The data shows that six days before the Spring Festival in 2024, more than 11500 million trips. At this time, the rain, snow and freezing weather process in the central and eastern parts of China is unfolding and will continue until the 5th, which will have a great impact on the Spring Festival before the holiday and the livelihood of people in many places.
What will be the impact of this round of rain, snow and freezing weather on the central and eastern parts of China in the future? Zhai Yu, a meteorological analyst at the China Meteorological Administration, analyzed this
Zhai Yu, meteorological analyst of China Meteorological Administration: The most complicated spring rain and snow weather process since 2009 has now begun, with heavy snowfall spreading 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. The form of precipitation, whether it is rain or snow, freezing rain or ice particles, determines the degree of intrusion of warm and moist air currents. When the ice crystals in the clouds at high altitude grow large enough and fall to the ground, the temperature of the entire atmosphere is below zero degrees Celsius, and snow falls.
If there is a deep influx of warm and humid air, but the temperature near the surface layer is still below 0 degrees Celsius, the ice crystals fall into the warm layer and melt and then fall to the near surface layer, the temperature will be lower than 0 degrees Celsius, and the supercooled water will quickly freeze into ice when it touches the road surface or other objects.
Now what you see is a freezing rain observed at the Jingmen Regional Weather Station in Hubei Province during the day today, when this phenomenon appears, the road surface will become very slippery, and it is difficult to detect, so it will have a very big safety hazard for high-speed traffic safety. In addition, the icing of the wires will also cause the failure of the transmission line, which will affect the normal operation of railway transportation. In addition, the take-off and landing of aircraft flights may be delayed due to icy roadways or fuselages. It is expected that from the evening of February 1, from the eastern part of Guizhou, the western and northern parts of Hunan to the southern part of Shandong, and a large area of northern Jiangsu, the scope of freezing rain will expand rapidly and continue until February 4, and the thickness of ice may reach 10 mm or even more than 20 mm in some places. Such a long-term and intense freezing rain will undoubtedly have a great impact on the current very busy Spring Festival traffic.
Here's a reminder that if you're driving through a freezing rain area, be sure to install snow chains on your tires in advance, and wear shoes with the best anti-slip performance when you go out. If you don't have time to prepare, you can also wrap your shoes in an old towel at home, which can increase friction and play a non-slip role. In addition, it should be noted that until February 5th, the eastern part of Northwest China to the Huanghuai region in North China will continue to have snowfall for a long time, of which the cumulative snowfall in Henan and Shandong may be close, or even break through the extreme value of the same period in history, of which the snowfall is strongest from February 2nd to 4th, so it is also recommended that if we can choose, try to avoid long-distance travel during the heavy snowfall period.
How to deal with the rain, snow and freezing weather during the Spring Festival?
At present, it is the critical moment of the Spring Festival before the holiday, and the passenger flow continues to grow, but at this time, the central and eastern regions of China have encountered a wide range of rain, snow and freezing weather. So in the face of the impact of the weather on the Spring Festival and people's livelihood in various places, what measures should be taken to actively deal with it? What about disaster prevention and mitigation? Yan Daozheng, deputy director of the Department of Flood Control and Drought Relief of the Ministry of Emergency Management, interprets this
Yan Daozheng, Deputy Director of the Department of Flood Control and Drought Relief of the Ministry of Emergency Management: The Office of the National Disaster Prevention, Mitigation and Relief Committee and the Ministry of Emergency Management attach great importance to the prevention and response of rain and snow weather processes within this scope, and focus on the following aspects.
The first is to strengthen consultation, research and judgment, and scheduling, in conjunction with the Ministry of Public Security, the Ministry of Transport, the National Energy Administration and other departments, and conduct rolling consultation, research and judgment, and dispatch key provinces such as Shanxi, Henan, Shandong, and Anhui to deploy targeted prevention and response measures, and issue risk reminders and early warnings through multiple channels and high density, so as to guide the public to enhance their awareness of disaster prevention and risk avoidance, and take the initiative to prevent and avoid disasters. 
Second, for Hebei, Shanxi, Jiangsu, Shandong, Henan, Shaanxi, Anhui, Hunan, Chongqing, and Guizhou, we have launched an emergency response to low-temperature rain, snow, and freezing disasters, and dispatched three multi-departmental joint working groups to Henan, Shandong, Hunan, Hubei, and Anhui to assist in guiding the prevention and response work. 
The third is to focus on ensuring the safety of the Spring Festival, ensuring the safety of electricity, and ensuring the stability of people's livelihood, supervise and guide relevant regions and relevant departments to strengthen the investigation of hidden dangers, preset rescue forces in advance, and strictly prevent accidents such as large-scale traffic congestion, stranded people and vehicles, power interruptions and fire poisoning. 
The fourth is to strengthen the national comprehensive fire and rescue team, prefabricated warehouses to supervise and guide key areas to estimate extreme situations, improve the plan, make sufficient preparations for strength, materials and equipment, and make every effort to do a good job in snow and ice removal, cold and warmth, supply and smoothness, so as to minimize the impact on the Spring Festival and the production and life of the masses. 
In the next step, the Office of the National Disaster Prevention, Mitigation 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 dispatch key provinces and relevant departments to guide and supervise relevant work. The first is to organize forces to carry out snow and ice removal and traffic diversion control in a timely manner to prevent large-scale traffic congestion and stranded people and vehicles to ensure the safety of the Spring Festival. In terms of ensuring power supply, we will strengthen transmission line inspections and icing observations, and comprehensively adopt a combination of current ice melting and mechanical de-icing to effectively melt ice and de-ice and ensure the safety of the main network operation. In terms of emergency rescue and disaster relief, we will allocate emergency rescue and disaster relief materials and equipment in advance, make preparations for emergency rescue and disaster relief at any time, make every effort to ensure the safety of people's lives and property, and ensure that the masses are warm for the winter and holidays.
