Tianjin, December 12th (Xinhua) - According to the Central Weather Bureau, it is expected that from the 13th to the 15th and from the 14th to the 16th, there will be widespread rain, snow, and cold wave weather in the central and eastern parts of China again. Experts suggest that there is a high risk of meteorological disasters such as low temperature, rain, snow, and freezing during this round of weather. It is necessary to prevent the impact of large-scale snowfall and cooling weather on human health, transportation, and agricultural and animal husbandry production. Short term severe cooling will have adverse effects on physical health, especially causing cardiovascular and cerebrovascular diseases and colds in vulnerable populations. Zhu Zhengang, Chief Physician of the Respiratory Department at the First Affiliated Hospital of Tianjin University of Chinese Medicine, said that cold air can cause vasoconstriction and reduced circulation in the respiratory tract, leading to a weakened immune system and making it easy for pathogens to take advantage of the situation. The public should try to minimize going out, especially for the elderly, infants, and patients with underlying diseases. When going out, it is advisable to wear masks, add clothing in a timely manner, and take measures to prevent cold and keep warm. On December 11th, in front of the Drum Tower in Beijing, people are clearing snow. Since the night of December 10th, snowfall has been falling in various parts of Beijing. Xinhua News Agency reporter Luo Xiaoguang reported that low-temperature rainy and snowy weather will lead to reduced visibility, slippery and even icy roads, and frequent accidents. Shen Weisheng, Director of the Command Center of the Tianjin Public Security Traffic Management Bureau, reminds that long-distance travel should be avoided as much as possible on icy and snowy days. When driving out, it is necessary to check the vehicle in advance, remember to "slow down, control the distance, and light the tail" during the driving process, reduce changing lanes, and avoid strong meetings. Shen Weisheng stated that visibility is generally low on rainy and snowy days, and drivers should pay attention to the correct use of lighting. When visibility is low, in addition to turning on the position lights and front and rear position lights, fog lights and low beam lights should also be turned on to facilitate observation of the situation ahead and improve their vehicle recognition. It is worth noting that although snowfall is beneficial for increasing soil moisture in wheat fields, heavy snowfall and strong winds can easily cause greenhouse collapse and damage to greenhouse films, resulting in agricultural production losses. Meteorological experts suggest that the northern winter wheat region should strengthen monitoring of wheat seedling and soil moisture, and do a good job in anti freezing work; The southern region should do a good job in water and fertilizer management, disease and pest prevention and control of winter wheat and rapeseed, timely harvest mature fruits and vegetables before the cooling and precipitation process, and do a good job in storage, transportation, and marketing. On December 11th, farmers in Gangtou Village, Luancheng District, Shijiazhuang City, Hebei Province, cleared the snow on their greenhouses. In addition, with a significant decrease in temperature, the demand for energy will increase. Relevant departments should ensure energy security such as heating, power supply, and gas supply. At the same time, in response to strong winds, it is necessary to reinforce outdoor structures in advance, strengthen safety inspections of ports and various ships, and prevent adverse effects of strong winds on urban buildings, facilities, and offshore operations.
