Data shows that in the first six days of the Spring Festival in 2024, more than 1.15 billion people will travel. At this time, the process of rain, snow, and freezing weather is unfolding in the central and eastern regions of my country, and will continue until the 5th, which will have a great impact on the Spring Festival transportation before the holiday and people's livelihood in many places.

　　What impact will this round of rain, snow and freezing weather have on central and eastern my country in the future? Zhai Yu, a meteorological analyst at the China Meteorological Administration, analyzed this↓

Zhai Yu, a meteorological analyst at the China Meteorological Administration:

The most complicated Spring Festival rain and snow weather process since 2009 has now begun. Heavy snowfall spread in Henan on the night of January 31, and the impact of freezing rain on traffic in northern Anhui during the day on February 1 also began to show. . Whether the precipitation is in the form of rain, snow, freezing rain or ice particles plays a decisive role in the degree of intrusion of warm and moist airflow. When the ice crystals in high-altitude clouds grow large enough and fall to the ground, the temperature of the entire atmosphere is below zero degrees Celsius, and what falls is snow.

　　If there is a deep influx of warm and humid air, but the temperature near the ground is still below 0 degrees Celsius, the ice crystals will fall into the warm layer, melt and then fall to the ground layer, and the temperature will become below 0 degrees Celsius, resulting in supercooled water. If it comes into contact with the road or other objects, it will quickly freeze into ice.

　　What you are seeing now is a freezing rain situation observed at the Jingmen Regional Weather Station in Hubei during the day. When this phenomenon occurs, the road surface will become very slippery and difficult to detect, so it will have consequences for high-speed traffic safety. Very big safety hazard. In addition, frozen wires will also cause transmission line failures, thus affecting the normal operation of railway transportation.

　　In addition, the takeoff and landing of aircraft flights will also be delayed due to ice on the road runway or the fuselage. It is expected that starting from the evening of February 1st, the scope of freezing rain will rapidly expand from eastern Guizhou, western and northern Hunan to southern Shandong, and large areas of northern Jiangsu, and will continue until February 4th, with freezing in some places. The thickness may reach 10 mm or even more than 20 mm. Such prolonged and intense freezing rain will undoubtedly have a considerable impact on the currently very busy Spring Festival travel season.

　　I would like to remind everyone that if you drive through freezing rain areas, you must install anti-skid chains on your tires in advance, and wear shoes with the best anti-skid performance when going out. If you don't have time to prepare, you can also wrap old towels at home around your shoes to increase friction and play an anti-slip role.

　　Another thing to note is that until February 5th, snowfall will continue for a long time from the eastern part of Northwest China to the Huanghuai area in North China. The cumulative snowfall in Henan and Shandong may be close to, or even exceed, the extreme record for the same period in history. Among them, the snowfall is the strongest from February 2 to 4, so it is recommended that if we can choose, we should try to avoid long-distance travel during heavy snowfall periods.

　　How to deal with rain, snow and freezing weather during Spring Festival travel to ensure travel?

　　It is the critical moment of Spring Festival transportation before the holiday, and the passenger flow in various places continues to grow. However, at this time, the central and eastern regions of our country have encountered widespread rain, snow, and freezing weather. So in the face of the impact of weather on Spring Festival transportation and people's livelihood in various places, what measures should be taken to actively respond? What about disaster prevention and mitigation? Yan Daozheng, deputy director of the Flood Control and Drought Relief Department of the Ministry of Emergency Management, interpreted this↓

Yan Daozheng, deputy director of the Flood Prevention and Drought Relief Department of the Ministry of Emergency Management:

The Office of the National Disaster Prevention, Reduction and Relief Committee and the Ministry of Emergency Management attach great importance to the prevention and response to this round of widespread rain and snow, and have focused on the following aspects of work.

　　The first is to strengthen consultation, research, and dispatch, and work with the Ministry of Public Security, the Ministry of Transport, the National Energy Administration and other departments on a rolling basis to discuss, study, and video dispatch, and deploy prevention and response measures in key provinces such as Shanxi, Henan, Shandong, and Anhui, and implement multi-channel high-level Risk warnings and warnings are issued intensively to guide the public to enhance their awareness of disaster prevention and avoidance, and to proactively prevent and avoid disasters.

　　Second, level IV emergency response to low-temperature rain, snow and freezing disasters was launched in Hebei, Shanxi, Jiangsu, Shandong, Henan, Shaanxi, Anhui, Hunan, Chongqing, and Guizhou, and three multi-department joint working groups were dispatched to Henan, Shandong, Hunan, Front lines in Hubei and Anhui are assisting in guiding prevention and response work.

　　The third is to focus on ensuring the safety of Spring Festival transportation, ensuring power supply, and ensuring the stability of people's livelihood. We urge and guide relevant regions and relevant departments to strengthen the investigation of hidden dangers, prepare emergency rescue forces in advance, and strictly prevent accidents such as large-scale traffic congestion, stranded people and vehicles, power outages, fire poisoning, etc. occur.

　　The fourth is to strengthen the national comprehensive fire rescue team, supervise and guide key areas to predict extreme situations, improve plans, make adequate preparations for materials and equipment, and make every effort to clear snow and ice, prevent cold and heat, and ensure supply and smooth operation. Minimize the impact on Spring Festival transportation and people's production and life.

　　In the next step, the Office of the National Disaster Prevention, Reduction and Relief Committee and the Ministry of Emergency Management will continue to pay close attention to the development and changes of rain and snow weather, and provide point-to-point dispatch to key provinces and relevant departments to guide and supervise related work. One is to ensure smooth roads, organize forces to carry out snow clearing and ice removal and traffic control in a timely manner, strictly prevent large-scale traffic jams and stranded people and vehicles, and ensure the safety of Spring Festival transportation. In terms of ensuring power supply, we will strengthen inspections of transmission lines and ice-covering observations, and adopt a combination of electric current melting and mechanical de-icing to effectively melt and remove ice and ensure the safety of main grid operations. In terms of emergency rescue and disaster relief, we must allocate emergency rescue and disaster relief materials and equipment in advance, be prepared for emergency rescue and disaster relief at any time, and make every effort to protect the safety of people's lives and property, and ensure that the people have a warm winter and holidays.
