?

Cold wave. The rain and snow and cool weather that bring it will cause visibility.

Phenomena such as reduction, ground icing, snow on the roads and strong winds pose a great threat to the safety of road, rail, air and sea transportation.

Prevention of cold waves1.When the temperature plummets, you should pay attention to adding clothes to keep warm, especially to keep your hands and face warm.

2.Close doors and windows and secure outdoor structures.

3.Beware of slipping and falling on the road when you go out.

4.Elderly and infirm patients, especially cardiovascular.

Patients, asthma.

People who are sensitive to temperature changes, such as sick people, should not go out as much as possible.

5.Take care of your rest and don't get overtired.

6.Beware of gas poisoning.

In particular, families that use coal stoves for heating should be more vigilant.

7.Weather forecasting should be strengthened.

Post accurate cold wave messages or alerts in advance.

8.Publish accurate cold wave news or emergency reports to enable ships at sea to return to sea in time.

9.Prepare crops and herds for the cold in advance.

The cold wave is a kind of disastrous weather in winter, and the masses are accustomed to calling the cold wave a cold wave. The so-called cold wave is a weather process in which cold air from the north invades our country on a large scale to the south, causing a wide range of sharp cooling and northerly winds. Cold spells generally occur in late autumn, winter, and early spring.

China's meteorological department stipulates that if the cooling caused by cold air intrusion reaches more than 10 in a day, and the minimum temperature is below 5, the cold air outbreak process is called a cold wave process. It can be seen that not every cold air moving south is called a cold wave.

Severe weather such as severe cold, strong winds, and frost brought by cold waves.

It will have an adverse impact on industrial and agricultural production and people's livelihood. When the cold wave brings frost, the temperature will drop below 0, and the water in the intercellular space between the cells of the plant will freeze, and after the water freezes, the volume will increase, resulting in a kind of pressure, which will make the water in the cells continue to penetrate outward, causing the cells to dehydrate, causing the plant to partially wither or completely die. The vast number of farmers in China have accumulated rich experience in the defense of cold waves and frosts, such as fumigation, irrigation, mulching and other methods before frost occurs, so as to increase the air temperature and soil temperature of farmland to reduce the harm of frost to crops.

The first thing I want to do is to pay attention to personal warmth and increase clothing; The second is to pay attention to the weather forecast in time; The third is to maintain physical strength and rest more. It's best to stay indoors to reduce the harm caused by the cold spell.

First of all, we must regularly ** weather forecast, pay attention to clothing and warmth, especially the protection of hands, feet and face, close doors and windows to prevent cold air from entering, especially people with cardiovascular disease and special sensitivity to weather changes, do not go out.

Measures taken: Listen to the weather forecast and stay informed of weather changes; Artificial smoke screens can be used to prevent frost; Farmers who plant greenhouses should cover the greenhouses with cold-proof grass curtains in time; Individuals should do a good job of cold protection; **It is necessary to do a good job in the early warning system and do a good job of prevention in advance.

Keep up to date with the weather forecast and stay up-to-date with the latest weather information. For individuals, it is necessary to increase or decrease clothing in a timely manner, and to do a good job of cold protection when going out.

To prevent the cold wave, it is first necessary to close the doors and windows before the cold wave comes, tighten the outdoor structures, residents should pay attention to the cold and keep warm, the department should start the defense plan in advance according to the situation, and agriculture should take active measures. The severe cold, strong winds, frost and other bad weather brought about by the cold wave will have an adverse impact on industrial and agricultural production and people's lives. Before the frost brought by the cold wave, fumigation, irrigation, mulching and other methods were adopted to increase the air temperature and soil temperature of the farmland to reduce the damage of frost to crops.

The effects of the cold spell.

The cold wave has caused great harm to transportation due to the rain, snow and freezing weather, and at the same time, it will also bury the tracks of railway stations with snow and the failure of communication signals, which will delay or hinder the operation of trains.

Rain and snow can also make roads slip and traffic accidents to rise.

The arrival of the cold wave will also be very harmful to human health, and the windy and snowy weather will also cause a series of diseases, such as colds, tracheitis, coronary heart disease, etc., and will also aggravate the diseases of some patients.

Favorable effects of the cold spell.

Cold waves also contribute to the exchange of heat on the Earth's surface, and as the dimensions increase, the Earth's reception of solar radiation gradually decreases, as the Earth forms tropical, temperate and cold zones. Cold spells can allow cold air to invade the tropics, allowing the exchange of heat on the ground to help maintain ecological balance.

The cold wave is also a guarantee of good wind and rain, the climate is dry in winter, and the cold wave will also bring large-scale rain and snow when it invades southward, alleviating the drought problem in winter. In addition, the nitrogen content of snow water is usually high, which also gives the land a chance to decompose, increasing the organic fertilizer in the soil.

A cold wave is a major disaster. The weather will change dramatically. There is a local cooling and windy weather, rain and snow.

It has a certain impact on agriculture and human health. When the cold wave comes, we must add more clothes. Non-slip, prevent gas poisoning, reinforced.

Prevent getting sick.

It will affect the health of the agricultural transportation industry, the electric hand power industry and the human body, and will also cause a lot of rain and snow weather, which will also cause roads to freeze, pipes to break, and economic damage. Gao Peichi must close the doors and windows, and then wear more clothes, and Qi Li wears non-slip shoes.

It will cause many people to catch a cold. It will affect people's health, sometimes arthritis, and may also affect patients with cardiovascular and cerebrovascular diseases. At this time, we must pay attention to keeping warm, drink more hot water, and never eat raw and cold food.

1. The sluggish cooling of crops has caused freezing damage to crops and caused agricultural losses.

2. The secondary disasters brought by it, such as no oak gale, heavy snow, and freezing rain will cause losses in animal husbandry.

3. Snow, strong winds, etc. block traffic.

4. Destruction of communication facilities and transmission lines.

The cold wave is a large-scale climatic process, which will cause a wide range of cooling, rain, wind and other weather in the coastal area, which will affect the local agriculture, electricity, transportation, navigation and people's health.

During the cold wave, it will drop sharply, which will lead to the freezing of household and industrial water pipes, the freezing of roads and the destruction of power facilities, causing freezing damage to crops, which will affect the economy, because it will cool down all of a sudden, and it is difficult for people with poor physical fitness to accept it, and it is easy to cause colds and fevers; When the cold wave comes, we must take effective protective measures, and do not walk around as in the past to avoid some sudden situations, so as to resist the impact of frost damage caused by the cold wave.
