The first cold snap warning in history has been issued. What impact will the cold snap have?
The strong cooling caused by the cold snap will cause frost damage to crops; Heavy snowfall and freezing rain brought by the cold snap could crush electrical wires, break telephone poles and could also cause traffic hazards. Strong winds associated with cold spells can destroy buildings, damage farms and cause casualties. Most parts of China may be affected by cold spells. Except for the Qinghai-Tibet Plateau and the Yunnan-Guizhou Plateau, other regions are experiencing obvious cold waves, especially the northwest, northeast, northern China, and the middle and lower reaches of the Yangtze River.
Cold wave is a large-scale disastrous weather process, which will cause temperature dropssudden large-scale eradication, strong winds, rain and snow, and will have a significant impact on agriculture, animal husbandry, transportation, electricity, human health, etc. In order to prevent and mitigate weather disasters, the weather department will issue a cold wave warning before the cold wave hits to remind the public to take precautions. Freezing rain, snow and bad weather brought by the cold snap are very detrimental to transport. This would cause station switches to freeze, railway tracks to be buried in snow, communication signals to be interrupted and trains to be hampered. After the rain and snow, the roads became icy and slippery and road accidents increased significantly. Cold waves are very harmful to human health, and windy weather can easily cause colds. Cold wavescan also provide wind resources. Scientists believe that wind is a valuable, non-polluting source of energy. The world-famous Miyakojima Wind Power Plant in Japan has a power generation efficiency 1.5 times higher than during normal cold wave periods.
Cold wave is a large-scale invasion of polar or freezing cold air in mid- and low-latitude areas in winter. A cold wave attack will cause a sharp drop in temperature, accompanied by strong wind, rain and snow. In pastoral areas, blizzards caused by the cold snap buried grass deep in snow, livestock could not eat fresh grass, and hay was not provided, causing frost, famine or disease, leading to large numbers of deaths. . When the cold snap arrives, be sure to stay warm and protect yourself from the cold, wear gloves, hats,scarves, etc. Shepherds must prepare enough fodder before winter to solve the problem of feeding livestock. When it snows heavily in the city, the competent services must immediately clear the roads. When the situation is serious, roads, railways and maritime traffic must be closed to avoid road accidents.
