How to prevent snowstorm

Snow disaster refers to the weather in which strong cooling in winter and spring and strong wind roll up snow on the ground with snowfall or strong wind, which causes great harm to road traffic, urban residents' life and animal husbandry production. So, do you know how to prevent snowstorms? Let's introduce you to the measures to prevent the snowstorm. Let's have a look.

Measures to prevent snowstorm before heavy snow;

1. Pay attention to the weather forecast.

2. Be prepared for cold protection, including indoor heating equipment and clothes.

From various countries? Blizzard? Emergency measures 1. Canada's national cooperation

The winter in Canada is long and snowy, and the local government has accumulated rich experience and formed a set of more efficient and systematic emergency countermeasures.

In Canada, the responsibility of clearing snow in time and ensuring smooth roads lies mainly with the provincial and municipal governments. Among them, the provincial government is responsible for the highways within its jurisdiction, and the municipal government is responsible for the roads in the city, but the highway sections located in national parks are the responsibility of the federal government. According to statistics, the annual snow clearing cost in Canada is as high as 654.38+0 billion Canadian dollars (about 765.438+0.7 billion yuan), and governments at all levels also have special annual snow clearing budgets. All provinces and cities have permanent snow clearing institutions to cooperate with private snow clearing companies in disaster prevention.

Snow sweeping in Canada basically relies on mechanized operations, and each city is equipped with systematic snow sweeping equipment, such as snow shovels, salt spreaders, snow melting vehicles, snow removal vehicles, snow transport vehicles and deicing vehicles. Snow shovel is divided into main road snow shovel and sidewalk snow shovel. However, according to different conditions, the salt in the salt spraying truck is dry and wet, and the composition is different.

Snow removal in Canada not only has priority, but also has time requirements. First, highways and urban main roads are cleaned, followed by highway auxiliary roads, bus lines and inclined sections, and finally other streets. Snow on expressways and main roads is generally required to be completed within 2 to 4 hours after snow stops, 4 to 6 hours after snow stops on auxiliary roads and bus lines of expressways, and 24 hours at the latest after snow stops on other roads. Specialized personnel will closely follow the weather forecast from June 65438+February to March of the following year, patrol the area under their jurisdiction for 24 hours, and monitor the road conditions in real time. In case of emergency, they will start the corresponding plan.

In order to minimize the impact of snowstorms, Canadian provinces and cities pay special attention to mobilizing the cooperation and participation of the whole society. The website of Environment Canada not only publishes detailed weather forecasts of different cities in different time periods every day, but also provides daily weather forecasts for the coming week, and timely issues extreme weather warnings such as snowstorms. At the same time, all provinces and cities have free real-time traffic information hotlines. Radio and TV stations usually broadcast local weather and road conditions every half hour. Provinces and cities have also published their budgets, operating procedures and standards, and complaint telephone numbers on their official websites for public supervision.

Canadian provinces and cities often introduce the knowledge and skills of preventing snow and ice weather to the public in various ways, such as:

■ Replace snow tires for cars before winter;

■ During long-distance running, check the weather forecast and road conditions in time and arrange the trip reasonably;

■ Always keep water, first-aid medicine, flashlight and lighter in the car, and always keep antifreeze, small barrels of gasoline, snow shovel and small packets of salt or sand in the trunk;

■ If there is a snowstorm forecast, try to drive fewer private cars, take more buses and reserve food, medicine and water for 48 hours.

2. Japan encourages? Save yourself?

Japan has a maritime climate with abundant precipitation, and there are frequent snowstorms in northeastern areas such as Hokkaido and Hokuriku. However, compared with typhoons, tsunamis and earthquakes, snowstorms are only minor disasters in the eyes of the Japanese. Tire chains are indispensable in the trunk of Japanese cars in the north. One of the major tasks of the local government is to regularly dispatch bulldozer-type snow sweepers to ensure the smooth flow of main roads. In northern Japan, the roof is made thin to prevent the ceiling from collapsing under the snow.

In southern Japan, snowfall will also bring problems. Because it melts when it snows, there is water on the road, and then it may freeze, which is the enemy of Japanese winter traffic. Unfortunately, Japan's rugged terrain and many sloping bridges make this harm more serious. The Japanese have developed many deicing vehicles for this purpose. But the more practical way is on the side of the road. In places where there are many slopes and bridges on Japanese expressways, yellow plastic boxes shaped like lifeboats can often be seen on the roadside, marked as the property of the Japanese government. Free entry? In that case. On snowy days, Japanese people often take plastic buckets and take some white crystals out of such boxes with shovels. These plastic boxes are filled with deicer, and the main component is salt. But why can you get it for free? This is because Japanese houses are crowded, many paths are extremely narrow, and few outsiders walk around. It is difficult and uneconomical for government vehicles to go to such places to remove snow and ice. And the deicer is provided to the residents themselves free of charge, and the roads in residential areas are usually kept very safe. On the surface, giving away the deicer for nothing is a loss, but in fact, the Japanese government has made a fortune by counting the labor of sweeping snow.

Swiss technology is supreme.

Switzerland is a world-famous ski resort and a place where avalanches frequently occur. To this end, many ski resorts in Switzerland have set up protection, monitoring and alarm systems. The Swiss Federal Snow and Avalanche Research Institute in Davos is one of only two professional research institutes in the world. The Institute has established several remote automatic observation stations in the Alps, equipped with instruments for measuring wind speed, snow thickness and temperature. After the digital transmission collected by the Observatory arrived in Voss, the Institute analyzed it and issued an avalanche warning report to the public twice a day.

A Swiss sports company has launched a sports activity called "skiing" for skiers. Life bag? Airbag ski suit, similar to life jacket. When encountering an avalanche, the user pulls down the drawstring of the automatic inflation device, and the airbag begins to inflate, thus providing head protection for the user and ensuring that the user will not fall when falling with the collapsed snow, and his head will always be upward. This can prevent the user from being knocked unconscious by a violent head impact. According to statistics, about 20% avalanche victims died of coma. This set of airbags weighs 3 kilograms and is brightly colored, which is convenient for rescue and search. Once buried under the snow, about 150 liters of air stored in the airbag can be used as oxygen supply, prolonging the life of users.

4. The United States is prepared in advance

What is the most common method used by governments around the United States to deal with snowstorms? Technology? Is to be prepared in advance.

Before the snowstorm comes, the New York City Government will advise local residents to park their vehicles away from the main roads on weekends, so as to facilitate the snow sweepers to clean the main roads quickly. The New York City Government will also let sanitation workers stick to their posts. At Kennedy International Airport, it is not a problem to clear 500 tons of snow every hour.

The Washington city government also warned that drivers may face a fine of $250 if they park their vehicles on the main street and block the traffic of the government, health and commercial departments, and they must pay the towing fee out of their own pockets. Major cities in the east, such as Boston, began to provide shelter for those in need. The Philadelphia city government urged local residents to help take care of the elderly among neighbors and relatives to ensure that their food and clothes were not affected by the snowstorm.
