The earliest cold wave warning was issued in history. What impact will the cold wave bring?

The strong cooling caused by the cold wave will cause freezing damage to crops; The heavy snow and freezing rain brought by the cold wave may break power lines and telephone poles, and may also cause traffic hazards. The strong wind accompanying the cold wave may destroy buildings, destroy farms and cause casualties. Most parts of China may be affected by cold wave weather. Except Qinghai-Tibet Plateau and Yunnan-Guizhou Plateau, there are obvious cold wave weather in other areas, especially in northwest, northeast, north China and the middle and lower reaches of the Yangtze River.

Cold wave is a large-scale disastrous weather process, which will cause a large-scale sudden drop in temperature, strong wind, rain and snow, and have a great impact on agriculture, animal husbandry, transportation, electricity and human health. In order to prevent and mitigate meteorological disasters, before the cold wave strikes, the meteorological department will issue a cold wave warning to remind the public to take precautions. The freezing rain and snow weather brought by the cold wave is very unfavorable to transportation. It will cause the railway station switch to freeze, the railway track to be buried by snow, the communication signal to be interrupted, and the train operation to be blocked. After the rain and snow, the roads were frozen and skidded, and traffic accidents increased obviously. Cold wave attacks are very harmful to human health, and windy weather is easy to cause colds. Cold waves can also bring wind resources. Scientists believe that wind is a valuable energy source without pollution. The power generation efficiency of the world-famous Miyakojima wind power station during the cold wave is 1.5 times that of the usual one.

Cold wave is a large-scale invasion of cold air from polar regions or frigid regions into low latitudes in winter. Cold wave attacks will lead to a sudden drop in temperature, accompanied by strong winds, rain and snow. In pastoral areas, the snowstorm brought by the cold wave makes the grass deeply buried by the snow, livestock can't eat fresh grass, and hay can't be supplied, resulting in freezing hunger or disease, which leads to a large number of deaths. When the cold wave comes, keep warm and keep out the cold, and wear gloves, hats, scarves, etc. Herdsmen should prepare enough forage before winter to solve the problem of livestock feed. When there is heavy snow in the city, the relevant departments should clear the road snow in time. When the situation is serious, roads, railways and shipping traffic should be closed to prevent traffic accidents.
